## Summary description

The Bosch HSS Step Drill Bits feature a 3-flat shank design for secure grip and reduced slipping. Ideal for drilling in metal, these bits offer precision and durability. The step design allows for multiple hole sizes with a single bit, making it versatile for various applications. Perfect for professionals and DIY enthusiasts alike, these drill bits ensure clean and accurate holes every time.

## Long 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
Key specifications
 Material: HSS (high-speed steel)
 Shank: 3-flat shank for anti-slip and torque transmission
 Tip: Split-point for easy start without pre-punching
 Flute: CNC-ground spiral flute for chip removal and reduced vibration
 Marking: Laser-marked diameter figures in flutes
 Manufacturer part number (MPN): 2608587427
 EAN: 3165140630214
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.
