Twist Drill Bit Bosch HSS PointTeQ 8 mm

The Bosch HSS Twist Drill Bit PointTeQ 8 mm is a high-speed steel drill bit with a PointTeQ tip, designed for precision drilling in metal and general-purpose use in drill stands and handheld drill drivers. It features a cylindrical shank and comes in a single-blister package. The geometry and coating aim to improve drilling speed, chip evacuation, and tip durability for clean, controlled holes.

Advantages

The PointTeQ tip design increases drilling rate while reducing heat and wear, maintaining a sharp cutting edge for consistent performance. A black-oxide coated flute promotes fast chip removal, and the bit’s high elastic body reduces the risk of breakage, especially for smaller diameters. Manufactured to DIN 338 with a Type N flute angle and a 135° tip, the bit delivers reliable centering and stable drilling behavior.

Suitable for

• Drilling holes in metal sheets, profiles and common steels
• Use in drill stands for accurate, repeatable holes
• Handheld drill drivers for general workshop and DIY tasks

Key specifications

• Material: High-speed steel (HSS)
• Tip design: PointTeQ, 135° point angle
• Flute coating: Black oxide
• Flute type: Type N (standard flute angle)
• Shank type: Cylindrical
• Diameter: 8 mm
• Standards: Manufactured to DIN 338

How to use

Secure the drill bit in the chuck of a drill stand or handheld drill driver with the cylindrical shank fully seated and tightened. Select an appropriate speed and lubrication for the metal being drilled; start with moderate speed and apply steady pressure to allow the PointTeQ tip to center and cut. Clear chips regularly to maintain effective chip evacuation through the black-oxide flutes and avoid overheating. When drilling smaller diameters, use controlled feed to reduce flex and risk of breakage.

Usage recommendations

For best results when drilling metal, use cutting fluid or suitable lubricant, maintain moderate speeds to reduce heat buildup, and replace the bit if tip wear or chipping appears to preserve hole quality and tool safety.
