Drill bit Proedge HSS-G for metal 17.5 mm – 1 pc (MPN 4932500408)

Proedge HSS-G metal drill bit, 17.5 mm diameter, single piece. Designed for metalworking, this high-speed steel (HSS-G) drill bit offers the hardness and wear resistance required for drilling through ferrous and non‑ferrous metals. The bit is intended for use with handheld drills and drill presses for through holes and general metal fabrication tasks in workshops and on‑site environments.

Advantages

The HSS-G material delivers high hardness and thermal resistance during continuous drilling operations. A precision ground cutting edge ensures consistent hole quality and reduced chatter when used in suitable drilling equipment. The single-piece design provides rigidity and reliable concentricity, helping to maintain hole diameter accuracy over repeated use.

Suitable for

• Drilling through mild steel, stainless steel and non-ferrous metals
• Workshop fabrication and maintenance tasks
• On-site drilling with handheld electric drills
• Use in drill presses for controlled, straight holes

Key specifications

• Material: High-speed steel (HSS-G)
• Cutting diameter: 17.5 mm
• Design: Ground flutes and single-piece construction
• Intended use: Through holes in ferrous and non-ferrous metals

How to use

Secure the drill bit in the chuck of a handheld drill or drill press, ensuring proper tightening and alignment. Select an appropriate cutting speed and feed rate for the metal being drilled; slower speeds are generally recommended for harder materials. Use cutting fluid or lubricant to reduce heat and prolong tool life, and clamp the workpiece to prevent movement. Clear chips regularly to avoid clogging the flutes and to maintain cutting efficiency.

Usage recommendations

For best results when drilling thicker or harder steels, use a drill press where possible, apply an appropriate cutting lubricant, and reduce speed to minimise heat build-up. Inspect the cutting edge periodically and replace the bit when wear affects hole accuracy or increases drilling force.
