## Summary description

Single Proline drill bit model 77150 for metalworking, diameter 15 mm and overall length 169 mm. Designed for drilling holes in metal surfaces, this solid drill bit suits workshop and repair tasks where a medium-large diameter is required. Supplied as one piece and compatible with standard drill chucks for manual and machine use.

## Long description

Proline 77150 is a single HSS metal drill bit with a 15 mm diameter and an overall length of 169 mm, supplied as one piece. Designed for metalworking, this solid, fully ground drill bit fits standard drill chucks for both manual and machine use. Its 135° point angle with chamfering adjustment and precision grinding ensure straight, accurate holes and efficient cutting performance for workshop and repair tasks that require a medium-large diameter.
Advantages
The drill bit is made entirely by precision grinding from high-quality refined high-speed steel (HSS), which provides increased abrasion resistance, resilience and torsional strength. The 135° point geometry with chamfering adjustment allows quick penetration and reduces the need for repeated centre punching. Fully ground construction guarantees high dimensional accuracy and straightness of drilled holes, improving efficiency compared with conventional cylindrical drills.
Suitable for
Drilling holes in steel and other ferrous metals
Workshop and maintenance tasks requiring a 15 mm hole
Use in hand-held drills and drill presses with compatible chucks
Repair, fabrication and metalworking projects

Point angle: 135° with chamfering adjustment
Manufacturing: fully ground flute and body for precision
Characteristics: increased abrasion resistance, enhanced resilience and torsional strength

How to use
Secure the drill bit in a suitable chuck, ensuring it is correctly seated and tightened. Select an appropriate cutting speed and feed for the metal being drilled; use lower speeds for harder materials and higher speeds for softer metals. Apply steady, even pressure and allow the drill bit to cut without forcing. Periodically withdraw the bit to clear chips and improve cooling. For cleaner starts, use a centre punch or pilot mark if necessary, although the 135° point reduces the need for extensive centre punching.
Usage recommendations
Use cutting fluid or suitable lubricant when drilling metals to reduce heat build-up and extend tool life. Inspect the drill bit for wear or damage before use and replace when cutting performance declines. Match the drill speed and feed to the metal type and thickness to ensure accurate holes and longer tool life.
