Product information

Description

Step Drill Bits Bosch HSS 2608587427 are high-speed steel step drills with a 3-flat shank designed for drilling and enlarging round holes in thin materials. The split-point tip allows easy starting without pre-punching, while CNC-ground spiral flutes support efficient chip removal and reduced vibration. Laser-marked diameter figures in the flutes and axial and radial relief grinding ensure smooth, burr-free cutting and long lifetime when used with coolant.

Advantages

The HSS construction provides high wear resistance and durability for cutting non-ferrous metals, sheet steel, stainless steel and plastics. The step geometry enables multiple hole diameters with a single bit, saving tool changes. The split-point tip reduces wandering at start, and the 3-flat shank prevents slipping in the chuck while enabling secure high-torque transmission. Laser marking on the spirals gives clear, durable diameter identification.

Suitable for

Drilling and enlarging holes in non-ferrous metals (aluminium, brass)
Working with sheet steel and stainless steel
Drilling through plastics and sheet plastic
Deburring and stepwise hole size adjustment

How to use

Mount the step drill bit in a suitable drill or drill press with a compatible chuck, ensuring the 3-flat shank seats firmly to prevent slipping. Select an appropriate drilling speed for the material (lower speeds for stainless steel, higher for non-ferrous metals and plastics) and apply cutting fluid when working with metals to extend tool life. Start drilling with controlled feed pressure; the split-point tip will centre and reduce walking. Use steady, even pressure while stepping through the diameters until the desired hole size is reached.

Usage recommendations

Use coolant or cutting fluid for metal work to prolong tool life and reduce heat. For best results, secure thin sheet material with clamps or a backing plate to avoid deformation and ensure clean holes.
