Drill bit Abraboro HSS-R 5.8 mm x 93 mm cutting length 57 mm — pack of 10

Solid HSS-R metal drill bit Abraboro with a 5.8 mm diameter, total length 93 mm and 57 mm cutting length. Designed for drilling steel and other ferrous materials, this twist drill is suitable for handheld drills and drill presses. Supplied as a pack of 10 identical bits, it is intended for workshop use, repairs and light production tasks that require consistent hole diameter and repeatability.

Advantages

The Abraboro HSS-R drill bit is made from high-speed steel with a conventional ground point geometry that provides balanced wear resistance and toughness when cutting ferrous metals. Its 57 mm cutting length allows drilling through medium-thickness steel plates and structural components while the 93 mm total length offers sufficient reach for recessed or deeper mounting situations. Supplied in a pack of 10, the bits enable quick replacement and consistent performance across repeated operations.

Suitable for

• Drilling mild and hardened steels in maintenance and repair work
• Workshop production where multiple identical holes are required
• Handheld electric drills and bench drill presses
• General metal fabrication and assembly tasks

Key specifications

• Material: high-speed steel (HSS-R)
• Diameter: 5.8 mm
• Total length: 93 mm
• Cutting/work length: 57 mm
• Geometry: conventional twist drill point for ferrous metals
• Pack quantity: 10 identical drill bits

How to use

Mark the drilling position and clamp the workpiece securely to prevent movement. Select an appropriate drill speed and feed for the material being drilled—lower speeds for harder ferrous metals and higher speeds for softer materials. Use cutting fluid or coolant when drilling steel to reduce heat, extend tool life and improve chip evacuation. Start drilling at low speed to establish the pilot and then proceed with steady pressure until the required depth is reached. Withdraw the bit periodically to clear chips if drilling deep holes.

Usage recommendations

For best results when drilling steel, use light cutting oil and moderate speeds to avoid premature wear. Ensure the drill is held perpendicular to the surface and replace bits from the pack when signs of dulling or chipping appear to maintain consistent hole quality.
