## Summary description

Proline 78015K is a set of five metal drill bits with 1.5 mm diameter and 43 mm length. Designed for drilling metals and similar materials, the pack contains 5 precision bits for small-diameter holes. Suitable for workshop tasks, model making, electronics and light fabrication where narrow, accurate holes are required.

## Long description

Proline 78015K is a set of five precision metal drill bits with a nominal diameter of 1.5 mm and a length of 43 mm. Manufactured from high-speed steel with 5% cobalt (HSS-Co), these bits are designed for drilling small, accurate holes in metals and other hard-to-machine materials. Each drill is fully ground to ensure straightness and dimensional accuracy and is supplied in a blister pack for safe storage and handling.
Advantages
The 135° point angle with chamfering adjustment enables fast penetration and reliable centring on metal surfaces, reducing the need for re-marking. HSS steel with 5% cobalt provides increased heat resistance and extended tool life when working with high-alloy, stainless, acid-resistant, and creep-resisting steels, titanium and cast iron. Precision grinding of the flutes and cutting edges ensures consistent hole quality and rectilinearity for repeatable, small-diameter drilling.
Suitable for
Workshop drilling of thin metal sheets and small parts
Model making and scale prototypes
Electronics and PCB work requiring narrow vias and component holes
Light fabrication and repair tasks with hard-to-machine alloys
Precision hobby applications and fine mechanical assembly
Key specifications
Set contents: 5 drill bits, each 1.5 mm diameter, 43 mm overall length
Material: high-speed steel with 5% cobalt (HSS-Co)
Point angle: 135° with chamfering adjustment
Manufacturing method: fully ground drills for high straightness and accuracy
Temperature resistance suitable for high-speed and intermittent cutting in hard alloys
Suitable for: high-alloy steels, stainless and acid-resistant steels, titanium, cast iron and other difficult-to-machine materials
Packaging: blister pack for each set
How to use
Secure the workpiece and use an appropriate clamping method to prevent rotation or movement. Select the correct drill speed for 1.5 mm HSS-Co drills—moderate to high spindle speeds with controlled feed produce the best results. Where possible, centre-punch or use a pilot mark to improve initial tracking, especially on smooth or hardened surfaces. Apply cutting fluid to reduce friction and temperature build-up when drilling hard alloys; peck drilling is recommended for deeper holes to clear chips and avoid tool breakage. After use, clean and store the bits in their blister pack to protect cutting edges.
Usage recommendations
Use moderate speeds and steady feed rates with adequate cooling when drilling stainless, high-alloy steels or titanium. For small-diameter holes, maintain alignment and avoid side loads to prevent chipping or breakage; replace worn drills to ensure hole quality and dimensional accuracy.
