Drill bit Proedge metal HSS-G 16.5 mm, single piece, Proedge by Milwaukee

Single Proedge metal drill bit HSS‑G with a 16.5 mm diameter, supplied as one piece. This high‑speed steel (HSS‑G) drill bit is designed for drilling through various ferrous and non‑ferrous metals at standard drilling speeds. The Proedge by Milwaukee construction provides wear resistance and consistent cutting performance for workshop and professional tasks. The shank is compatible with standard drill chucks and the bit can be used with cutting fluid to reduce heat and extend tool life.

Advantages

The HSS‑G material ensures durability and resistance to softening at elevated temperatures during continuous drilling. A precision ground flute profile supports efficient chip removal and stable cutting. Supplied as a single piece, the bit is ready for immediate use and fits most hand and bench drills. The 16.5 mm diameter enables larger metal holemaking without the need for step drills or multiple passes.

Suitable for

• Drilling holes in steel plates and structural metal components
• Creating clearance and bolt holes in metalwork
• Workshop or onsite fabrication and maintenance tasks
• Use in hand drills and drill presses with standard chucks

Key specifications

• Diameter: 16.5 mm
• Material: High‑speed steel (HSS‑G)
• Quantity: single piece
• Intended use: metal drilling (ferrous and non‑ferrous)
• Shank type: round shank compatible with standard chucks

How to use

Secure the drill bit in the chuck and tighten firmly. Mark and center‑punch the drilling location to prevent bit wander. Begin drilling at a moderate speed appropriate for HSS bits and the material thickness; apply steady pressure without forcing the bit. Use cutting fluid or coolant when drilling thicker or harder metals to reduce heat buildup and improve chip evacuation. After drilling, clear chips from the flutes and inspect the hole for burrs; deburr if required.

Usage recommendations

For best results, start with a smaller pilot hole when drilling very thick or hard metal, and use cutting fluid to extend tool life. Match drill speed to material: lower speeds for harder steels, moderate speeds for mild steel and non‑ferrous metals. Replace the bit when wear or chipping reduces performance to maintain hole quality and safety.
