Joseph O. ★★★★★

Finally got to use this on a deep rebate job and the extra 1-5/8 cut length saved me from switching to a different setup. Cuts cleanly through the hardwood without any burning, even on a long pass.

George A. ★★★★★

That AstraHP coating makes a real difference on long cuts like this — the bit stays cool and doesn't gum up even after a heavy pass through plywood. The 1-5/8-inch reach got me into places my old trim bit couldn't touch, and the cut stayed clean the whole way.

Michael ★★★★★

The coating on this bit really does keep it running cooler, even during long sessions of flush-trimming thick material. Cuts cleanly through hardwood without leaving burn marks, which was a pleasant surprise.
