Drill bit EPM HSS cylindrical for metal 8 mm (model E-500-1080)

Cylindrical HSS drill bit by EPM with an 8 mm cutting diameter, designed specifically for drilling metal. Manufactured from high-speed steel, this straight-shank bit is suitable for use with hand drills and drill presses that accept an 8 mm shank or compatible chucks. It is intended for producing precise, clean holes in steel, iron and other ferrous and non-ferrous metal workpieces encountered in workshop, repair and maintenance tasks.

Advantages

The HSS material provides good wear resistance and heat tolerance during medium-speed drilling in metal, helping to maintain cutting performance and hole accuracy. The cylindrical straight shank ensures secure clamping in standard chucks and simplifies tool changes. The 8 mm diameter offers a common size for mechanical fittings and through-holes, balancing rigidity and versatility for general metalworking applications.

Suitable for

• Drilling holes in steel and cast iron components
• Creating holes in sheet metal and metal plates
• Workshop, maintenance and repair operations
• Use with hand drills and drill presses with compatible chucks

Key specifications

• Cutting diameter: 8 mm
• Material: high-speed steel (HSS)
• Shank type: cylindrical / straight shank
• Intended application: metal drilling (ferrous and non-ferrous)
• Typical compatible tools: hand drills and drill presses

How to use

Secure the workpiece to prevent movement and select a suitable cutting speed for the metal being drilled. Insert the drill bit into the chuck and tighten firmly. Use a center punch for accurate starting location if necessary. Apply steady feed pressure and moderate speed to avoid overheating; use cutting fluid or lubricant when drilling tougher steels to extend tool life and improve chip evacuation. Withdraw the bit periodically to clear chips on deep holes.

Usage recommendations

For best results, match spindle speed and feed to the specific metal grade, keep the bit adequately cooled with cutting fluid when drilling hard or thick materials, and replace the bit when wear or chipping reduces hole quality.
