Pointed chisel drill bit Bosch HSS Twist Drill Bit PointTeQ Sey

The Bosch HSS Twist Drill Bit PointTeQ Sey is a set of five HSS metal drill bits with a hex shank, designed for precise and efficient drilling in metal. Each bit features a split-point self-centring tip and a black-oxide-coated flute for improved chip evacuation and reduced friction. Conforming to DIN 338 Type N with a 135° tip angle, these bits are intended for professional and hobby use where durable, accurate metal drilling is required.

Advantages

Self-centring split-point tip prevents walking and enables quick drill starts while active cutting reduces the need for pilot holes. The black-oxide-coated flute promotes faster chip removal and lowers friction during drilling. The hex shank provides a secure connection to chucks and bit holders and reinforces the bit body to reduce the risk of breakage. Manufactured to DIN 338 Type N standards for consistent geometry and performance.

Suitable for

• Drilling holes in steel and other metals
• Workshop and construction tasks requiring precise metal holes
• Use with hand drills and drill drivers with hex chucks or bit adapters
• Professional tradespeople and serious DIY projects

How to use

Secure the appropriate bit in a compatible hex chuck or adapter and clamp the workpiece. Start drilling at low speed to engage the self-centring tip, then increase speed as the bit cuts steadily. Apply steady, moderate pressure and clear chips frequently to avoid overheating. Use cutting fluid on harder metals to extend bit life and maintain cutting performance.

Recommendations

For best results when drilling metal, use a drill with adjustable speed, keep the bit cool with intermittent drilling or cutting fluid, and replace bits that show significant wear or rounding of the tip.
