Punta elicoidale KWB 258685 rotazione destra 1 pz.

HI-NOX HSS M2 spiral drill bit, right-hand cut with cylindrical shank, uncoated black finish and a 130° point angle featuring a special polished section. The drill is designed with a reinforced core, strengthened spiral shoulder and a specially shaped short spiral notch to provide robust construction and efficient swarf evacuation. The Quick Cut spiral geometry produces small swarf and the tool is optimized for high heat resistance and cutting performance, particularly in stainless steels but also suitable for all steel types, cast iron and cast steel. Supplied as a single KWB 258685 unit for effortless, energy-saving drilling with cordless or mains-powered machines.

Advantages

The spiral cutting drill offers improved cutting efficiency and reduced friction through its Quick Cut geometry and polished sections, enhancing chip control and tool life. Reinforced core and shoulder deliver extra robustness for demanding drilling tasks, while the 130° point angle ensures reliable centring and penetration. Its high heat resistance makes it suitable for prolonged use in stainless steels and other hard materials.

How to use

Secure the cylindrical shank in the drill chuck and set the drill machine to an appropriate speed for the material being drilled. Use steady feed pressure and allow the drill to cut without excessive force to ensure correct chip formation and removal. For stainless steels and harder materials, reduce speed and increase coolant or lubrication as needed to manage heat and prolong tool life. Clear chips periodically when drilling deep holes.

Recommendations

For best results when drilling stainless steel, use cutting fluid, operate at lower speeds, and avoid excessive axial force. Inspect the drill regularly and replace if wear affects centring or chip evacuation.
