Drill bit EPM E-500-1021 HSS cylindrical 2.1 mm, set of 2

High-speed steel (HSS) cylindrical drill bits EPM E-500-1021 are provided as a set of two identical bits with a 2.1 mm cutting diameter. Designed for general-purpose drilling in metals, plastics and wood, these bits feature a straight cylindrical shank for secure clamping in chucks and are suitable for both manual handheld and machine drilling applications where precise small-diameter holes are required.

Advantages

The HSS material ensures a good balance of hardness and toughness for cutting common metals and non-ferrous materials while maintaining wear resistance during repeated use. The cylindrical shank allows straightforward mounting in standard drill chucks without additional adapters. Supplied as a pair, the set provides a spare bit for continuous work or for separate tools, reducing downtime. The small 2.1 mm diameter enables accurate pilot holes and detail work where compact, precise holes are needed.

Suitable for

• Drilling small-diameter holes in steel, aluminium and other non-hardened metals
• Creating pilot holes for screws and fasteners in wood and composite panels
• Detail and hobby work in plastics, model making and electronics enclosures
• Use in handheld drills, drill presses and milling machines with appropriate speed control

Key specifications

• Cutting diameter: 2.1 mm
• Material: High-speed steel (HSS)
• Shank type: Cylindrical (straight) shank compatible with standard chucks
• Pack quantity: Set of 2 identical drill bits
• Intended materials: Metals, plastics, wood

How to use

Select appropriate cutting speed and feed for the work material; lower speeds are recommended for harder metals while higher speeds suit plastics and wood. Secure the workpiece and clamp the cylindrical shank firmly in the drill chuck to minimize runout. Use cutting fluid or lubrication when drilling steels to extend tool life and improve chip removal. For precise small holes, start with a center punch or pilot mark to prevent bit wandering and proceed with steady pressure, withdrawing occasionally to clear chips.

Usage recommendations

For prolonged tool life, avoid excessive feed rates and overheating; apply light lubricant on steel and increase RPM for plastics. Replace the bit when wear or chipping reduces hole quality. Store the set in a dry place to prevent corrosion and keep one spare bit available for critical tasks.
