guhring's your wor D-WIDE PARTNE JIS›eco<tap just smart! special cutting edge preparation for perfect coating achesion new flute and threed geometry regarding rake angle, relief and chamfer design, for higher and stable tool life the TiCN coating protects the cutting edges from heat and wear for longer tool-life ■ The Eco Tap achieves up to double the tool-life compared with uncosted tools ■ The coating technology makes it possible to double the cutting speed > coat reduction Because of its superior geometry and the special cutting edge proparation the ecotep works under all conditions. Therefore ecoteps manage stand drills as well as modern CNC centers. With the TICN coating the ecotap achieves up to double the tool-like compared with uncoated tools. But there is more to come. The ecotap doubles also the cutting speed. It is therefore especially economic thanks to latest Günring grinding and coating technology – made in Germany for highest quality. JIS Eco Taps
