Dormer Solid Carbide Drills

The new Dormer MP-X range of multi-application carbide drills are cost effective, high performance drills that offer high productivity and supreme value for money. A wide range of materials can be machined using a minimum number of drills, to reduce stock-holding and associated costs.

MP-X Solid Carbide Drills

Dormer MP-X solid carbide drills deliver the following benefits and features:

Benefits
? Exceptional value with no compromise on quality.
? High productivity.
? Excellent hole quality.
? Availability.
? Reduced tooling costs.

Material
Micro-grain carbide for an excellent combination of hardness and toughness, resulting in high wear resistance and longer tool life.

Coating
Multi-layer titanium aluminum nitride (TiAlN) coating gives:
? Improved stability of cutting edges.
? Outstanding wear protection.
? High hardness properties.
? High toughness and oxidation stability
? Longer tool life and higher productivity.

Flute Geometry
Strong web design gives excellent crosssectional strength and facilitates chip evacuation.

Point Geometry
140 point angle with good centring capabilities and low thrust force design, suited to multiapplication drilling.

Multi-Application
Multi-application drilling across a wide range of materials, including:
? Carbon and alloy steels.
? Stainless steels.
? Cast iron.
? Aluminium.
? Magnesium alloys.
? Copper.

Suitable for Regrinding
The quality of design will allow consistently high levels of performance and tool life after the product is reconditioned, providing further cost reduction benefits.

HSCo Heavy Duty Drill For Stainless Steel - Series XT34 - Imperial

Sherwood Jobber Drills Steam Tempered HSS

Suitable for drilling steel, cast steel, alloyed and unalloyed, grey cast iron, spheroidal iron, sintered powder metal, German silver and graphite. Manufactured to BS328/DIN338RN.

Black Finish (W-Finish)
This is the most common surface finish and is the result of a steam tempering operation in which steam is passed over the product during a controlled tempering cycle, producing a black oxide layer. Black tools are generally recommended for ferrous applications where the oxide layer aids chip flow, helps to dissipate heat by retaining some coolant on the tool surface and also helps to prevent the tool from staining.

Series J100

Dormer Stub Drills HSS TiN Tip Coated

Designed for increased productivity and tool life compared to standard stub drills. TiN coating has been applied to 35%-50% of the flute length (dependent on drill diameter) to keep cost down and lower the cost per hole. The 135 split point is advantageous for the pre-drilling of rivets and for drilling in sheet metal. Suitable for drilling alloy steel, carbon steels, cast iron, titanium and aluminium. Manufactured to DIN1897, ANSI.

Series A022 Stub Drill HSS TiN Tip Coated - Metric

Guhring Stub Drills Carbide SL

Carbide drills deliver a quantum leap in high speed holemaking performance and tool life that manufacturers have been asking for. Carbide tooling provides faster cutting rates, longer tool life, better positional and dimensional accuracy and improved surface finish. Short cycle times and tighter tolerances translate into maximum machine utilizations, better part quality and optimum holemaking cost savings.

Series 5516

Sherwood Jobber Drills Steam Tempered HSS
