Drill bit AWTools HSS M2 16.5 mm – single piece, metal drilling

AWTools HSS M2 16.5 mm single-piece metal drill bit is engineered for conventional drilling in steel and other ferrous and non-ferrous metals. Made from high-speed steel (HSS M2), this 16.5 mm diameter bit delivers the hardness and heat resistance required for routine metalworking operations. Supplied as an individual bit, it is compatible with handheld electric drills and drill presses for maintenance, repair, and workshop tasks.

Advantages

The HSS M2 composition provides good wear resistance and thermal stability during extended drilling cycles in metal. A single-piece design ensures rigidity and reduced vibration for straighter holes. Its 16.5 mm diameter is suitable for medium-sized holes commonly needed in fabrication, repair and installation work. The bit’s geometry is optimized for metal cutting to reduce chatter and support efficient chip evacuation when used at appropriate speeds and with cutting fluid.

Suitable for (tasks / use cases)

• Drilling holes in mild steel, stainless steel, aluminium and other metals
• Workshop fabrication and assembly
• Maintenance and repair tasks requiring medium-diameter holes
• Use with handheld drills and drill presses

Key specifications

• Material: High-Speed Steel (HSS M2)
• Diameter: 16.5 mm
• Type: Single-piece spiral twist drill bit
• Application: Metal drilling (ferrous and non-ferrous)
• Compatible with: Standard drill chucks (check chuck capacity)

How to use

Secure the drill bit in the chuck ensuring proper centring and tight clamping. Select an appropriate spindle speed for the material being drilled—lower speeds for harder metals and higher speeds for softer metals—consulting standard drilling speed charts if needed. Use steady feed pressure and avoid excessive force that can overheat the bit. Apply cutting fluid or coolant when drilling steel or stainless steel to prolong bit life and improve chip removal. Withdraw the bit periodically on deep holes to clear chips.

Usage recommendations

Inspect the bit before use for visible damage or dulling; replace if worn. Match drill speed, feed and coolant to the workpiece material. Use a correctly rated chuck and ensure machine stability to achieve accurate results and extend tool life.
