## Summary description

Set of three Proline HSS‑TiN drill bits with 3.0 mm diameter designed for metalworking and general drilling tasks. High-speed steel construction with titanium nitride (TiN) coating increases wear resistance and reduces friction. Suitable for portable drills and drill presses; offers consistent hole quality and longer tool life for DIY, maintenance, and workshop use.

## Long description

Set of three Proline HSS‑TiN drill bits with 3.0 mm diameter designed for metalworking and general drilling tasks. Each drill has a 135° split point with adjustable chisel angle for improved centring and reduced walking. Bits are ground and coated with titanium nitride (TiN) to increase wear resistance and improve hole finish. Working length 33 mm, overall length 61 mm.
Advantages
High-speed steel (HSS) core provides toughness for metal drilling while the TiN coating reduces friction and extends service life. The 135° split-point geometry enhances centre accuracy and penetration on metal surfaces. Ground flutes ensure consistent chip evacuation and better surface quality of holes.
Suitable for
 Drilling in metal (steel, aluminium, non‑ferrous alloys)
 Portable drills and drill presses
 Workshop, maintenance and DIY tasks requiring precise small-diameter holes

How to use
Secure the appropriate drill bit in the chuck of a portable drill or drill press. Mark the drilling point and, if necessary, use a centre punch to prevent walking. Use suitable cutting speed and feed for the metal being drilled; apply steady pressure and keep the drill perpendicular to the surface. Periodically withdraw the bit to clear chips and prevent overheating. For best results, use cutting fluid when drilling tougher metals.
Usage recommendations
Use appropriate drill speeds and cooling for the material: lower speeds and cutting fluid for hardened steels, moderate speeds for aluminium and softer alloys. Inspect TiN coating for wear and replace bits when performance or hole quality deteriorates.
