## Summary description

Proline 79125K metal drill bit with a diameter of 12.5 mm and overall length 151 mm. Sold as a single piece, this straight-shank drill is intended for drilling metal and similar hard materials. Suitable for use with compatible drill chucks in workshop, maintenance and construction tasks where a single large-diameter hole is required.

## Long description

Proline 79125K metal drill bit has a 12.5 mm diameter and an overall length of 151 mm. Manufactured from refined high-speed steel (HSS) with ground cutting edges and a 135° point angle with chamfering adjustment, this straight-shank drill is designed for drilling metal and other hard materials. The single-piece packaging and robust construction make it suitable for workshop, maintenance and construction tasks where a single large-diameter hole is required and compatible with standard drill chucks.
Advantages
The refined HSS material and precisely ground edges provide consistent cutting performance and extended tool life when drilling metals. The 135° point angle with chamfering adjustment supports quick entry and reduces the need for extensive centre punching, improving drilling accuracy and saving time. The straight shank design ensures secure clamping in most drill chucks and minimizes runout for cleaner holes.
Suitable for
 Drilling holes in ferrous and non-ferrous metals
 Workshop and maintenance repairs
 Construction tasks requiring a single large-diameter hole
 Use with corded and cordless drills with compatible chucks
Key specifications
 Diameter: 12.5 mm
 Overall length: 151 mm
 Material: refined high-speed steel (HSS)
 Point angle: 135° with chamfering adjustment
 Cutting: ground edges for improved accuracy
 Shank type: straight shank
 Package quantity: 1 piece
How to use
Secure the drill bit in a compatible drill chuck, ensuring the shank is fully seated and the chuck is tightened to prevent slipping. Mark the drilling position and, if necessary, use a centre punch to create a shallow dimple for improved accuracy. Start drilling at low speed to establish the hole, apply steady pressure without forcing the bit, and increase speed as appropriate for the material being drilled. Use cutting fluid or oil when working with metals to reduce heat, improve lubrication and extend bit life. After completing the hole, withdraw the bit slowly while the drill is still turning to clear chips safely.
Usage recommendations
For best results when drilling metal, use cutting fluid, maintain moderate drilling speed suited to the material thickness, and avoid excessive side loads. Replace the bit if wear or chipping of cutting edges is visible to preserve hole quality and reduce the risk of breakage.
