Twist drill bit Bosch HSS hex-shank 1 cm

Twist drill bit Bosch HSS hex-shank 1 cm is a high-strength HSS drill designed for precise drilling in metal and wood. The 1 cm diameter drill features a 1/4-inch hex shank for secure, slip-resistant mounting in impact drivers and standard chucks. The bit is precision-ground from solid metal with an oxide-coated flute and a 135° split-point tip for improved centring and reduced wear.

Advantages

The drill bit is manufactured to DIN 338, type N flute geometry, and packed with diameter tolerance h8 for consistent hole size. The oxide-coated flute lowers friction and wear while the precision-ground body ensures straightness and accuracy. The 135-degree split-point and pointed cutting edges provide active cutting and fast penetration without the need for pre-centring. The 1/4-inch hex shank enables universal use in impact drivers and quick-change chucks.

Suitable for

• Drilling holes in metal sheets, steel and non-ferrous metals
• Drilling in wood and general-purpose workshop tasks
• Use with impact drivers and drills with 1/4-inch hex chucks

How to use

Secure the 1/4-inch hex shank in the drill or impact driver chuck. Select an appropriate speed for the material: higher speeds for wood, medium to lower speeds for metals. Apply steady pressure and allow the split-point tip to self-centre; avoid excessive force that can overheat the bit. Retract periodically when drilling deep holes to remove chips and reduce heat buildup.

Usage recommendations

Use cutting lubricant when drilling hardened steels or prolonged metal drilling to extend bit life. Store the drill bit in its blister pack or a dedicated holder to protect the tip and maintain accuracy.
