Kierukkaporasarja Bosch HSS 2608587013

Twist Drill Bit Set Bosch HSS 2608587013 contains 19 ground HSS twist drill bits designed for drilling into steel and cast iron. Manufactured to DIN 338, each bit is Type N with a 135° tip and diameter tolerance h8. The bits have a cylindrical shank equal to the drill diameter and are suitable for use in drill stands and portable drill drivers.

Advantages

Precision-ground high-speed steel (HSS) ensures fast, accurate drilling and longer tool life. The 135° tip reduces walking and improves centring, and the DIN 338 specification with h8 tolerance guarantees consistent diameters. For holes up to 10 mm diameter, pre-punching or pilot drilling is not required, which saves time on standard metal-working tasks.

Suitable for

• Drilling steel
• Drilling cast iron
• Workshop and maintenance tasks
• Home DIY projects requiring metal drilling

How to use

Secure the appropriate bit in the chuck of a drill stand or hand drill. Use suitable cutting speed and lubrication for the metal being drilled to extend bit life. For holes with diameter up to 10 mm, drilling can begin directly without pilot holes; for larger diameters or hard materials, consider pilot drilling. Apply steady axial pressure and clear chips regularly to avoid overheating.

Recommendations

Use cutting oil when drilling steel or cast iron to reduce heat and increase tool life. Inspect bits for wear or damage before use and replace if the tip is blunted or chipped.
