YIH TROUN Spot Drill features sandwich plug-and-clamp construction as well as special design with tapered key. It stays eccentricity ± 0.008mm, approaches almost zero eccentric in stationary status. A precise spot drill helps in great saving of tap breakage. Special carbide grade C350 / B350 has great strength on insert cutting edge especially in the condition of high feed machining, with it's 2 effective cutting edges, the machining efficiency increased dramatically 300% - 1000%. Multifunctional purpose can be used in spot positioning, round-hole chamfering, side corner chamfering, V-shape grooving and engraving. Features Patented design in almost zero eccentric, maximum eccentricity ± 0.008mm. Double effective chamfering teeth, redouble processing efficiencies. Designed with unique geometry angle on the center engage point which decrease cut resistance and eccentricity. It gives excellent spot precision and long tool life. Multifunction: Spot positioning, corner chamfering, V-shape grooving and engraving.
