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.

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

Guhring NC Spotting Drills HSS TiN Coated

Special drill for accurate and fast spotting on NC machines, jig drills and other capital-intensive boring machines. For countersinking and chamfering of tapping holes in one operation. N.B. Only suitable for shallow depth drilling. Type N: Guhring standard, overall lengths to DIN1897. TiN coated increases tool life or increased cutting speeds. 90 Point.
