Drill bit EPM HSS cylindrical for metal 3.2 mm, set of 2 (E-500-1032)

Drill bit EPM HSS cylindrical for metal 3.2 mm, set of 2 is a precision ground high-speed steel (HSS) drill designed for metalworking tasks. The pair of cylindrical-shank bits is suitable for use in standard handheld drills and drill presses, offering consistent 3.2 mm hole diameters for fabrication, maintenance and workshop repair operations. The HSS material provides a balance of hardness and toughness for drilling steel and non-ferrous metals at typical workshop speeds.

Advantages

These HSS cylindrical drill bits deliver accurate hole sizes with good edge retention and dimensional stability during normal drilling conditions. The cylindrical shank ensures reliable clamping in standard chucks, and the HSS construction resists wear and heat build-up better than general carbon-steel bits when used within recommended speeds. Supplied as a set of two, they provide a spare bit for repeated tasks or a replacement in case of breakage.

Suitable for

• Drilling steel and non-ferrous metals (aluminium, brass, copper)
• Precision holemaking in sheet metal and thin-walled components
• Workshop maintenance, machine repairs and metal fabrication
• Use with handheld drills and drill presses

Key specifications

• Diameter: 3.2 mm
• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight) shank for standard chucks
• Package quantity: 2 pieces
• Intended application: metal drilling (ferrous and non-ferrous)

How to use

Secure the workpiece firmly in a vise or with clamps to prevent movement. Select a suitable drill speed for HSS bits and the material being drilled—lower speeds for harder steels, higher speeds for softer non-ferrous metals. Insert the 3.2 mm cylindrical shank into the drill chuck and tighten securely. Apply steady, moderate pressure and allow the bit to cut without excessive force. Withdraw periodically to clear chips and reduce heat build-up. Use cutting fluid or lubricant when drilling steel to extend bit life and improve hole quality.

Usage recommendations

For best results, match drill speed to material hardness, keep the bit cool with cutting fluid when drilling steel, and replace the bit when wear or chipping degrades hole quality. Avoid excessive side load to prevent breakage and ensure accurate, round holes.
