About this product
The Dormer A100 is a jobber drill bit made from High Speed Steel (HSS), suited to general-purpose engineering work in a range of materials. It features a 118° point angle for good self-centring, reducing the risk of the bit wandering when starting a hole, and a straight shank for secure fitting in standard drill chucks.
Manufactured to DIN 338 and steam tempered, it is suitable for both hand-held and machine drilling applications.
