## Summary description

Proline drill bit model 79105K, single metal drill bit with a 10.5 mm diameter and 133 mm length. Designed for drilling metal and similar materials; supplied as one piece. Suitable for workshop, repair and construction tasks where a medium-diameter metal drill is required and compatible with standard drill chucks.

## Long description

Proline 10.5 mm drill bit, model 79105K, single HSS metal drill with a working length of 133 mm designed for drilling through a variety of metals and similar materials. The bit features a 135° point angle with chamfering adjustment for fast penetration and reduced walking at the start of drilling. Ground cutting edges and refined high-speed steel construction provide consistent cutting performance and wear resistance. Supplied as one piece in a blister pack suitable for standard drill chucks commonly used in workshops, repair tasks and construction applications.
Advantages
The 135° point geometry with chamfering reduces the need for centre punching and improves start-up accuracy, while the ground edges ensure stable chip formation and efficient material removal. Refined HSS material balances hardness and toughness for longer life under intermittent and continuous use. The 133 mm length offers deeper reach than standard short bits while remaining compatible with most handheld and bench drill chucks.
Suitable for
Drilling holes in mild steel, sheet metal and other metallic materials
Workshop repair and maintenance tasks
Construction and installation work requiring medium-diameter metal holes
Use with handheld drills, drill presses and bench drills with standard chucks
Key specifications
Diameter: 10.5 mm
Overall working length: 133 mm
Point angle: 135° with chamfering adjustment
Material: refined high-speed steel (HSS)
Cutting edge: ground
Package: single piece in blister pack
How to use
Secure the drill bit firmly in the drill chuck ensuring correct centring and runout below manufacturer limits. Select an appropriate spindle speed for the material and diameter, and apply cutting lubricant when drilling steel or other hard metals to extend tool life and improve chip evacuation. Begin drilling at low speed to establish the hole, then increase speed and apply steady feed pressure appropriate to the drill and workpiece. Periodically withdraw the bit to clear chips when drilling deep holes.
Usage recommendations
For best results when drilling metal, use cutting oil and moderate speeds to reduce heat build-up; avoid excessive feed force to prevent premature wear or breakage. Inspect the ground cutting edges before use and replace the bit when wear degrades performance.
