## Summary description

Proline 78065K metal drill bit with a 6.5 mm diameter and 101 mm overall length. Supplied as a single piece, this drill bit is designed for drilling metal and similar materials with drills or drill presses. Suitable for workshop and maintenance tasks where a mid‑sized, general-purpose metal cutting bit is required.

## Long description

Proline 78065K metal drill bit, diameter 6.5 mm and overall length 101 mm, is a single-piece HSS-Co cutting tool designed for drilling a wide range of metals. Manufactured from high-class high-speed steel with 5% cobalt and produced entirely by grinding, this drill bit delivers precise, straight holes and high dimensional accuracy. The 135° point angle with chamfering adjustment facilitates fast penetration and reduced walking during start-up, while elevated temperature resistance supports use at higher cutting speeds and in demanding materials.
Advantages
This Proline drill bit offers enhanced wear resistance and durability due to its cobalt alloyed HSS composition, making it suitable for hard and heat-resistant steels, stainless and acid-resistant alloys, titanium, and cast iron. Fully ground flutes ensure good concentricity and straightness of drilled holes. The 135° split-point geometry reduces the need for center punching and improves centering, which saves time during marking and setup. Supplied as a single piece in a blister pack, it is ready for workshop or maintenance use.
Suitable for
 Drilling holes in high-alloy and stainless steels
 Workshop maintenance and repair tasks
 Drilling in titanium and acid-resistant materials
 Use with hand drills and drill presses for medium-sized holes

How to use
Secure the Proline 78065K drill bit in the appropriate chuck of a hand drill or drill press, ensuring correct clamping and concentricity. Select a suitable cutting speed and feed for the workpiece material; lower speeds are recommended for stainless and heat-resistant steels while higher speeds may be used for softer steels within the drill’s thermal limits. Use cutting fluid or coolant when drilling hard, heat-sensitive, or stainless materials to extend tool life and improve chip evacuation. Apply moderate pressure and allow the drill to cut steadily without excessive force.
Usage recommendations
For best results when drilling high-alloy or stainless steels, pre-drill pilot holes for larger diameters, maintain proper coolant flow, and avoid overheating by using intermittent drilling or pecking cycles. Replace the bit when wear or chipping affects hole quality.
