The Faithfull long series metric HSS jobber drill bits are the same high quality as the professional HSS drill bit range but in a longer length for deeper drilling requirements. Designed to meet the requirement of the professional user, these drills are manufactured from M2 grade steel and are fully ground to meet the requirements of DIN 388 featuring a 135° non slip split point. They have a robust design which gives less breakage, an easier hole start and improved penetration. The Long series professional HSS drill bits are suitable for use in alloy steels, carbon steels, cast iron, hardened alloy steels and stainless steels.
