## Long description

Set of three Proline HSS‑TiN drill bits with 3.5 mm diameter, designed for drilling in metal and wood. Made from high-speed steel with a titanium nitride (TiN) coating that increases surface hardness and wear resistance. Each bit has a working length of 39 mm and a total length of 70 mm, and features a 135° split-point angle with adjustable chisel edge for improved centring and reduced walking.
Advantages
The TiN coating improves drill life and maintains cutting performance over repeated use. The 135° split-point geometry with chisel edge adjustment reduces the need for pilot drilling and helps achieve cleaner holes in metal and wood. Compact set of three bits covers common repair and installation tasks and is compatible with standard hand drills and drill presses.
Suitable for
 Drilling holes in metal sheets and profiles

How to use
Clamp the workpiece securely and mark the drilling position. Install the 3.5 mm Proline HSS‑TiN bit in the drill chuck and tighten. Use appropriate drill speed for the material: slower speeds for metal, higher speeds for wood. Apply steady pressure without forcing the bit; allow the drill to remove material. Withdraw the bit periodically to clear chips when drilling deep holes.
Usage recommendations
For longer tool life and better hole quality, use cutting fluid when drilling metal, select a lower RPM, and avoid lateral forces. Store the bits in a dry place to protect the TiN coating.
