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 Drills Taper Shank HSS

Suitable for single and multi-spindle drilling machines. The taper shank being the engineering industries recognised standard and most widely used method for holding and driving cutting tools. Manufactured to BS328;Part 1:1986, DIN345RN, DIN343RN.

For all dimensional specifications please refer to our catalogue.

Series T100 (MT2) - Inch

Guhring 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.

Sherwood Gauge Drills HSS Steam Tempered

General purpose drills for steels, cast steel, grey cast iron, malleable cast iron, nickel brass, aluminium alloy and graphite. Point angle: 118, helix angle: normal, web thickness: standard, relief angle: 8 - 20, tolerance of diameter: h8, tolerance of shank: f11. Manufactured to ANSI B328, BS 328 and DIN 338.

Number & Letter Gauge Drills:
Gauge drills are still in common use in the U.S. In the past, they were popular elsewhere, but now have been largely discarded in favour of metric sizes. When using a gauge rather than a standard measurement of size the user has to refer to a table of gauge sizes. For example, to drill a hole which is 10 thou (thousandth of an inch .0010) bigger than a 1/8 inch bolt, the user must first work out that 1/8 inch is 125 thou, so the hole size needed is 135 thou, and then must look up in a reference book which gauge drill bit is closest to this diameter - a number 29. Number gauge sizes are similar or equivalent in some respects to, but different from, American wire gauge. Number gauge is usually used from size 80 (the smallest) to size 1 (the largest) followed by letter gauge size A (the smallest) to size Z (the largest). Number gauge is actually defined down to size 97, but these smaller sizes are rarely encountered. It happens that as the technology for making small drill bits and drilling small holes has become more available, metric drills have become the norm.
