Drill bit set Proline 79214 — 13 pieces, assorted sizes

Proline 79214 — 13 pieces, assorted sizes is a compact drill bit set designed for general drilling tasks with handheld drills and drivers. The set includes thirteen HSS bits with ground edges and a 135° point angle with chamfering adjustment, offering stable cutting performance across common materials. The assortment covers multiple diameters to support repair, installation and DIY jobs where a range of hole sizes is required.

Advantages

The refined HSS material provides wear resistance and consistent cutting action. Ground edges ensure precise chip evacuation and reduced friction during drilling. The 135° point angle with chamfering adjustment enables fast penetration and improves centring for reduced walking on the workpiece. The assortment of sizes in one compact set reduces the need to change individual bits and keeps frequently used diameters accessible.

Suitable for

• Drilling holes in wood for furniture assembly and carpentry
• Drilling into plastics for household fixtures and enclosures
• Light to medium drilling in metal sheets and thin-walled components
• Maintenance, installation and general DIY tasks requiring multiple diameters

Key specifications

• Number of pieces: 13
• Material: refined high-speed steel (HSS)
• Tip geometry: 135° point angle with chamfering adjustment
• Edge finish: ground cutting edges
• Intended use: handheld drills and drill drivers

How to use

Select the appropriate bit size for the required hole diameter, secure the bit in the drill chuck and tighten firmly. Start drilling at low speed to establish a centre and then increase speed as needed for the material being drilled. For metal and harder plastics, apply steady pressure and use cutting or cooling lubricant if required; for wood, moderate speed and steady feed produce cleaner holes. After use, inspect the cutting edges for wear and replace bits that show significant dulling or damage.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and feed to the material: lower speeds for metal and harder plastics, higher speeds for softwoods. Keep bits clean and store the set in a dry place to prevent corrosion and maintain cutting performance.
