Drill bit Abraboro HSS tapered 17.0 mm AB44517000 for metal

Tapered HSS drill bit Abraboro 17.0 mm is designed for precise drilling and enlarging holes in metal. Made from high-speed steel, this conical drill bit offers progressive cutting and reliable centering, making it suitable for a variety of metalworking applications. The tool is intended for use with compatible drill chucks and standard drilling machines in fabrication, maintenance and repair environments.

Advantages

The tapered geometry ensures gradual engagement with the workpiece, reducing walking and improving centring without the need for a pilot hole. High-speed steel construction provides wear resistance and maintains cutting performance at typical drilling speeds for ferrous materials. The single-tool design simplifies hole enlargement and step drilling operations while offering consistent hole quality and straightforward compatibility with common drill chucks.

Suitable for

• Drilling and enlarging holes in steel and other ferrous metals
• Workshop fabrication and metal maintenance tasks
• Step drilling where progressive hole sizes are required
• Use with handheld or bench-top drilling machines equipped with compatible chucks

Key specifications

• Material: high-speed steel (HSS)
• Shank type: tapered conical geometry for progressive cutting and centring
• Cutting diameter: 17.0 mm
• Intended use: drilling and enlarging holes in ferrous metals
• Compatibility: designed for standard drill chucks and machines that accept tapered bits

How to use

Secure the tapered drill bit in a compatible drill chuck or tapered arbor according to the machine manufacturer's instructions. Mark the drilling position on the workpiece and clamp it firmly. Start drilling at low-to-moderate speed to establish a centred entry, then increase speed as appropriate for the material and bit size. Apply steady feed pressure and use cutting fluid when working with steel to reduce heat, improve chip evacuation and extend tool life. Withdraw periodically to clear chips on deep holes.

Usage recommendations

Use appropriate personal protective equipment and follow machine safety guidelines. For best results on hardened or heat-treated steels, check material hardness and consider a specialized drill or lower cutting speed. Regularly inspect the flute and cutting edges for wear and regrind or replace the bit when cutting performance decreases.
