Dormer Machine Taps

MTT-X taps are manufactured from premium quality vanadium powder steel, branded HSS-XS1, for an unbeatable combination of toughness, edge strength and wear resistance. This winning combination enables them to withstand the stresses of threading in tough materials. Special gold finish with bright flutes/thread, or steam tempering (blue) guarantee a smooth cutting action with less build-up on the cutting edge.

Dormer 2 Flute Slot Drills Threaded Shank HSS

Used for milling keyways and slots in one unit. Bright finish. Flute type: 30 helix. Manufactured to BS 122: Part 4: 1980.
Material:
XS1 HSS powder metallurgy steel. This provides a finer and more consistent grain structure than HSCo resulting in a tougher product able to more easily withstand the shock load and intermittent cutting associated with milling operations. Tool life and wear resistance, exceeds standard HSS and is comparable to HSCo cutters. Superior edge strength and rigidity, resulting in improved surface finish and slot consistency equal to and in some cases better than HSCo. A productivity increase of around 40% over existing HSS cutters. Flute and overall lengths: to BS122/4.
Finish: bronze finish: provides a uniform structure and hardness at the tool surface, whilst also aiding tool identification.

Short Series C191 - Inch

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.
