Drill bit Proedge HSS-G 15.5 mm for metal, single piece, model 4932500404

Proedge HSS-G 15.5 mm drill bit for metal is a single-piece cutting tool engineered for drilling accurate holes in ferrous and non-ferrous metals. Made from high-speed steel (HSS-G), this drill bit combines heat resistance and cutting-edge wear performance to maintain edge life during repetitive metalworking tasks. The 15.5 mm diameter delivers a precise hole size for mechanical assemblies, repair work and fabrication applications where consistent hole dimension is required.

Advantages

The HSS-G material offers good hardness and thermal stability, allowing faster cutting speeds and extended tool life compared with standard carbon-steel bits. A ground flute geometry ensures efficient chip evacuation and reduced clogging when working with metal, while a precise point geometry promotes accurate centering and minimized walking at drill start. Supplied as a single piece, the bit is ready for immediate use in hand-held drills, drill presses or production machinery.

Suitable for

• Drilling holes in mild steel, stainless steel and non-ferrous metals
• Workshop maintenance and repair tasks
• Professional trade use in metal fabrication and assembly
• Piercing material for mechanical installations and retrofit work

Key specifications

• Diameter: 15.5 mm
• Material: High-speed steel (HSS-G)
• Type: Metal drill bit, single piece
• Shank style: straight cylindrical shank compatible with standard drill chucks
• Application: Designed for drilling ferrous and non-ferrous metals

How to use

Secure the drill bit in a compatible chuck, ensuring correct alignment and firm clamping. Mark the drilling position and, if necessary, create a center punch indent to reduce walking. Use appropriate cutting speed and feed for the metal being drilled; apply cutting fluid for improved cooling and chip removal when drilling harder alloys. Maintain steady pressure and retract periodically to clear chips on deep holes. After use, clean the bit and store it in a dry place to prevent corrosion.

Usage recommendations

For best results, select drilling speeds and feeds appropriate to the workpiece material and thickness; use cutting fluid on stainless steel or high-strength alloys, and avoid excessive pressure that can cause overheating. Inspect the bit for wear before precision work and replace when the cutting edges become dull to preserve hole quality.
