Assortment box of fully ground HSS cobalt drill bits.
Manufactured to DIN 338.
5% Cobalt gives increased heat hardness which helps extend the life of the drill bit.
135° split point is self-centring which helps to reduce thrust, friction and heat and aids easier penetration.
Efficient clog-free swarf clearance.
Suitable for drilling high carbon steel and stainless steel.
170 pieces.
Supplied in tough composite storage case.
Sizes: 1mm to 8mm in 0.5 increments (10 of each).
