Drill Bit EPM HSS cylindrical 7.5 mm model E-500-1075 for metal

Cylindrical HSS drill bit by EPM with a 7.5 mm cutting diameter, model E-500-1075, is designed for drilling metal. Made from high-speed steel (HSS) to provide wear resistance and thermal stability, this drill bit is intended for general metalworking tasks where precise, clean holes are required. Its cylindrical shank fits standard chucks in manual and machine drills and is suitable for work on steel, cast iron and non-ferrous metals.

Advantages

The high-speed steel construction offers consistent hardness at elevated temperatures, improving tool life during continuous drilling. The 7.5 mm diameter provides a balance between rigidity and cutting speed for medium-sized holes. A cylindrical shank ensures secure clamping in a wide range of drill chucks, and the geometry is optimized for accurate centring and chip evacuation when used with appropriate cutting speeds and lubrication.

Suitable for

• Drilling through mild and alloy steels
• Creating holes in cast iron and non-ferrous metals (aluminium, brass)
• Use in handheld electric drills and drill presses
• General metal fabrication, maintenance and repair tasks

Key specifications

• Material: High-speed steel (HSS)
• Cutting diameter: 7.5 mm
• Shank type: Cylindrical shank for standard chucks
• Intended application: Drilling metal

How to use

Mark and center-punch the drilling point to improve accuracy. Secure the workpiece to prevent movement and fit the drill bit into the chuck, tightening firmly. Select the appropriate spindle speed for the metal being drilled — lower speeds for harder steels, higher speeds for softer non-ferrous metals. Use steady, even feed pressure and withdraw occasionally to clear chips. Apply cutting fluid or lubricant as required to reduce friction and heat, extending the bit's service life.

Usage recommendations

For best results, pre-drill pilot holes for larger diameters, maintain correct rotational speed and use suitable cutting fluid. Inspect the drill bit for wear before use and replace if the edge is dull or chipped to maintain drilling accuracy and safety.
