Drill bit Proedge 18.5 mm HSS-G for metal, model 4932500410, 1 piece

Proedge 18.5 mm HSS‑G drill bit for metal is a single cutting tool manufactured for precise hole-making in steel and other ferrous materials. The bit features high‑speed steel with ground geometry (HSS‑G) to deliver consistent cutting performance, improved wear resistance and dimensional accuracy for an 18.5 mm hole. It is supplied as one piece and is suitable for both manual drilling and machine-mounted operations in metalworking tasks.

Advantages

The HSS‑G construction provides a hard, wear‑resistant cutting edge and stable geometry that reduces vibration and improves hole quality. Ground flutes and point geometry offer accurate centring and efficient chip evacuation, which helps maintain cutting performance over repeated use. The single‑piece supply simplifies inventory and selection when an exact 18.5 mm diameter is required.

Suitable for

• Drilling through mild and hardened steels
• Metal fabrication and assembly work
• Maintenance and repair tasks requiring precise 18.5 mm holes
• Use in drill presses, pillar drills and hand-held drills with appropriate chuck capacity

Key specifications

• Diameter: 18.5 mm
• Material: high‑speed steel (HSS), ground geometry (HSS‑G)
• Intended application: metal drilling
• Flute type: ground flutes for chip removal
• Supply quantity: single piece

How to use

Select a drill or drill press with a chuck capacity that secures an 18.5 mm shank or use an appropriate adapter. Mark and centre‑punch the drilling position on the workpiece to prevent wandering. Use appropriate cutting speed and feed for the workpiece material; apply cutting fluid or coolant when drilling steel to extend tool life and improve surface finish. Start at low speed to establish the hole, then increase speed as appropriate while maintaining steady feed and coolant. Clear chips periodically to avoid clogging the flutes.

Usage recommendations

For best results when drilling steel, use cutting fluid and moderate cutting speeds matched to the material hardness. Secure the workpiece firmly and use a pilot drill for deep or precise holes where necessary. Inspect the cutting edge before use and replace the bit when wear affects hole quality.
