Drill bit set MILWAUKEE HSS-G TiN for metal, 10.5 mm, 5 pieces

The MILWAUKEE HSS-G TiN drill bit set for metal contains five 10.5 mm diameter bits designed for cutting holes in a variety of metal materials. Each drill bit is made from high-speed steel (HSS-G) and finished with a titanium nitride (TiN) coating to improve surface hardness, reduce friction and extend service life under demanding workshop and construction conditions.

Advantages

The combination of high-speed steel and TiN coating delivers improved wear resistance and longer bit life compared with uncoated HSS variants. Precision ground flutes and a standardized 118° point angle support accurate centering and consistent chip evacuation. The 10.5 mm diameter is suitable for preparing medium-size holes where strength and hole quality are required.

Suitable for

• Drilling through mild and medium carbon steel
• Workshop and maintenance tasks requiring repeatable metal holes
• Construction and installation work on metal components and fixtures
• Use with corded or cordless drills and drill presses for metalworking

When it may not be suitable

This drill bit set is intended for drilling metal and is not optimized for masonry, tile, glass or wood where specific geometries and materials are preferable. For very hard alloys, stainless steel grades with high hardness, or production applications requiring extreme tool life, carbide or specialized cobalt drills may be more appropriate.

Key specifications

• Material: high-speed steel (HSS-G)
• Coating: titanium nitride (TiN)
• Diameter: 10.5 mm
• Quantity: 5 pieces
• Point angle: 118° (standard geometry)

How to use

Secure the appropriate drill bit in the chuck of a drill or drill press with suitable clamping torque. Use cutting fluid or lubricant when drilling steel to reduce heat build-up and prolong tool life. Start at low speed to establish the hole, then increase speed as appropriate for material and drill capacity. Apply steady, moderate feed pressure and periodically clear chips from the hole to maintain cutting efficiency.

What to consider before purchase

• Verify the 10.5 mm diameter matches the required hole size for your application
• Consider the base material — HSS-G TiN is intended for general metalwork but may not be optimal for very hard alloys
• Confirm compatibility with your drill chuck and required shank type and clamping range

Usage recommendations

For best results when drilling steel, use appropriate cutting fluid, maintain moderate speeds, and allow the bit to cool between extended runs. Replace bits that show excessive wear or chipping to preserve hole quality and reduce load on the drill.
