HI-NOX HSS M2 spiral drill with right-hand cut and cylindrical shank. The drill has a 130° point angle with a polished section and a special polished spiral with "Quick Cut" geometry that produces small swarf. The reinforced core, reinforced spiral shoulder and a specially shaped short spiral notch make the bit extra robust and support optimal chip evacuation. The tool is highly heat-resistant and delivers reliable cutting performance, especially in stainless steels, but is also suitable for all steels, cast iron and cast steel. It is intended for energy-efficient, effortless drilling with cordless and mains-powered machines.

Advantages

The HSS M2 material and HI-NOX coating (black/uncoated appearance) provide high heat resistance and long tool life. The 130° point angle and polished cutting sections reduce cutting forces and improve centring and penetration. Quick Cut spiral geometry produces smaller, manageable swarf and aids chip removal. Reinforced core and shoulder increase torsional strength and resistance to breakage, making the bit suitable for demanding drilling tasks.

Key specifications

How to use

Clamp the cylindrical shank securely in the drill chuck. Select an appropriate spindle speed for the work material (lower speeds for stainless steel, higher for mild steel) and apply steady, even feed pressure. Use cutting lubricant when drilling stainless steel or other hard-to-cut materials to reduce heat and improve chip evacuation. Withdraw the drill periodically when drilling deep holes to clear swarf and prevent clogging.

Recommendations

For best results in stainless steel, use moderate speed, steady feed and a suitable cutting fluid. Ensure the drill is correctly centred before applying full feed to avoid walking and reduce the risk of breakage.
