Tin Coating Hss Annular Cutter High Efficiency Cobalt Annular Cutters For Metal Drilling

TiN coating is a very hard, gold coloured surface coating a few microns thick which is applied by means of a complex process, called Physical Vapour Deposition (PVD), by advanced modern equipment.
The coating is non-metallic and therefore reduces cold welding. In certain applications increased speed and feed rates can be achieved because of:
(a) The hardness of the coating.
(b) The reduction in cutting force required due to a decrease in friction between the tool and the workpiece.
Tool performance will deteriorate after re-sharpening.

Feature:

• Made of high quality & super tough high speed steel with multi-cut geometry for ply-cutting and lower friction to reach better endurance and less breakage ;
• Suitable for steel (such as T-brackets, large sheets), cast iron, non-ferrous and light metals;
• Optimized cutting edge geometry for increased cutting performances and reduced cutting forces;
• The effective cutting angles are designed for universal use in various sorts of steel;
• Improved removal of chips thanks to U-shaped recesses. The specific geometry of the recess reduces the thermal load on the HSS core drill as the heat created in cutting is removed with the chips to a very great extent;
• Reduction of the friction between the HSS core drill and the workpiece thanks to optimised spiral-shaped guide chamfers;
• Universal shank cutter is designed for use in any magnetic drill press.
