Sherwood® Solid Carbide Drills

General-purpose drills for drilling a wide variety of metallic and non-metallic materials. Point angle: 118°. Tolerance of diameter: h7. Tolerance of shank: h6. Supply unit. All diameters - 1 pce. Manufacturing Standard: BS 328, DIN 338.

J102 Solid Carbide Jobber Drills

Dormer 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 A100

Guhring Drills Taper Shank HSS

General-purpose drills to drill steels with a tensile strength up to 1.000 N/mm2, cast steel, grey cast iron, malleable cast iron, nickel brass and graphite. Point angle: 118°, helix angle: normal, relief angle: normal, tolerance of diameter: h8. Manufacturing Standard: DIN345.

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.
