Drill bit for metal Smart HSS 15.0 mm × 114/169 mm – single piece

Drill bit for metal Smart HSS 15.0 mm × 114/169 mm – single piece is a high-speed steel (HSS) cutting tool designed for drilling ferrous metals. With a 15.0 mm diameter, usable length 114 mm and overall length 169 mm, this single-piece HSS bit is intended for through and spot drilling in steel and similar materials. The solid construction and standard geometry provide consistent hole quality in workshop and maintenance settings.

Advantages

The HSS material offers good hardness and heat resistance for metalworking tasks, maintaining sharpness under typical drilling speeds. Its 15.0 mm diameter and extended usable length allow for deeper holes while preserving rigidity. As a single-piece supply, the bit is convenient for ad-hoc repairs, maintenance, and small-batch fabrication where individual replacement tools are needed. The overall design supports compatibility with common drill chucks and bench drills used in professional and hobbyist environments.

Suitable for

• Drilling steel and other ferrous metals
• Through-hole and spot drilling operations
• Workshop repairs and maintenance tasks
• Precision metal fabrication in small batches
• Use with hand drills, drill presses and bench drills

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 15.0 mm
• Usable (working) length: 114 mm
• Overall length: 169 mm
• Shank type: straight cylindrical shank suitable for standard chucks
• Intended materials: steel and other ferrous metals

How to use

Secure the drill bit firmly in a compatible chuck and set the drill to an appropriate speed for HSS bits and the thickness of the workpiece. Use cutting fluid or coolant when drilling steel to reduce heat buildup and prolong tool life. Start with a centre punch for accurate hole placement if needed, then drill with steady pressure, withdrawing occasionally to clear chips and allow cooling. After use, clean the bit of swarf and store it in a dry place to prevent corrosion.

Usage recommendations

For best results when drilling steel, select a lower spindle speed for larger diameters, apply cutting fluid, and avoid excessive force that can cause bit breakage or accelerated wear.
