## Summary description

Proline 79052K metal drill bit with a 5.2 mm diameter and 86 mm overall length.

## Long description

Proline 5.2 mm drill bit, model 79052K, is a single high-speed steel (HSS) straight shank bit with an overall length of 86 mm, designed for making precise 5.2 mm holes in metal and other hard materials. The bit features ground cutting edges and a 135° point angle with chamfering adjustment to reduce walking on the workpiece and speed up centring. Packaged as a single unit in a blister pack, this Proline drill bit is suitable for use with handheld drills and drill presses in repair, fabrication and workshop environments.
Advantages
The refined HSS material provides durability and heat resistance for repeated metal drilling. Ground edges ensure clean, accurate cuts and improved chip evacuation. The 135° point angle with chamfering adjustment reduces the need for extensive centre punching and helps maintain hole position, while the straight shank enables secure clamping in standard drill chucks. Supplied in a blister pack that protects the cutting surface during storage and transport.
Suitable for
Drilling through steel and non-ferrous metals
General workshop and fabrication tasks
Repair and maintenance work with handheld drills or drill presses
Creating 5.2 mm clearance or pilot holes for fasteners
Key specifications
Cutting diameter: 5.2 mm
Overall length: 86 mm
Point angle: 135° with chamfering adjustment
Material: refined high-speed steel (HSS)
Shank type: straight shank for standard drill chucks
Edge finish: ground cutting edges
Packaging: single piece in blister pack
How to use
Clamp the drill bit securely in the chuck so the shank is seated straight and tight. Select an appropriate drill speed for the workpiece material—moderate speeds for mild steel and lower speeds for hardened metals—and apply steady feed pressure. Use cutting fluid or coolant when drilling metal to reduce heat, prolong tool life and improve chip evacuation. If precise hole location is required, make a light centre punch or use the chamfering adjustment to help start the cut before full drilling.
Usage recommendations
For best results, use coolant during continuous drilling in metal and replace the bit when wear or chipping of the cutting edges is evident. Match drill speed and feed to material hardness and ensure the workpiece is securely clamped to prevent movement and improve hole accuracy.
