• Special threads are used to strengthen the fastening force.
• A cone face newly attached ensures high precision of run-out tolerance.

Center Drills

YAMAWA center drills realize a good combination between chip flow at drill portion and that at countersink portion. Their flutes can fully accommodate chips and work well to eject the chips.

• YAMAWA center drills have the cutting edges on both ends, and have spiral flutes.
• Owing to good chip ejection, such troubles become less as the tools break due to chip clogging.
• Considering drill strength, we have minimized the drill length. Further to compensate the weakness at connecting point between drill and countersink, the connecting point has R which radius is within the back-taper of the drill. They also have a wide line-up.
