Combined drills and countersinks, commonly called center drills, 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.

Victoria ★★★★★

I needed a clean 60-degree center point for my lathe work, and these HSS bits start the hole without any wandering. The countersink portion matches perfectly with the drill diameter, making prep fast.

Eli L. ★★★★★

I was a little worried these wouldn't be as sharp as my old set, but the HSS material bites into steel cleanly without chattering. The combined drill and countersink profile saved me time on starting holes for my lathe work.

Brian ★★★★★

The individual sizes in this set are a lifesaver when I'm switching between different workpieces, and the combined drill/countersink design means I don't have to swap tools mid-task. They cut cleanly on my lathe, so I'm pretty happy with the purchase.
