The bit of series of GU/GT 500 DZ that Guhring company produces can be used at processing the of all kinds work such as blame iron metalloid, tall tensile steel, stainless steel, cast-iron, casting alloy and aluminium. The form of the chamfer that discharge bits that this series broach uses the figure of the tetrahedral geometry that get a tip with cutting powerful ability, broaden and mouth to pour a circle and coriaceous HSCO base material, increased the cutting function of broach and platoon bits capacity greatly. The PM steel matrix of broach of GT 500 DZ and FIREX coating combination make its have the characteristic of tall hardness, tall heat-resisting, with the medium dimension that processes work of tall tensile steel at batch Kong Shi has very high gender price to compare. Series of GU/GT 500 DZ includes a variety of type, suit all sorts of treatment machine tools, broach diameter limits is 1 ～ 14mm. CNC MillingCNC Machining
