Drill bit for metal Smart HSS cylindrical 5 mm, pack of 10 (model 24-050)

Smart HSS cylindrical drill bits, diameter 5 mm, pack of 10 (model 24-050) are designed for drilling precise through holes and routine metalworking tasks. Manufactured from high-speed steel, these straight-shank bits are suitable for use in portable drills and drill presses. The set of ten identical 5 mm bits provides consistent cutting performance for workshop, maintenance and production environments where reliable, repeatable holes in ferrous and non-ferrous metals are required.

Advantages

High-speed steel construction provides wear resistance and heat tolerance during continuous drilling. The cylindrical (straight) shank ensures stable clamping in standard drill chucks and compatibility with a wide range of drilling equipment. A 5 mm cutting diameter delivers accurate hole size for fasteners, dowels and assembly work. Supplied as a pack of ten, the set reduces downtime by providing spare bits for repeated operations and maintenance tasks.

Suitable for

• Drilling through holes in steel, stainless steel, aluminum and other metals
• Workshop repairs and routine maintenance of machinery and equipment
• Use with portable electric drills and bench drill presses
• Production runs and small-batch metal fabrication

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical / straight shank
• Cutting diameter: 5 mm
• Pack quantity: 10 pieces
• Intended materials: Ferrous and non-ferrous metals

How to use

Secure the appropriate 5 mm HSS bit in the drill chuck and tighten firmly. Select drill speed according to the metal type—lower speeds for harder steels, higher speeds for aluminum. Use cutting fluid or lubricant when drilling ferrous metals to reduce heat and extend bit life. Apply steady feed pressure and avoid excessive side load to maintain hole accuracy and prevent premature wear.

Usage recommendations

For best results, clamp the workpiece securely and mark the hole centre before drilling. Start with a small pilot mark or center punch for precise positioning. Replace bits that show significant wear, chipping or loss of cutting edge to preserve hole quality and operator safety.
