Drill bit for metal EPM HSS cylindrical 12 mm model E-500-1120

Drill bit for metal EPM HSS cylindrical 12 mm model E-500-1120 is a 12 mm diameter high-speed steel (HSS) twist drill designed for drilling metal workpieces. The cylindrical shank fits standard chucks on handheld drills and drill presses, allowing straightforward mounting and stable rotation. The HSS material provides hardness and heat resistance needed for cutting through a wide range of ferrous and non-ferrous metals while maintaining cutting edge durability for repeated use in workshop, construction, and maintenance tasks.

Advantages

The HSS construction ensures good wear resistance and sustained cutting performance at elevated temperatures typical of metal drilling. The cylindrical shank offers compatibility with common drill chucks and provides secure clamping for straight holes. The 12 mm diameter is suitable for medium-sized holes often required in fabrication, repair, and installation operations. The geometry of the flutes promotes efficient chip evacuation and contributes to consistent hole quality.

Suitable for

• Drilling holes in steel, stainless steel, aluminum and other metal alloys
• Use with handheld electric drills and bench drill presses
• Workshop, maintenance and construction drilling tasks
• General fabrication and metalworking operations requiring precise 12 mm holes

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical
• Diameter: 12 mm
• Intended use: Metal drilling
• Compatible tools: Handheld drills and drill presses

How to use

Select the appropriate drill speed and coolant or cutting fluid based on the metal being drilled. Secure the workpiece firmly in a vice or with clamps to prevent movement. Mount the cylindrical shank in the drill chuck and tighten securely. Start drilling at low speed to establish a center and then increase speed as appropriate for the material, applying steady pressure without forcing. Withdraw the bit periodically to clear chips and reduce heat buildup for longer tool life.

Usage recommendations

For best results, use cutting fluid when drilling harder metals and moderate drill speeds for stainless steel. For aluminum and softer non-ferrous alloys, slightly higher speeds and light lubrication improve chip evacuation. Inspect the tip for wear and regrind or replace the bit when hole quality or cutting performance declines.
