Drill Bit Abraboro HSS cylindrical 6 mm

Abraboro HSS cylindrical drill bit 6 mm is a general-purpose cutting tool made from high-speed steel (HSS) designed for drilling precise holes in a variety of materials. The 6 mm diameter and cylindrical shank ensure stable clamping in chucks and holders, making this drill bit suitable for workshop and production use. It is engineered to cut through steel, non-ferrous metals, plastics and wood, providing consistent hole quality for assembly, fabrication and maintenance tasks.

Advantages

The HSS material maintains hardness at elevated temperatures and offers good wear resistance for general metalworking and woodworking. The cylindrical shank provides reliable grip in standard chucks and collets, reducing runout and improving accuracy. Its 6 mm size is a common, versatile diameter for pilot holes and fastener clearance, allowing compatibility with a wide range of screws, bolts and dowels. The drill geometry is optimized for general-purpose performance across different materials.

Suitable for

• Drilling holes in mild and alloy steels
• Working with non-ferrous metals such as aluminium and brass
• Creating openings in plastics and composite materials
• Wood drilling for furniture making and joinery
• Workshop repair, assembly and production drilling tasks

Key specifications

• Material: High-speed steel (HSS)
• Shank type: Cylindrical shank for standard chucks and collets
• Diameter: 6 mm
• Intended use: Metalworking, woodworking and plastics
• Tip/geometry: General-purpose drill point suitable for through-holes and pilot holes

How to use

Select appropriate rotational speed and cutting fluid based on the workpiece material: moderate to high speeds for wood and plastics, and lower speeds with coolant for steel and harder alloys. Secure the workpiece and clamp the 6 mm cylindrical shank firmly in a compatible chuck or holder. Start drilling with steady, even feed pressure, withdraw occasionally to clear chips when drilling deep holes, and finish with a light backing pass if a clean exit is required.

Usage recommendations

For best results when drilling steel and other metals, use cutting oil and lower RPM to reduce heat and prolong bit life. For plastics and wood, use higher speeds with light pressure to avoid melting or tear-out. Replace the bit when tip wear or chipping affects hole quality, and inspect clamping surfaces to ensure concentricity and minimize runout.
