The HSS Step Drill Bit delivers fast, precise drilling in multiple diameters with a single bit, eliminating the need for pre-punching thanks to its self-centering split-point tip. Made from durable high-speed steel (HSS), it features a CNC-ground spiral flute for efficient chip removal, reduced vibration, and smooth, accurate cutting. Laser-marked hole sizes provide easy identification, while the 3-flat shank prevents slipping in rotary drills and drivers for reliable performance on every job.

Features:

• HSS Step Drill Bit performs smooth drilling in several diameters with one drill bit
• Pre-punching is not necessary as the split-point tip allows for an easy start
• CNC ground spiral flute enables optimised chip removal and less vibration for even drilling
• Highest cutting smoothness due to axial and radial relief grinding
• Made of HSS for a long lifetime. Laser-markings for hole diameters.
• 3-flat shank prevents slipping in the chuck of rotary drills and drivers
