Drill bit set MILWAUKEE HSS-G TiN for metal, 19-piece, hex shank

Drill bit set MILWAUKEE HSS-G TiN for metal, 19-piece, hex shank is a collection of high-speed steel twist bits with a titanium nitride (TiN) coating, developed for drilling through various metals. The set covers a range of common metric diameters and uses a hex shank to secure the bit in hex chucks and quick-change holders, providing stable engagement during drilling operations in workshops and maintenance environments.

Advantages

The HSS-G base material offers good toughness for general-purpose metal drilling while the TiN coating increases surface hardness and reduces friction, extending tool life compared with uncoated bits. The hex shank enables fast, secure bit changes and reduces slippage in compatible chucks. The set format keeps multiple sizes organized for varied tasks and reduces downtime spent swapping individual bits.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminium and other non-ferrous metals
• Workshop drilling and maintenance tasks
• Professional metalworking and fabrication where multiple sizes are required
• Use with cordless and corded drills equipped with hex chucks or quick-change adapters

Key specifications

• Material: high-speed steel (HSS-G) with titanium nitride (TiN) coating
• Number of pieces: 19
• Shank type: hex shank for secure fit in hex chucks and quick-change holders
• Bit type: twist drill geometry suitable for metal
• Packaging: compact set for organized storage and transport

How to use

Select the appropriate drill diameter for the required hole and mount the bit securely in a compatible hex chuck or quick-change holder. Use appropriate cutting speed and feed for the metal being drilled, apply cutting fluid when machining harder steels to reduce heat and wear, and support the workpiece to prevent movement. Maintain steady pressure without forcing the bit; retract occasionally to clear swarf and allow cooling.

Usage recommendations

Use cutting oil for stainless steel and harder alloys, start with a pilot hole for large diameters, and ensure proper clamping of thin sheets to prevent vibration. Replace worn bits to maintain hole quality and reduce the risk of breakage.
