HSS Drill Bits - Countersunk

HSS stands for High Speed Steel. HSS drill bits are also commonly called twist drills or jobber drill bits.

Our countersunk drill bits feature a 90 degree cutting head angle for precise recess drilling, allowing for flush fitting of fasteners. These drill bits have three flats on the shank in order to prevent the bit slipping in the chuck.

Bits in this range are ideal for drilling sheet metal, aluminium, plastic, hardwood and soft woods.
