Drill bit Abraboro HSS cylindrical 7.5 mm for metal and wood

Abraboro HSS cylindrical drill bit 7.5 mm is designed for general-purpose drilling in metal and wood. Manufactured from high-speed steel (HSS), the bit offers reliable cutting performance and increased wear resistance for routine workshop, construction and maintenance operations. The cylindrical shank fits standard chucks, providing secure clamping and compatibility with a wide range of drills and drill presses. This 7.5 mm diameter tool creates precise round holes where consistent size and edge quality are required.

Advantages

The high-speed steel construction ensures good hardness and thermal resistance during typical drilling tasks, reducing premature wear. The cylindrical shank enables straightforward mounting in standard drill chucks and allows use with hand drills, bench drills and portable drilling machines. The geometry of the cutting edges is optimized for clean holes in both metal and wood, balancing chip removal and hole finish. The tool is suitable for repeated use in varied jobsite conditions and routine maintenance work.

Suitable for

• Drilling holes in mild steel, sheet metal and non-ferrous metals
• Creating precise openings in soft and hardwoods
• Workshop, fabrication and maintenance tasks
• Use with hand drills, drill presses and portable drilling machines
• General repair, installation and assembly work

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 7.5 mm
• Shank type: cylindrical (round) shank for standard chucks
• Intended materials: metal and wood
• Typical applications: general drilling, maintenance, workshop use

How to use

Select an appropriate drill speed and clamp the bit securely in the drill chuck. Mark the drilling point and, if needed, use a center punch for greater accuracy on metal. Apply steady, even pressure and allow the bit to cut without excessive force; withdraw periodically to clear chips when drilling deep holes. Use cutting fluid or lubricant when drilling metal to reduce heat and extend tool life. For wood, ensure proper feed rate to avoid splintering at the exit side.

Usage recommendations

Use lower speeds and cutting fluid for ferrous metals, and higher speeds for softer non-ferrous metals and wood. Inspect the cutting edges before use and replace the bit if worn or chipped to maintain hole quality and safe operation.
