Solid drill bit SG

multi-purpose

Zero burrs at the internal diameter of internal thread 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. Realized Burr zero on internal diameter of internal thread Long tool life as same as multipurpose Taps Stable internal diameter accuracy lead Burr zero performance, even near to the end of tool life Reduces chipping and achieves same tool life equivalent to multipurpose taps Zero burr with cutting the internal diameter area on internal threadNo gap between thread root area of tap and pre-hole design acheves Zero burr!Chamfered rake face reduce the chipping of cutting edge by chip biting
