The limits of diameter of twist drill of Titex whole hard alloy that covers with tiles Er spy company is developed is 3 - 20mm, bore deepness can amount to 8 times aperture respectively (Xtreme D8) with 12 times aperture (Xtreme D12) . With this company previously compare with photograph of broach of type whole hard alloy, cutting function and cutting tool life all have rise. The characteristic of this series broach includes: Use inside means of cooling feed flow and essence grind the chamfer that hold bit, raised the dependability of platoon bits. The most important is, optimized the geometry that get a tip appearance and used the double coating that get a tip (DPP coating) , the cutting tool life that ensured function mixes exceedingly good cutting to be achieved hard before. When be being machined with this broach, need not get treatment with centering already beforehand aperture, also need not use " peck attack " feed means. This broach suits to process all sorts of workpiece data, include cast-iron, common steel, alloy steel, tall alloy steel and all sorts of difficult treatment material. CNC Milling
