Drill bit set Proline 79213 — 13 pieces

Proline 79213 — 13 pieces is a drill bit set made for general drilling tasks. The kit includes thirteen high-speed steel (HSS) bits with ground edges and a 135° point angle with chamfering adjustment to enable fast, accurate starts and reduced walking during centre punching. The set is compatible with standard hand drills and drill drivers and covers a range of common diameters used in home repair, workshop and construction tasks.

Advantages

The HSS material provides good hardness and heat resistance for routine metal and wood drilling. Ground cutting edges offer consistent performance and smoother holes. The 135° point angle with chamfering adjustment improves centring and reduces the need for additional pilot holes, enabling quicker drilling. The set format with multiple sizes ensures versatility for varied projects.

Suitable for

• Drilling holes in metal and thin sheet steel
• Wood drilling for general carpentry and repairs
• Plastic and composite material drilling
• Routine home maintenance and workshop tasks

Key specifications

• Number of pieces: 13
• Material: refined high-speed steel (HSS)
• Point angle: 135° with chamfering adjustment
• Cutting edges: ground
• Intended use: compatible with standard hand drills and drill drivers for metal, wood and plastics

How to use

Select the appropriate drill bit size for the required hole diameter and secure it in the drill chuck. Mark the drilling position and, when precision is important, use a centre punch or the chamfering adjustment to create a small indentation. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material. Use steady pressure, withdraw occasionally to clear chips, and allow the bit to cool when drilling hard materials.

Usage recommendations

For best results when drilling metal, use cutting fluid or lubricant to reduce heat and extend bit life. When drilling wood or plastics, clear chips frequently to avoid melting or splintering. Inspect bits regularly for wear and replace any with blunted or damaged edges to maintain accurate drilling.
