## Long description

Two-piece set of GRAPHITE HSS drill bits with a 4.5 mm diameter manufactured to DIN 338 standard for metalworking. These high-speed steel bits are designed for drilling steel and a wide range of other metals, providing precise, clean holes for repair, fabrication and maintenance tasks. The set is suitable for use in handheld drills and drill presses where accuracy and consistent cutting performance are required.
Advantages
The GRAPHITE HSS bits maintain sharp cutting edges and resist wear during repetitive metal drilling. Compliance with DIN 338 ensures dimensional accuracy and reliable tip geometry for stable centring and reduced walking at the start of a hole. The 4.5 mm size addresses common small-to-medium hole requirements while the two-piece pack supplies a spare for continuous work or paired operations. These bits are appropriate for both professional and DIY metalworking where consistent hole quality and tool life are important.
Suitable for
Drilling holes in mild and hardened steel
Metal fabrication and assembly tasks
Maintenance, repair and overhaul operations
Use with hand drills and drill presses
Key specifications
Material: High-speed steel (HSS)
Standard: DIN 338 tip geometry and dimensions
Diameter: 4.5 mm
Pack quantity: 2 pieces
Intended application: Metal drilling
How to use
Secure the workpiece and select appropriate clamping to prevent movement. Mount the 4.5 mm HSS drill bit in a compatible chuck and tighten firmly. Start drilling at low speed to establish the centre, then increase speed to the recommended range for the specific metal being drilled. Apply steady, moderate feed pressure and use cutting fluid or lubricant when drilling steels to extend bit life and improve cut quality. Withdraw the bit periodically to clear chips and avoid overheating.
Usage recommendations
For best results when drilling steel, use recommended cutting oils, maintain correct drill speeds, and replace or resharpen bits showing wear. Match drill speed to material thickness and hardness; lower speeds for harder alloys. Store bits in a dry place to prevent corrosion and keep the spare bit available for continuous tasks.
