Drill bit Abraboro HSS cylindrical 15.5 mm for metal, model AB00011551

Abraboro HSS cylindrical 15.5 mm drill bit for metal is a single-flute cutting tool made from high-speed steel designed for general metalworking. The straight cylindrical shank fits standard chucks of handheld drills and drill presses, delivering reliable hole drilling in steel and a wide range of ferrous and non-ferrous metals. This bit is intended for workshop and maintenance use where a robust HSS cutting edge and standard shank compatibility are required.

Advantages

The high-speed steel construction provides wear resistance and sustained cutting performance at typical drilling speeds for metal. The cylindrical shank ensures secure clamping in chucks without the need for adaptors, while the 15.5 mm cutting diameter enables medium-sized holemaking for assembly, repair, and fabrication tasks. The geometry is optimized for general-purpose metal drilling, balancing penetration rate and chip evacuation for common steels and softer non-ferrous alloys.

Suitable for

• Drilling holes in carbon steel and alloy steel components
• Creating openings in aluminium, copper and other non-ferrous metals
• Routine workshop maintenance and repair tasks
• Use with handheld electric drills and bench drill presses

Key specifications

• Cutting material: High-speed steel (HSS)
• Cutting diameter: 15.5 mm
• Shank type: Cylindrical (straight) shank for standard chucks
• Intended material: Ferrous and non-ferrous metals
• Typical applications: General metal drilling, maintenance, fabrication

How to use

Secure the drill bit in the chuck of a handheld drill or drill press ensuring the shank is fully inserted and tightened. Select an appropriate drilling speed and feed rate for the metal being worked—lower speeds for hardened steels and higher speeds for softer non-ferrous metals. Use cutting fluid or coolant to reduce heat and prolong tool life when drilling tougher steels. Apply steady, moderate pressure and allow the bit to cut without excessive lateral force; periodically withdraw the bit to clear chips when drilling deeper holes.

Usage recommendations

For best results, match drilling speed and lubrication to the workpiece: slower speeds and cutting fluid for hardened steels, moderate speeds for general steel, and higher speeds for aluminium and copper. Inspect the bit for wear before use and replace when the cutting edge becomes dull to avoid workpiece damage and excessive heat buildup.
