Center Drills, Cobalt, Set of 5 (Numbers 1-5) - Main image
$13.97 $19.95 In stock

This set includes five different sizes of combined drills and countersinks, commonly called center drills. They are used to produce a center hole on a workpiece for turning between centers.
Center drills are also used to start drilled holes. Because they are very stiff they don't have a tendency to wander.
The set is high speed steel and includes sizes 1, 2, 3, 4, and 5. These are 60 degree center drills with a right hand cutting direction. Each center drill is made of ground high speed M42 cobalt steel for good wear resistance.

Matthew Z. ★★★★★

Finally, a set that covers every size I’ll actually need for the lathe. The cobalt material feels plenty tough, and the combined drill and countersink action saved me a step on the first brass job.

Stella ★★★★★

The set gives me all five sizes I need for lathe work, and the countersinks are ground cleanly enough to start a hole without wandering. The cobalt edge is holding up well so far, no chips or dulling after a few weeks.

Benjamin ★★★★★

The cobalt holds its edge noticeably longer than the high-speed steel ones I wore out before, and having all five sizes in one set means I never have to hunt for the right number mid-job. The #3 has been perfect for my lathe work, cutting clean and true every time.
