## Summary description

Cylindrical HSS drill bit by GRAPHITE, 3.8 mm diameter (model 55H017), designed for drilling metal. Made from high-speed steel for wear resistance and heat tolerance during metalworking. Suitable for hand drills and drill presses when creating precision holes in steel, iron and non-ferrous metals in maintenance, fabrication and hobby projects.

## Long description

GRAPHITE cylindrical HSS drill bit, 3.8 mm diameter (model 55H017), is engineered for drilling metal with precision. Made from high-speed steel, the bit offers wear resistance and improved heat tolerance under typical metalworking conditions. Its cylindrical shank fits standard chucks on hand drills and drill presses, enabling accurate hole making in steel, iron and non-ferrous metals for maintenance, fabrication and hobby tasks.
Advantages
The high-speed steel construction provides durable cutting performance and resistance to softening at elevated temperatures. The cylindrical shank ensures secure clamping in most drill chucks and contributes to consistent concentricity during drilling. The 3.8 mm diameter is suitable for creating small accurate holes while minimising material stress. The tool’s geometry balances cutting speed and chip evacuation for general-purpose metal drilling.
Suitable for
Drilling through mild steel and cast iron for maintenance and repair
Piercing non-ferrous metals such as aluminium, brass and copper
Fabrication and light manufacturing tasks requiring precise small-diameter holes
Hobby and DIY metalworking projects
Use with hand drills and drill presses for bench and on-site work
Key specifications
Material: high-speed steel (HSS) for cutting performance and heat resistance
Shank type: cylindrical shank compatible with standard drill chucks
Diameter: 3.8 mm for small-diameter precise holes
Suitable materials: steel, cast iron, aluminium, brass, copper and other non-ferrous metals
Typical applications: maintenance, fabrication, hobby metalworking
How to use
Select an appropriate drill speed for the metal being drilled and secure the workpiece to prevent movement. Mount the cylindrical shank in the drill chuck and ensure it is firmly clamped and concentric. Use cutting fluid or lubricant when drilling ferrous metals to reduce heat and extend tool life. Apply steady, moderate feed pressure; do not force the bit. Withdraw periodically to clear chips when drilling deeper holes, and finish with reduced speed for a cleaner hole edge.
Usage recommendations
For best results, match drill speed to the material hardness: lower speeds for harder steels and higher speeds for softer non-ferrous metals. Use cutting fluid for prolonged drilling in steel and iron, and replace the bit if wear or chipping appears to maintain hole accuracy.
