Suppresing the burrs at the upper side surface of side machining Overturning the conventional wisdom that “it is natural for burrs to appear during cutting” and “it is natural to remove burrs after machining”, we took on the challenge of minimizing burrs. It is now possible to eliminate the secondary processing of deburring, which was previously required, resulting in shorter processing times and significant cost reductions. Suppression of top-side burrs by overwhelmingly using side-surface machining! R-edge (Radius edge) Reduced thrust force at exit of hole reducing the structure deformation Sharp edge cuts without leaving burr C-point (Center point) Reducing the hole expansion and uncutten burr from run out of the drills Burr height (Same diameter cross hole) Excellent burrless performance on not only for flat surface burr, but also on the cross hole which is difficult to deburring JINGASA left No need of next deburring process with no JINGASA left Almost same tool life as multipurpose Drill Reducing the burr even near of the end of tool life Realizes almost same tool life as multipurpose drill even burrless
