Standard HSS/HSCo Drills
Dormer’s standard drills are manufactured in HSS or HSCo with a blue, bright or bronze finish. Certain drills are coated with Titanium Nitride (TiN), Titanium Aluminium Nitride (TiAlN) or Titanium Carbo-Nitride (TiCN), where this would combine with the design of the tool to bring higher productivity and longer tool life.

Drill lengths can be divided into jobber, stub, long series and extra length. Jobber length drills produce hole depths of up to 4 x diameter, whilst stub drills have a shorter flute length and produce hole depths of up to 2.5 x diameter, which makes for good drill stability.

Flute geometry is designed to take into account the cutting behaviour of the workpiece, for example, slow helix drills for short
chipping materials and quick helix drills for long chipping, ductile materials.


Three types of shank are offered as standard – straight shank (cylindrical), Morse taper shank and stepped shank (with whistle notch DIN 6535 HE or without whistle notch DIN 6535 HA). The choice of shank is usually dictated by the machine being used.
For maximum productivity, greater tool life and hole accuracy, careful drill selection and the use of correct feeds and speeds is essential.

 

Jobber Drills
Increased flute space and improved web design make for a reduction in cutting forces, whilst the Special P.S. point on the A001 Jobber Drill facilitates penetration, improves hole size and affords accurate centering. The blue flutes and bronze lands and point of the A001 make it easy to identify, whilst the Dormer Silver RingTM singles it out as unmistakably Dormer.

  • Offers higher productivity when compared to standard geometry drills
    Capable of Producing holes up to 2 1/2 diameter depth
  • Intergrated web-thinning, with no compromise on overall strength of the drill
  • Reduced cutting forces required to drive the tool through the work piece throughout the life of the tool
  • Consequently, reduced wear and tear on machine tools
  • Designed using the latest Computer Aided Engineering (CAE) Technologies, including Finite Element Analysis an dan accurate, optimised 3D model, resulting in the best design solution

CTW™Technology

The geometry has been developed to incorporate CTW™ (Continuously thinned web) Technology. This means that when the user re-point grinds the drill, the resultant point is already thinned.

Traditionally, web thinning is performed as an additional operation after point grinding. A drill point is thinned by shortening the length of the chisel edge to reduce the thrust force needed when drilling. With CTW™ Technology the chisel edge length is minimise, which reduces the thrust force required when drilling, whilst still maintaining the sectional strength of the tool.

By integrating the web-thinning feature within the flute form, the desingn is effectively thinning throughout the life of the drill, without passing on the costs and complexities associated with this additional operation to the customer.


Vanguard ISO Taps

 

Since their launch, Dormer's programme of ISO application taps - VANGARD - have attracted much praise from many of the country's most well known and successful manufacturing companies. An impressive achievement considering the high expectations that always accompany any new products manufactured by a market leader

Today Dormer have improved on this already successful programme with the addition of eight new products, including a range of Metric Fine Thread and Titanium Carbo-Nitride TiCN) coated taps which offer the user even greater levels of choice, performance and tool life.

Vangard Taps are manufactured from premium quality HSCo steel to ISO class 2 tolerance, in order to produce metric threads to 6H tolerance and UNC/UNF/BSPF threads to 2B tolerance.
Cutting geometries and surface treatments have been developed to ensure that each tap will give optimum performance for the application material group specified. The benefits of which will be accurately sized threads, high productivity and longer tool life.

Each tap is easily identified by its coloured rings, with every colour representing a specific AMG (Application Material Group).
 

Vangard for High Tensile Steels
Red Vangard are suitable for tapping steels with high tensile strength, 1000-1300 N/mm2 and hardness 250- 35OHB. The geometry of these taps allows them to be used on a range of alloy steels including hardened and Tempered materials.

Standard Taps


E200 Straight flute


E262 Spiral flute


E265 Spiral point


E422 Interrupted thread


E328 Fluteless

Dormer’s standard taps are manufactured in HSS, HSCo and HSCo-XP, with bright, nitrided and TiN coated finishes. There are three main flute forms, straight flute, spiral flute and spiral point. The most commonly used are the straight flute taps, which can be used for through and blind holes in a wide range of materials. They are supplied in one of three chamfer leads, Taper, Second and Bottom, but are also offered as serial taps.

Spiral flute taps have a right hand spiral and are used mainly for tapping blind holes, as the swarf is drawn out of the hole via the flute to prevent build up in the flutes, which could lead to chipping or tap breakage. Spiral point taps, sometimes known as gun-nosed taps, direct the swarf ahead of the tap and are used where through hole tapping is carried out. They can be used in blind hole applications, provided sufficient room is left at the bottom of the hole to accommodate the chamfer lead length and the swarf produced.

Dormer also offers interrupted thread taps – alternate teeth are removed, to reduce tapping friction and allow lubricant to reach the cutting edges more easily, which is ideal for more difficult to machine materials.

Fluteless taps are excellent on ductile materials, but also produce very good results on some steels and stainless steel. These taps do not have cutting edges, but a thread is produced by deformation of the component material. The result is a strong thread and no swarf.

For maximum productivity, greater tool life and accuracy threads, careful tap selection and the use of correct feeds and speeds is essential. Please consult Dormer’s renowned Application Material Group tables in the catalogue or the Product Selector for recommended speeds and feeds for the material to be machined.


Solid Carbide Taps


T100


T110

Dormer produces two ranges of Solid Carbide Taps, whose main function is to allow threads to be made in hardened steels, with a hardness range of 49 – 63 Rockwell. Both taps are for machining through and blind holes - the T100 is for AMG 1.7, the T110 for AMG 1.8. The T110 has extra flutes for improved chip breaking and removal

Dies


Dies are used for external threading. Manual threading is the most usual method although machine threading is sometimes used for simple tasks. A solid die usually cuts more accurately than a split die. However, dies which are supplied solid may be split

Chromium Steel Tools:
Thread cutting tools made from chromium steel are especially suited for manual threading. Chromium steels have a lower red hardness than high speed steels. This means that under comparable machining conditions, they will have less wear resistance than high speed steels.

Generally speaking, Dienuts are used for reclaiming or cleaning out existing threads by hand. They tend to be of a more robust construction and should only be used in exceptional circumstances to cut a thread from solid.


Milling cutters


Dormer manufactures a wide variety of standard cutters to cover a wide range of milling applications, for example, slot milling, semi-finishing, end milling and roughing.

The standard cutter ranges are manufactured in HSS, HSCo and HSCo-XP with bright finish, TiCN or Super-R coatings. HSS is for general use in most materials, HSCo can be run at higher speeds for increased productivity, whilst HSCo-XP is a powder metallurgy cobalt steel, which gives added toughness and edge strength to the cutter. TiCN coating on cutters reduces surface friction, whilst Super-R multi-layer coating exhibits low internal stress and gives high toughness and wear resistance.

As a guideline, the following cutters are used for the following operations:-

End Mills For profile milling and producing open slots where a plunge feed is not required
Slot Drills For producing precision slots and keyways, they are centre cutting and can plunge feed to produce closed slots or pockets
3 flute Slot Drills These combine the roles of the slot drill and the end mill, enabling greater productivity than a 2-flute slot drill, due to the additional tooth.
Ball Nosed Slot Drills Designed to produce slots and profiles with a radius form
Roughing Cutters Designed for applications where rapid metal removal is required. The sinusoidal chipbreaker profile is for general roughing, whilst the truncated chipbreaker profile is for roughing where a better quality finish is required.

Dormer standard cutters are available in flatted, cylindrical and screwed shanks. Flatted shank provides the best rigidity for cutters, even at their maximum operating conditions, resulting in a better tool life. Cylindrical shank tools are clamped in a collet type chuck, enabling ease of axial movement. Screwed shank cutters can be accommodated by one holder through the use of different collets.

British standard cutters’ overall and cut lengths (standard and long) are different from DIN and ISO standards (short, medium, long and extra long). Please consult the Dormer catalogue for nearest equivalents.

For maximum productivity, greater tool life and accuracy, careful cutter selection and the use of correct feeds and speeds is essential. Please consult Dormer’s Application Material Group tables in the catalogue or Product Selector for recommended speeds and feeds for the material to be machined.


Primax Milling Cutters


featuring


The S002, S033 and S044 cutters feature a unique silver coloured coating from Dormer. This multi-layer coating is specifically designed to bring you the best performance in a wide range of applications.

 

 

Primax; the new high performance cutting tool programme from Dormer Tools offers the professional engineer a comprehensive range of End Mills and Roughing Cutters with geometry designed to achieve unbeatable metal removal rates with increased productivity at lower cost. Primax cutters are produced exclusively from powder metallurgy steel (HSCo-XP) which guarantees an excellent resistance against wear at elevated temperatures and a high end toughness due to excellent distribution of carbons present in this material.

Geometry
Primax Roughing Cutters are available with three different types of cutting geometry;

NR:
Round chipbreaker for roughing

These cutters are used for general roughing work where it is important to have as large an exportation of material in as little time as possible. The regrinding of these cutters should always be carried out in the flutes.

HR:
Chipbreaker fine, round profile for roughing

These cutters with a fine round chipbreaking profile are especially appropriate for work on high resistance steels (up to 1200 N/mM2) as well as Titanium and Nickel alloys.

FS:
Chipbreaker flat ground fine for roughing and semi-finishing

These cutters with a fine flat chipbreaking profile are employed for the semi-finishing of steels and non-ferrous materials.

Lengths, Shanks & Finishes

Primax Cutters are available in Short (DIN 327), Standard (DIN 844K) and Long (DIN 844L) series lengths with the option of Screwed, Flatted or Morse Taper shanks. There are two standard finishes; Bright and TiCN (Titanium Carbo-Nitride)


Reamers

 

Dormer Tools produce a range of Reamers to finish holes to H7 tolerance. Reaming has always been considered a finishing process and drilling a roughing process. Today, however, many tolerances that used to need a reaming process, can now be met by high-tech drills, such as in the CDX and ADX ranges.

Most common Reamers have a left hand helix because the main application is in through holes requiring chips to be pushed forward. For blind holes, Reamers with straight flutes or right hand reamers are recommended.

Reamers only cut on the bevel and taper leads; the lands on the body do not cut. They are normally designed with an uneven pitch and an even number of teeth to prevent chatter and ensure good hole surface finish and roundness. They include Hand, Chucking and Machine Reamers with straight or Morse taper shanks. They are available in different materials, including carbide which offers the greatest resistance to wear. Carbide reamers are successfully used to cut steels on rigid machine set ups, but often, High Speed Steel designs will be more cost effective.

HSCo Application Reamers
Available in three flute styles. The B500 straight flute reamer is primarily for blind holes and for short chipping materials (AMG 3, 6.2,6.3,6.4). The B156 spiral flute reamer is ideal for through holes in most materials (AMG 1 - 6) where an interrupted cut is encountered. The B157 quick spiral reamer is designed for through holes in long chipping materials (AMG 1, 2, 4, 5, 6, 7). All are supplied with straight shanks to DIN 212.
Manufactured from HSCo steel for longer edge life and higher cutting speeds.

Countersinks and Counterbores

Countersinks are used for deburring and/or counterboring existing holes in most materials. However for hard and abrasive materials, the use of a TiN or TiAlN coated tool is recommended. There are also countersinks with specific geometry for the toughest materials.

Single-edge countersinks provide excellent roundness and are also used for centring.
Triple-edge countersinks are easy to regrind and work without vibration.
Multi-edge countersinks can be used for deburring and counterboring difficult to machine materials.
