Utilization of Toyota's Patent Technology: Drill 'Pentagon' with Anti-Missing Properties
Achieved by the "pentagonal pyramid chisel," which shapes the blunt angle part of the chisel edge at the center of the drill tip into a nearly flat pentagonal pyramid!
The "Pentagon" we handle is a drill that offers high hole position accuracy and excellent damage resistance even when used with high-hardness materials. While the tip angle of a typical chisel edge is about 140 degrees, the tip angle of the Pentagon's pentagonal pyramid chisel is about 170 degrees, making it closer to a flat surface. This results in a shorter tip length, which improves engagement with the workpiece! As a result, runout is reduced, and the stability of machining and hole position accuracy is enhanced! *Position tolerance within Φ0.013 【Features】 ■ Eliminates the chisel edge, resolving the runout caused by the chisel edge and achieving stable machining. ■ The multi-angular shape shortens the distance from the tip to the shoulder (tip length), allowing for faster stabilization and significantly improving hole accuracy and position tolerance. ■ Forming the chisel into a pentagonal shape suppresses the movement of the cutting edge, enhancing damage resistance. *For more details, please download the PDF or feel free to contact us.
