## Summary description

Proline 78010K is a set of five metal drill bits designed for precision drilling. Each bit has a diameter of 1 mm and a length of 34 mm, suitable for metalworking and fine-detail tasks such as electronics, jewelry, and model making. The set supplies multiple identical bits for repeatable small-diameter holes and tool replacement.

## Long description

Proline 78010K is a set of five precision metal drill bits with a diameter of 1 mm and a length of 34 mm. Manufactured from high-speed steel (HSS) with 5% cobalt, each bit is fully ground to ensure high accuracy and straightness of holes. The 135° point angle with chamfering adjustment supports fast penetration and accurate positioning, while the material composition provides improved temperature resistance and durability for demanding metalworking tasks.
Advantages
The bits are made entirely by grinding to deliver consistent concentricity and rectilinearity, reducing wobble and improving repeatability for small-diameter holes. The 5% cobalt HSS alloy increases hardness and heat resistance compared with standard HSS, making these bits suitable for machining high-alloy steels, titanium, stainless and acid-resistant steels, creep-resisting steels and cast iron. The 135° point geometry with chamfering aids quick drilling and reduces the need for extensive marking out.
Suitable for
Precision metal drilling in electronics and small assemblies
Jewellery making and watch repair
Model making and miniature fabrication
Replacement of worn small-diameter bits in workshop toolkits
Drilling in high-alloy and difficult-to-machine steels and cast iron
Key specifications
Quantity: 5 pieces
Diameter: 1 mm
Length: 34 mm (overall)
Material: High-speed steel (HSS) with 5% cobalt
Point angle: 135° with chamfering adjustment
Manufacturing: Fully ground flutes for accuracy and straightness
Temperature resistance: enhanced for high-speed and intermittent drilling
How to use
Select a drill press or handheld rotary tool compatible with 1 mm diameter bits and secure the workpiece to prevent movement. Mark the drilling position and, if needed, use a center punch to improve accuracy. Fit the bit into the chuck, ensure it is clamped straight and run the tool at an appropriate speed for small HSS-cobalt drills—typically higher spindle speeds with light feed and steady coolant or cutting lubricant. Apply light, consistent pressure; retract periodically to clear chips and avoid overheating. Replace bits from the set when wear affects hole quality.
Usage recommendations
For best results when drilling high-alloy or stainless materials, use cutting fluid and moderate speeds, avoid excessive feed force, and frequently clear chips. Store the bits in their blister pack to protect cutting edges and maintain accuracy.
