Drill bit EPM HSS cylindrical for metal 5.1 mm E-500-1051

EPM HSS cylindrical drill bit for metal, diameter 5.1 mm (model E-500-1051) is a high-speed steel cutting tool designed for drilling precise holes in ferrous and non-ferrous metals. The cylindrical shank fits standard chucks on hand drills and drill presses. The 5.1 mm diameter is suitable for metalworking tasks that require accurate clearance or pilot holes. Use appropriate drilling speeds and cutting fluid to maintain tool life and hole quality.

Advantages

The HSS material offers good hardness and heat resistance for sustained cutting performance when drilling metal. The cylindrical shank provides reliable clamping in chucks and allows quick tool changes. The geometry and sharp cutting edges are optimized for clean entry and reduced burr formation in thin sheet metal and structural components. This drill bit is compact and versatile for both portable and stationary drilling applications.

Suitable for

• Drilling holes in sheet metal and thin plates
• Creating clearance or pilot holes in pipes and tubing
• Workshop use on hand drills and drill presses
• Maintenance and repair tasks on mechanical assemblies

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 5.1 mm
• Shank type: Cylindrical
• Intended use: Ferrous and non-ferrous metals

How to use

Secure the drill bit in the drill chuck ensuring the shank is fully seated and tightened. Select an appropriate spindle speed for metal drilling—lower speeds for harder materials and higher speeds for soft metals—referencing standard drilling speed charts as needed. Apply cutting fluid or oil to the drilling area to reduce heat and improve chip evacuation. Start drilling with steady, moderate feed pressure and clear chips periodically. After drilling, remove burrs if necessary and clean the bit before storage.

Usage recommendations

Use coolant or cutting oil when drilling stainless steel or other hard alloys, and reduce speed to prevent premature wear. For thin sheets, support the material to avoid deformation and use backing when a clean exit hole is required. Inspect the bit for wear and resharpen or replace when cutting performance declines.
