## Summary description

Single metal drill bit Proline 79075K with a 7.5 mm diameter and 109 mm length. Designed for metal drilling tasks, this single-piece bit provides standard straight-shank compatibility with hand drills and drill presses.

## Long description

Single metal drill bit Proline 79075K with a 7.5 mm diameter and 109 mm overall length. Manufactured from refined high-speed steel (HSS) with ground cutting edges and a 135° point angle featuring chamfering adjustment for faster centering and reduced walking. The straight shank fits standard hand drills and drill presses, making this single-piece bit suitable for common metalworking, maintenance, and repair tasks that require a precise 7.5 mm hole.
Advantages
The HSS construction delivers wear resistance and thermal stability during continuous drilling in metal. The 135° point angle with chamfering adjustment improves centring and starts holes quickly, reducing the need for prolonged centre punching. Precisely ground edges ensure clean, accurate holes and extended cutting life under normal operating speeds. The straight shank design provides compatibility with a wide range of drills and chucks.
Suitable for
Drilling through mild and alloy steels
Maintenance and repair work on metal components
Workshop tasks with hand drills or drill presses
Creating 7.5 mm diameter holes for fasteners or fittings
Key specifications
Diameter: 7.5 mm
Overall length: 109 mm
Material: refined high-speed steel (HSS)
Point angle: 135° with chamfering adjustment
Shank type: straight shank
Cutting edges: precision ground
How to use
Secure the drill bit in the chuck so it is firmly seated and concentric. Mark the drilling location and, if necessary, create a small centre punch mark to help guide the bit. Use appropriate cutting speed and steady feed pressure for metal drilling; apply cutting fluid or coolant when drilling harder alloys or during prolonged cuts to reduce heat and extend tool life. Withdraw periodically to clear chips and prevent clogging. After use, clean and lightly oil the bit to protect the HSS surface.
Usage recommendations
For best results in steel, use moderate spindle speeds and steady feed, and employ cutting fluid for improved cooling and chip evacuation. Avoid excessive pressure that can cause overheating or premature wear.
