Drill bit Proline HSS-TiN 5.0 mm, 2 pcs

Two Proline HSS-TiN 5.0 mm drill bits supplied as a 2-piece set, designed for general workshop and maintenance tasks. Made from high-speed steel (HSS) with a titanium nitride (TiN) coating to increase surface hardness and extend tool life. Each bit has a 5.0 mm diameter, 52 mm working length and 86 mm overall length, and features a 135° split-point geometry with an adjustable margin for improved centring and reduced walking when drilling metal, wood and plastics.

Advantages

HSS construction combined with TiN coating increases wear resistance and maintains cutting performance for longer compared with uncoated bits. The 135° split-point reduces the need for pilot holes and improves initial bite, while the adjustable margin and ground flutes produce cleaner hole finishes. Supplied as a compact 2-piece set for easy storage and replacement.

Suitable for

• Drilling in metal (sheet metal, non-hardened steel)
• Drilling in wood (soft and hardwood)
• Drilling in plastics
• General workshop, maintenance and DIY tasks

How to use

Secure the appropriate drill bit in the chuck of a drill or drill press. Mark the drilling position and, if necessary, clamp the workpiece. Start at low speed to establish the hole and increase speed appropriate to the material being drilled. Apply steady pressure, withdraw occasionally to clear chips, and use cutting fluid when drilling metals to extend bit life and improve finish.

Usage recommendations

For best results on metal, use cutting oil and moderate speed; for wood and plastics, use higher speeds and minimal feed pressure to avoid melting or splintering. Replace bits once wear affects hole quality.
