Drill bit for metal EPM HSS cylindrical 8.5 mm model E-500-1085
Drill bit for metal EPM HSS cylindrical 8.5 mm model E-500-1085
Cylindrical HSS drill bit by EPM, nominal diameter 8.5 mm, designed specifically for drilling metal. Manufactured from high-speed steel (HSS) to provide cutting performance and wear resistance in common metalworking operations. The bit has a straight shank intended for use in drill chucks of hand drills and drill presses and is suitable for creating through and blind holes in steel as well as in many ferrous and non-ferrous metals where an 8.5 mm diameter hole is required.
The EPM HSS 8.5 mm drill bit offers consistent diameter tolerance and edge retention typical of high-speed steel tooling, which supports repeatable hole quality. Its cylindrical (straight) shank simplifies mounting in standard chucks and reduces slippage under normal operating conditions. The material choice gives a balance of hardness and toughness to resist wear and chipping during general metal drilling tasks. This tool is compatible with standard drilling speeds and common cutting fluids to extend life and improve chip evacuation.
Secure the drill bit firmly in the chuck of a hand drill or drill press so the shank is fully clamped. Select an appropriate spindle speed for HSS drilling — moderate to high speeds for non-ferrous metals and lower speeds for harder steels — and apply steady feed pressure. Use cutting fluid or coolant when drilling steel to reduce heat, improve chip removal and prolong tool life. Clear chips from the hole periodically to avoid packing and overheating. After use, remove deposits and store the bit in a dry location to prevent corrosion.
For best results, pre-drill with a suitable pilot hole when accurate positioning is required, and adjust speed and feed according to the workpiece material. Replace the bit if excessive wear or chipping appears to maintain hole quality and safety.
