Drill Bit Set MEGA HSS for Metal, cylindrical shank, sizes 2–8 mm (set, model 26213)

Set of MEGA HSS drill bits for metal with cylindrical shanks, covering metric sizes from 2 mm to 8 mm. The set is intended for drilling precise holes in steel and other ferrous and non‑ferrous metals. High speed steel (HSS) construction offers wear resistance and improved heat tolerance compared with ordinary carbon steel bits, making the set suitable for workshop, maintenance and construction tasks that require repeatable, accurate metal drilling.

Advantages

The HSS material provides a balance of hardness and toughness for sustained cutting performance and resistance to moderate overheating. Cylindrical shanks ensure compatibility with standard drill chucks and provide stable clamping during operation. The included size range from 2 mm to 8 mm covers common hole diameters used in metalworking, reducing the need to change tools frequently.

Suitable for

• Drilling holes in mild and alloy steels
• Drilling non‑ferrous metals such as aluminium and copper
• General workshop and maintenance tasks
• Construction and installation work requiring metal fastener holes

Key specifications

• Material: High speed steel (HSS)
• Shank type: Cylindrical
• Size range: 2 mm to 8 mm (metric sizes at regular increments)
• Intended use: Metal drilling (ferrous and non‑ferrous)

How to use

Select the appropriate drill bit size for the required hole diameter and clamp the cylindrical shank securely in a compatible drill chuck. Use moderate feed pressure and appropriate spindle speed for the material being drilled: lower speeds for harder steels, higher speeds for softer non‑ferrous metals. Apply cutting fluid when drilling steel or other metals to reduce heat and improve tool life. Clear chips periodically to avoid clogging and maintain cutting efficiency.

Usage recommendations

For best results, start with a centre punch to prevent bit walking, drill a pilot hole for large diameters, and use appropriate personal protective equipment. Store bits in a dry, organised case or rack to prevent damage and corrosion.
