Drill bit set Abraboro HSS cylindrical for metal 6.3 mm, 10 pcs (AB00010630)

Abraboro HSS cylindrical drill bit set for metal, 6.3 mm diameter, 10 pieces is a ready-to-use assortment of high-speed steel twist drills designed for cutting holes in steel and other metal materials. Each bit has a cylindrical shank suitable for standard chucks on handheld drills and drill presses. The set is intended for general metalworking, maintenance and repair tasks where precise 6.3 mm holes are required and offers consistent geometry and hardness for reliable drilling performance.

Advantages

High-speed steel construction ensures a good balance of hardness and toughness for drilling into mild and medium-hard steels. Cylindrical shanks provide compatibility with most drill chucks and allow straightforward swapping of bits during projects. The consistent 6.3 mm diameter across all ten pieces simplifies selection for repetitive tasks and reduces downtime. Designed for general-purpose metal drilling, the set provides a cost-effective way to maintain a supply of identical replacement bits for production or workshop use.

Suitable for

• Drilling holes in mild steel, sheet metal and non-ferrous metal parts
• Maintenance and repair tasks requiring 6.3 mm holes
• Use with handheld electric drills and bench drill presses
• Workshop stock for general metalworking and fabrication

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical (straight) shank
• Drill diameter: 6.3 mm
• Quantity: 10 pieces
• Intended application: metal drilling (steel, sheet metal, non-ferrous metals)

How to use

Select a suitable drill chuck and secure the cylindrical shank firmly. Mark the drilling location and, if necessary, use a center punch to prevent bit walking. Start at low speed to establish a pilot engagement, then increase speed appropriate to the material being drilled. Apply steady, moderate feed pressure and use cutting fluid when drilling steel to extend bit life and improve chip evacuation. Withdraw the bit periodically to clear chips and avoid overheating.

Usage recommendations

For best results when drilling steel, use light cutting oil and moderate speeds to reduce wear and prevent work hardening. Secure workpieces properly, and replace worn or chipped bits to maintain hole quality and operator safety.
