## Summary description

Bosch HSS Step Drill Bits 2608587428 feature a 3-flat shank for secure grip and stability. Ideal for drilling holes in metal, wood, and plastic. Durable HSS construction ensures longevity and precision in drilling.

## Long description

Bosch HSS Step Drill Bits 2608587428 feature a stepped cutting profile that allows drilling multiple hole diameters with a single bit. Made of high-speed steel (HSS) with laser-marked diameter graduations in the spiral flutes, this step drill bit is designed for smooth, burr-free holemaking and enlarging existing holes in thin materials. The split-point tip eliminates the need for pre-punching, while CNC-ground spiral flutes and axial/radial relief grinding improve chip removal, reduce vibration and provide consistent cutting performance. The 3-flat shank prevents slipping in the chuck and enables reliable torque transmission.
Advantages
The HSS construction offers long tool life when used with coolant, and the split-point tip provides accurate centring and easy starts. CNC-ground spiral flutes optimise chip evacuation and reduce vibration for even drilling. Laser-etched diameter markings in the flutes ensure visible, durable measurement reference. The 3-flat shank increases grip in the chuck and supports high-torque applications without slippage.
Suitable for
Drilling and enlarging holes in non-ferrous metals (e.g., aluminium)
Working with sheet steel and stainless steel
Cutting holes in plastics and sheet plastic
Applications requiring multiple hole diameters without tool changes
Key specifications
Brand: Bosch
MPN: 2608587428
EAN: 3165140630221
Material: High-speed steel (HSS)
Shank: 3-flat shank for anti-slip and torque transmission
Tip: Split-point tip for easy start and no pre-punching
Flutes: CNC-ground spiral flutes with laser-marked diameter graduations
How to use
Secure the step drill bit in the drill chuck using the 3-flat shank to prevent slipping. Select appropriate speed and coolant for the material being cut (lower speeds for stainless steel, use cutting fluid for metal). Start drilling with light pressure to allow the split-point tip to centre, then increase feed steadily. For enlarging existing holes, align the bit concentrically and advance gradually through the required steps. Retract occasionally to clear chips if needed.
Usage recommendations
Use cutting fluid when drilling metals to extend tool life and improve surface finish. Match drill speed to material hardness and avoid excessive side load; the bit is optimised for thin materials such as sheet metal and plastics rather than thick solid stock.
