Drill bit set Proline CTi universal 5 pcs 4–10 mm

Proline CTi universal 5-piece drill bit set contains five carbon‑titanium coated bits with diameters 4 mm, 5 mm, 6 mm, 8 mm and 10 mm. The set is designed for general drilling tasks across a range of materials and comes as a compact selection suitable for common repair and construction needs.

Advantages

The carbon‑titanium coating increases bit hardness and wear resistance compared with uncoated steel, extending tool life during repeated use. A range of diameters in one set reduces the need to buy individual bits and covers typical hole sizes for metal, wood and plastic. The bits are compatible with standard drill chucks and are supplied as a ready set for immediate use.

Suitable for

• Drilling holes in metal sheets and mild steel
• Woodworking and carpentry tasks
• Drilling plastic and composite materials
• General DIY repairs and maintenance

How to use

Select the drill bit with the required diameter, secure it in the drill chuck and tighten according to the drill manufacturer’s instructions. Start drilling at low speed to create a guide point, then increase speed and apply steady pressure appropriate to the material. Use cutting fluid or coolant when drilling metals to reduce heat and prolong bit life. After use, clean the bits and store them dry to prevent corrosion.

Usage recommendations

For best results, match drill speed and feed pressure to the material being drilled: lower speeds for metals, higher speeds for wood and plastics. Inspect bits for wear before use and replace if chipped or excessively worn.
