Spot Drill Insert - 23 - 90°
23 Series
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
