Drill Bit Abraboro HSS cylindrical 5.5 mm, single piece

Abraboro HSS cylindrical drill bit, 5.5 mm diameter, single piece: a high-speed steel cutting tool designed for general drilling in metal and wood. The 5.5 mm diameter provides a common pilot or clearance hole size for fastening and assembly tasks. The cylindrical shank fits standard chucks and hand drills, enabling straightforward mounting and stable rotation for accurate hole making. The tool is intended for applications where a durable HSS bit is required for clean, precise holes in a range of materials.

Advantages

The Abraboro HSS cylindrical drill bit combines high-speed steel hardness with a conventional flute geometry to deliver consistent cutting performance and wear resistance. Its cylindrical shank ensures compatibility with most drill chucks and minimizes slippage during use. Supplied as a single piece, the bit is suitable for one-off requirements or to complement a set, and its 5.5 mm diameter meets common sizing needs for pilot holes, clearance holes, and light fabrication work.

Suitable for

• Drilling holes in mild steel, non-ferrous metals and alloy sheets
• Woodworking tasks requiring a 5.5 mm pilot or clearance hole
• General maintenance, assembly and fastening operations
• Use with handheld drills and drill presses that accept cylindrical shanks

Key specifications

• Material: high-speed steel (HSS)
• Shank type: cylindrical
• Drill diameter: 5.5 mm
• Supply quantity: single piece
• Intended materials: metals and wood (general purpose)

How to use

Secure the cylindrical shank in the drill chuck and tighten firmly to prevent slippage. Select an appropriate spindle speed for the material being drilled—lower speeds for harder metals, higher speeds for wood and softer non-ferrous metals. Use cutting lubricant or coolant when drilling steels to reduce heat and extend tool life. Apply steady, moderate feed pressure and allow the bit to cut without forcing; withdraw periodically to clear chips when drilling deeper holes. After use, remove debris from flutes and store the bit in a dry place.

Usage recommendations

For best results when drilling steel, use cutting oil and moderate speed; for wood and aluminium, higher speeds without lubricant are appropriate. Match drill speed and feed to material hardness and thickness, and inspect the bit for wear before precise work.
