مثاقب مركزية، كوبالت، مجموعة من 5 (الأرقام 1-5)

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.

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.

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.
