This drill was designed for drilling work hardening 300 series stainless steels (except 303). Special thin web will penetrate work hardening stainless fast enough to cut beneath the chip which is hardening from deformation. These drill bits cut great in regular steel too. I guarantee that you'll love them. (Drill bit, jobbers length, black & gold 135 deg. 13/32" was posted and is owned by: Jenifer Brock) |
