Drill Bit EPM HSS-G Silver 15.5 mm

EPM HSS-G Silver 15.5 mm is a high-speed steel twist drill designed for metalworking and general-purpose drilling. The 15.5 mm diameter and HSS-G construction provide rigidity and wear resistance for drilling into steels and other common metals. This drill bit is intended for use in handheld drills and drill presses in workshops, maintenance tasks, and fabrication environments.

Advantages

The HSS-G material ensures a balance of hardness and toughness suitable for drilling metal; the silver finish improves chip flow and reduces friction during cutting. Its 15.5 mm diameter offers a precise hole size for fitting fasteners or preparing parts, while the twist-drill geometry supports efficient cutting and chip evacuation. The bit is compatible with standard drill chucks used in portable and stationary drilling equipment.

Suitable for

• Drilling holes in steel and non-hardened metal components
• Workshop and maintenance drilling with handheld drills
• Drill press operations for general fabrication tasks
• Preparing holes for bolts, rivets, or clearance fits

Key specifications

• Material: High-speed steel (HSS-G)
• Diameter: 15.5 mm
• Type: Twist drill
• Finish: Silver
• Intended use: Metalworking and general drilling tasks

How to use

Secure the drill bit in a compatible chuck and set the drill or drill press to an appropriate speed for high-speed steel when cutting metal. Use steady feed pressure and maintain correct alignment to the workpiece to achieve a clean hole. Apply cutting fluid or lubricant as required for improved life and chip evacuation when drilling tougher materials. After use, clean chips from the flutes and store the bit dry to prevent corrosion.

Usage recommendations

For best results when drilling steel, select drill speeds and cutting fluids suitable for HSS-G bits, avoid excessive feed rates that may cause breakage, and check chuck tightness before operation. Use appropriate personal protective equipment and clamp workpieces securely.
