Description

Epoch TH Hard Drill Drills through hard steel up to HRC 65. TH coating and 4 guides with double margins make it last even longer. Concave cutting edge with high machinability and durability. EDM, which is generally used for drilling hardend Steel, has been the biggest impediment to réduction of maching cost. The Epoch TH Hard Drill for hardend Steel was developed to solve this problem. It also drills with improved stability and lasts much longer than conventional. The new Nano-composite coating material offers extraordinary heat resistance and hardness due to its new composite (layer consisting of Nano-crystal material. (Oxidizing temperature:1100 degrees centigrade, layer hardness:3600HV) Ensures long tool-life and good performance in hardened steel materials (45-60HRC). also pre-hardened steels etc. Generates less heat during cutting and is therefore well suited to dry machining conditions. TH coating has greatly improved surface hardness and heat resistance, resulting in machining efficiency and a longer life for the tool. Your problems can be solved by micro grain carbide with toughness and wear resistance. Four guides with double margins and a thick web enable stable drilling without run out the drill tip. The 20 degrees helix angle and concave cutting edge can constantly remove small chips. Chamfered cutting edge can moderate stress concentration at blind holes and corners of hole bottoms.
