Drill bit for metal EPM HSS cylindrical 3 mm (2 pcs) E-500-1030

Drill bit for metal EPM HSS cylindrical 3 mm (2 pcs) E-500-1030 are high-speed steel twist drill bits with a 3 mm cutting diameter, supplied as a pack of two. Designed for drilling a variety of ferrous and non-ferrous metals, these cylindrical-shank bits offer a balance of hardness and toughness appropriate for general-purpose metalworking, maintenance and repair tasks requiring small, accurate holes.

Advantages

The HSS material retains hardness at elevated cutting temperatures, providing extended life under typical metal-drilling speeds. The cylindrical shank ensures compatibility with standard drill chucks and simple mounting, while the 3 mm diameter enables precise, small-diameter hole making. Supplied in a two-piece set, the pack gives an immediate spare for uninterrupted work.

Suitable for

• Drilling holes in mild steel, aluminum and other common metals
• General metalworking and fabrication tasks
• Maintenance, repair and assembly requiring precise small holes
• Preparing pilot holes for tapping small threads

Key specifications

• Material: high-speed steel (HSS)
• Cutting diameter: 3 mm
• Shank type: cylindrical
• Pack quantity: 2 pieces
• Intended application: metal drilling

How to use

Select the correct drilling speed and feed for the metal you are working with and secure the workpiece to prevent movement. Install the cylindrical HSS bit in a suitable chuck, ensuring it is centered and tightened. Use cutting fluid or coolant when drilling harder metals to reduce heat and extend tool life. Apply steady, moderate pressure and withdraw periodically to clear chips and avoid clogging the flutes.

Usage recommendations

For best results, start with a low to moderate speed for harder steels and increase speed for softer metals such as aluminum; use appropriate lubricants when drilling stainless steel or other tough alloys. Replace bits when wear becomes visible or accuracy declines to maintain hole quality.
