## Summary description

Proline Tools 78008K is a set of five metal drill bits with 0.8 mm diameter and 30 mm overall length. Designed for precision drilling in metal and similar materials, the pack provides small-diameter bits suitable for model making, electronics, and fine mechanical work. Ideal for handheld or bench drills requiring fine holes.

## Long description

Proline Tools 78008K — 5 pieces, 0.8 mm diameter, 30 mm length is a set of five high-speed steel (HSS) cobalt drill bits designed for precision metalworking. Each bit has a 0.8 mm working diameter and a 30 mm overall length, ground for accuracy and straightness. The drills feature a 135° point angle with chamfering adjustment to facilitate rapid centering and reduce time spent on marking out. Made from HSS with 5% cobalt, these bits resist high temperatures and are intended for demanding materials including high-alloy, titanium, acid-resistant and stainless steels, creep-resisting steels, cast iron and other hard-to-machine metals.
Advantages
The drills are produced entirely by grinding, ensuring high dimensional accuracy and rectilinearity of holes. A 135° point angle combined with chamfering adjustment improves centering and chip evacuation for small-diameter work. Construction from highest-class HSS with 5% cobalt increases resistance to heat and wear, extending tool life when drilling hard alloys and stainless materials. The blister pack keeps the five bits organized and protected for storage and transport.
Suitable for
 Precision model making and miniatures
 Electronics and PCB drilling for component leads and vias
 Fine mechanical work and watchmaking repairs
 Handheld and benchtop drilling where small, accurate holes are required
Key specifications
 Quantity: 5 drill bits
 Diameter: 0.8 mm
 Overall length: 30 mm
 Material: high-speed steel (HSS) with 5% cobalt
 Point angle: 135° with chamfering adjustment
 Manufacturing method: fully ground flutes and tips for accuracy
 Suitable materials: high-alloy steels, titanium, acid-resistant and stainless steels, creep-resisting steels, cast iron and other hard-to-machine metals
How to use
Select an appropriate drill speed and feed for a 0.8 mm diameter HSS cobalt drill bit and secure the workpiece in a vice or jig to prevent movement. Use a center punch or pilot mark where possible to aid accurate positioning; the 135° point improves self-centering but a faint punch mark can reduce walking. Apply cutting fluid when drilling stainless, high-alloy or heat-sensitive materials to improve lubrication and reduce heat build-up. Start drilling at a low speed to establish the hole, then increase speed cautiously while maintaining steady, light feed pressure. Periodically withdraw the bit to clear chips and reapply cutting fluid as needed. After drilling, deburr the hole edges with a small file or deburring tool.
Usage recommendations
For best results when working with stainless and high-alloy steels, use moderate spindle speeds, constant lubrication, and light, consistent feed to minimize bit overheating and wear. Store bits in their blister pack to protect ground tips from damage.
