Stainless drills
Silmax previews a new line of drills with internal lubrication holes 3XD, 5XD and 8XD (IC) specifically for stainless steels.
The drills are designed to deliver the highest reliability in the most demanding and fully automated tasks.
The essential geometries developed offer smooth and consistent chip removal and the tool surfaces, made super smooth by specific automated processes, ensure low torsional stresses and precision even on carbon steels, cast irons, titanium alloys and super alloys.
The drill essential design gives a steady and robust chip removal. The extremely smooth tool surfaces keep the torsional stresses low and keep high hole precision also on carbon steels, cast iron, titanium and superalloys. Latuma supersmooth coating guarantes heat reduction, better chip evacuation and increased tool life.
Other diameters on request.
