Drill Bit Proedge (MILWAUKEE) HSS-G 16.0 mm, metal, single piece

The Proedge (MILWAUKEE) HSS-G 16.0 mm metal drill bit is a single-piece, high-speed steel tool designed for cutting holes in steel and other ferrous and non-ferrous metals. Its HSS-G construction provides wear resistance and improved heat tolerance for conventional drilling machines used in workshops and professional settings. The 16.0 mm diameter delivers a precise hole size for metal sheets, tubes and machined components where accurate, clean edges are required.

Advantages

The single-piece HSS-G design ensures rigidity and reduced vibration during drilling, promoting straighter holes and longer tool life. Heat-resistant high-speed steel maintains cutting performance under elevated temperatures generated while working metal, reducing the risk of premature dulling. The geometry of the cutting edges produces cleaner hole walls and effective chip evacuation when used with appropriate speeds and lubrication.

Suitable for

• Drilling holes in steel sheets and plates
• Creating entry and clearance holes in metal tubing and structural components
• Workshop fabrications and on-site metal repair tasks
• General-purpose metalworking with conventional drilling machines

Key specifications

• Material: high-speed steel (HSS-G)
• Diameter: 16.0 mm
• Design: single-piece/solid shank
• Intended use: metal drilling (ferrous and non-ferrous)
• Compatible with: standard drill chucks on bench and hand-held drills

How to use

Secure the workpiece and mark the drilling position. Clamp the drill bit in a suitable drill chuck so it is straight and properly seated. Select an appropriate spindle speed and apply cutting fluid or lubricant when drilling harder metals to improve chip removal and reduce heat build-up. Use steady feed pressure and allow the drill to cut without forcing; periodically withdraw the bit to clear chips for deeper holes. After drilling, deburr as needed to obtain clean edges.

Usage recommendations

For optimal performance when drilling steel, use moderate speed settings, continuous light lubrication, and firm clamping of both bit and workpiece. Replace the bit or re-sharpen at the first sign of significant wear to maintain hole accuracy and prevent workpiece damage.
