## Summary description

GRAPHITE HSS cylindrical drill bit for metal, 4.5 mm diameter (model 55H020). Made from high-speed steel (HSS) for cutting and drilling metal materials, suitable for workshop and industrial use. Designed for drilling holes in steel, iron and similar metals with standard drill chucks. Compact size for precision drilling and retrofit in handheld drills and drill presses.

## Long description

GRAPHITE HSS cylindrical drill bit for metal, 4.5 mm diameter, is a precision tool designed for drilling small to medium holes in steel, iron and comparable ferrous materials. Manufactured from high-speed steel (HSS), this 4.5 mm drill bit is suited to use in standard drill chucks of handheld drills and drill presses, offering consistent cutting performance and durability for workshop and industrial applications.
Advantages
The high-speed steel construction provides heat resistance and wear strength during sustained drilling in metal. Its cylindrical shank ensures stable clamping in standard chucks, enabling accurate hole placement and reduced runout. The 4.5 mm diameter delivers a balance between precision and material removal rate, suitable for pilot holes, fastening points and retrofit applications in mechanical assemblies.
Suitable for
Drilling holes in mild and medium carbon steels
Creating pilot holes for taps and fasteners
Workshop repairs and light industrial production
Use in handheld drills and bench drill presses
Key specifications
Material: high-speed steel (HSS)
Tip type: standard twist point for metal
Shank type: cylindrical shank for standard chucks
Diameter: 4.5 mm
Typical applications: cutting and drilling ferrous metals
How to use
Secure the drill bit in the chuck ensuring the cylindrical shank is clamped straight and tight. Select an appropriate rotational speed for the workpiece material — lower speeds for harder steels, higher speeds for softer metals. Use cutting fluid or lubricant to reduce heat buildup and improve tool life. Apply steady feed pressure without forcing the bit; withdraw periodically for chip removal when drilling deeper holes. After use, clean chips and lubricant residues and store the bit in a protected holder.
Usage recommendations
For optimal performance, match drill speed and lubrication to the steel grade being machined, and inspect the cutting edge for wear before precision tasks. Replace the bit when chipping or excessive wear appears to maintain hole quality and workpiece accuracy.
