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

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.
