Drill Bit Proline HSS-TiN 6.5 mm – metal and wood drilling

Proline HSS-TiN 6.5 mm drill bit made of high-speed steel with a titanium nitride (TiN) coating designed for drilling metal and wood. The bit features a 135° split-point geometry with adjustable web thinning to improve centring and reduce walking. Diameters and lengths: diameter 6.5 mm, working length 63 mm, overall length 101 mm.

Advantages

The TiN coating increases wear resistance and prolongs tool life compared with uncoated HSS bits while providing improved hole finish. The 135° split-point with sloping web adjustment reduces walking at the drill start and lowers the force required for penetration, making it suitable for both hand drills and drill presses. The bit is ground to precise tolerances for consistent hole size and accuracy.

Suitable for

• Drilling steel and non-ferrous metals
• Drilling wood and plywood
• General workshop repairs and DIY projects
• Use with hand drills and drill presses

Key specifications

• Diameter: 6.5 mm
• Working length: 63 mm
• Overall length: 101 mm
• Material: HSS (high-speed steel)
• Coating: Titanium nitride (TiN)
• Point angle / geometry: 135° split point with web thinning adjustment

How to use

Clamp the workpiece securely and select an appropriate drill speed for the material (lower speeds for harder metals, higher speeds for wood). Use a centre punch for accurate starting position in metal where required. Start drilling with steady, moderate pressure; allow the drill bit to cut and withdraw occasionally to clear chips when drilling deep holes. For prolonged life, avoid excessive heat by using cutting fluid for metal drilling and moderate speeds.

Usage recommendations

For best results when drilling metal, use cutting oil and apply moderate speed; for wood, use higher speeds and ensure chip clearance. Store the bit dry to protect the TiN coating and inspect for wear before precision operations.
