## Summary description

Proline 78060K metal drill bit, single-piece set with 6 mm working diameter and 93 mm overall length. Designed for drilling metal and other hard materials; compatible with standard drill chucks. Suitable for repair, metalworking and construction tasks requiring precise 6 mm holes. Sold as 1 piece.

## Long description

The Proline 78060K metal drill bit is a single-piece HSS-Co drill designed for creating precise 6 mm diameter holes. With a total length of 93 mm and a 135° point angle with chamfering adjustment, this drill bit is intended for use on metal and other hard-to-machine materials. Manufactured by grinding from high-class high-speed steel with 5% cobalt, the bit offers elevated temperature resistance and consistent geometry for accurate, straight holes. It is supplied in a blister pack as a single piece and fits standard drill chucks for general repair, metalworking and construction tasks that require a reliable 6 mm hole.
Advantages
The 135° point angle with chamfering adjustment allows quick centring and reduced walking at the drill tip, improving drilling speed and repeatability. Construction from HSS with 5% cobalt increases heat resistance and cutting performance when working with high-alloy steels, stainless steels, titanium and cast iron. Full grinding production ensures high dimensional accuracy and rectilinearity of holes, while compatibility with standard chucks makes the bit easy to install and use in common drills.
Suitable for (tasks / use cases)
Drilling precise 6 mm holes in high-alloy and stainless steels
Work on titanium and acid-resistant metals in repair and fabrication
Construction and installation tasks requiring accurate metal holes
Metalworking and machining of cast iron and other hard materials
General maintenance and repair where a single 6 mm drill is needed
Key specifications
Working diameter: 6 mm
Total length: 93 mm
Point angle: 135° with chamfering adjustment
Material: high-speed steel with 5% cobalt (HSS-Co)
Manufacturing method: fully ground for high accuracy
Temperature resistance: enhanced for high-speed and heavy-duty drilling
Pack type: single-piece blister pack
How to use
Fit the drill bit securely into a compatible chuck and tighten according to the drill manufacturer’s instructions. Select appropriate rotational speed and feed rate for the workpiece material — lower speeds for hard alloys and stainless steel, higher speeds for softer metals. Use a centre punch or pilot mark to prevent walking, and apply steady pressure, letting the bit cut without excessive force. Use cutting fluid or coolant when drilling stainless steel, titanium or other heat-sensitive materials to extend tool life and improve hole quality. After use, clean the bit and store it dry to prevent corrosion.
Usage recommendations
For best results when drilling high-alloy or stainless materials, use cutting fluid and reduced spindle speed; for cast iron, a slightly higher speed and intermittent feed can improve chip evacuation. Replace the bit when wear or loss of geometry reduces hole quality.
