Drill Bit EPM HSS cylindrical 11 mm, model E-500-1110

Cylindrical HSS drill bit by EPM with an 11 mm cutting diameter, model E-500-1110, is designed for drilling metal in workshop and maintenance environments. Made from high-speed steel (HSS), the bit combines hardness and wear resistance to perform repeated drilling operations in a range of ferrous and non-ferrous materials. The straight cylindrical shank is suitable for use in handheld drills and drill presses, providing straightforward mounting and stable rotation.

Advantages

The HSS construction offers good heat resistance and prolonged cutting life compared with standard carbon steel bits. The 11 mm diameter provides a balance between rigidity and material removal rate for common metalworking tasks. A cylindrical shank ensures compatibility with common drill chucks and simple clamping, while the ground flute geometry promotes chip evacuation and consistent hole quality.

Suitable for

• Drilling holes in steel and iron
• Working with non-ferrous metals such as aluminum and brass
• Workshop maintenance and repair tasks
• Use with handheld drills and drill presses

Key specifications

• Cutting diameter: 11 mm
• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight) shank suitable for standard chucks
• Intended material: ferrous and non-ferrous metals
• Typical applications: metalworking, maintenance, fabrication

How to use

Select an appropriate drilling speed for the 11 mm HSS bit and the material being machined; lower speeds are generally recommended for harder steels and higher speeds for softer non-ferrous metals. Secure the workpiece firmly, align the drill perpendicular to the surface, and use steady feed pressure. Apply cutting fluid or lubricant when drilling tougher steels to reduce heat and improve tool life. After drilling, clear chips from the flutes before retracting the bit completely.

Usage recommendations

For best results, clamp the workpiece and use a drill press when high precision is required. Use cutting fluid for steel and periodically inspect the bit for wear or chipping; replace when dull to maintain hole quality and reduce risk of workpiece damage.
