Drill bit EPM HSS cylindrical 5 mm for metal, model E-500-1050

EPM HSS cylindrical drill bit 5 mm is a general-purpose metalworking tool designed for creating clean, accurate holes in steel, iron and non-ferrous metals. Manufactured from high-speed steel (HSS), this 5 mm twist drill offers wear resistance and consistent cutting performance for workshop and industrial applications. The cylindrical shank fits standard chucks and drill presses, providing stable mounting and straightforward use in handheld drills and bench drilling machines.

Advantages

The high-speed steel construction ensures durability and heat resistance during sustained drilling in metal. The 5 mm diameter and twist geometry provide a balance between hole accuracy and material removal rate. The cylindrical shank allows secure clamping in a wide range of chucks and drill holders, enabling compatibility with common drilling equipment. The bit’s design minimizes chatter and helps maintain concentricity for repeatable results.

Suitable for

• Drilling pilot and through-holes in mild and alloy steels
• Creating holes in cast iron and non-ferrous metals such as aluminum and brass
• Workshop maintenance, fabrication and general machine shop tasks
• Use in drill presses, handheld electric drills and drilling rigs with standard chucks

Key specifications

• Material: high-speed steel (HSS)
• Cutting diameter: 5 mm
• Shank type: cylindrical
• Intended material: steel, iron, non-ferrous metals
• Tool type: twist drill bit for metalworking

How to use

Secure the drill bit in the chuck so that the shank is clamped tightly and runs true. Mark the drilling position and, where appropriate, use a center punch to prevent walk. Start drilling at low speed to establish the hole, then increase speed according to the metal type and drill size. Apply steady, moderate feed pressure and use cutting fluid or lubricant when drilling harder steels to reduce heat and extend tool life. Withdraw periodically to clear chips when drilling deep holes.

Usage recommendations

For best performance, select drill speeds appropriate to the workpiece material (lower RPM for harder steels, higher RPM for softer non-ferrous metals) and use suitable cutting fluid. Inspect and replace the bit if excessive wear or chipping appears. Store in a dry place to prevent corrosion of the HSS surface.
