Drill bit EPM HSS cylindrical for metal 9 mm (E-500-1090)

Cylindrical HSS drill bit for metal, diameter 9 mm, designed by EPM for use in hand drills and drill presses. Made from high-speed steel (HSS), this 9 mm drill bit is intended for drilling accurate holes in steel, iron and a range of ferrous and non-ferrous metals. The solid cylindrical shank provides stable clamping in standard chucks and enables reliable performance in workshop, maintenance and production environments.

Advantages

The HSS material offers good hardness and heat resistance for drilling metal at moderate speeds. The cylindrical shank ensures straightforward mounting in a wide variety of hand-held and stationary drilling tools. The 9 mm diameter provides a common hole size for fittings and fasteners while maintaining dimensional accuracy. Overall design focuses on durability and repeatable hole quality when used under recommended cutting conditions.

Suitable for

• Drilling holes in steel and iron
• Working with aluminium and other non-ferrous metals
• Workshop repairs and maintenance
• Preparation for tapping or fastening

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 9 mm
• Shank type: cylindrical shank suitable for standard chucks
• Intended use: metal drilling
• Compatible tools: hand drills and drill presses

How to use

Select the 9 mm HSS drill bit and secure it in the drill chuck, ensuring the shank is fully inserted and clamped. Mark the drilling point and, if needed, use a center punch to prevent wandering. Set the drill to an appropriate speed for metal and apply steady pressure while keeping the bit perpendicular to the workpiece. Use cutting fluid or coolant as required to reduce heat and extend tool life. Withdraw the bit periodically to clear chips when drilling deeper holes.

Usage recommendations

Use medium to low spindle speeds for harder steels and higher speeds for softer metals; apply cutting fluid to improve tool life and hole finish. Inspect the bit for wear or damage before use and replace when cutting performance declines to avoid poor hole quality or workpiece damage.
