Twist drill bit Bosch HSS hex-shank 8 mm

Twist drill bit Bosch HSS hex-shank 8 mm is a high-strength metal-drilling bit designed for use with impact drivers and drills. Precision-ground from solid HSS with an oxide-coated flute, the 8 mm bit delivers reduced wear and reliable cutting performance. It is manufactured to DIN 338 as Type N with a 135° split-point tip and diameter tolerance h8, and features a 1/4-inch hex shank for secure, universal fit in tool chucks and quick-change holders.

Advantages

The HSS construction and oxide-coated flute increase durability and help reduce friction during drilling. The 135° split-point tip provides active cutting and precise centring to minimise walking at startup, while the h8 tolerance ensures consistent hole diameter. The 1/4-inch hex shank enables fast bit changes and stable engagement with impact drivers and drills.

Suitable for

• Drilling holes in steel and other metals
• Use with impact drivers and cordless drills
• Professional metalworking and general DIY metal drilling tasks

How to use

Secure the 1/4-inch hex shank in the drill or impact driver chuck. Select an appropriate rotational speed and apply steady pressure to let the bit cut without forcing. For metal drilling, use cutting fluid or coolant where appropriate to prolong bit life and maintain cutting performance. Withdraw the bit occasionally to clear chips when drilling deeper holes.

Usage recommendations

Use appropriate personal protective equipment (safety glasses and gloves) and clamp the workpiece securely. Match drill speed and feed to the material; reduce speed for harder metals and increase coolant flow for extended use.
