• Powerful performance
• Quality

Short multi grade twist drill with cylindrical shank Multi-problem solver ATN - AlTiN is made of aluminium (Al), titanium (Ti) and nitrogen (N). The layer has a much higher thermal insulation (900..C) and hardness (3300 3500 HV) as the TiN layer (550..C/2300 HV). It is mainly used in high wear and/or at high temperature stresses, e.g. with insufficient lubrication or without cooling. ATN layer combines the advantages of TiN, TiAlN and TiCN. In general all-round layers have the disadvantage that they cannot provide top performance, nut not the ATN layer. The ATN layer will replace in the long term the conventional three layers. higher wear protection than TiN, additionally high heat resistance, universal applications up to 4 times higher performance than TiN, possible performance improvement, higher cutting speed and feed rates, higher tenacity, Applications: All-round layer, minimum quantity lubrication, machining of aluminium, great for deep holes Usage: for medium and long-chipping materials with a tensile strength up to a maximum of 1200 N/mm2, for AI/copper/AlSi alloys, soft bronze, electrolytic copper, tough brass, stainless steels, V2 A and V4 A steels, titanium, titanium alloys Packing: Quadro pack of 10 pieces up ..; 10; 5 each from ..; 10.2; 1 each from ..; 14.5
