Hazel R. ★★★★★

I was a little nervous buying a factory second, but the 1/2" shank seats solidly in my router collet with zero runout. For the price, this compression chipbreaker cuts cleanly through plywood—the geometry blemish is completely invisible during use.

Thomas ★★★★★

The cut quality on this 1/2" compression bit is impressively clean for a factory second—I can't spot any geometry issue at all. It's saved me a good chunk of money without sacrificing performance.

Natalie F. ★★★★★

Bought this as a factory second and honestly can’t spot any geometry issue—the cut on melamine was clean and chip-free. The 1/2″ shank fit snug in my router, and it’s performed just like a first-quality bit for half the price.
