Burnishing Drill

Burnishing Drills feature a four-edge design, greatly improving the straightness of holes.

With two extra burnishing edges, they not only smooth out the hole but also give a better surface finish. Together, these features increase the precision and look of the drilled holes, ideal for high-quality finishing.
