Matthew Q. ★★★★★

Finally, a bit that actually keeps the top surface clean—the down-cut design made a huge difference on my walnut inlays, and the 1/8″ shank fit perfectly in my compact router.

Scarlett ★★★★★

I've been struggling with chip-out on thin plywood, and this down-cut bit finally gave me clean edges with no tear-out. The Astra coating seems to reduce heat buildup, and it's held its edge through several test runs. A worthwhile upgrade for anyone doing detailed inlay work.

Abigail J. ★★★★★

The down-cut flutes really do their job—chip evacuation is clean and the top edge of my hardwood pieces came out with zero fraying. The 1/8″ shank fits my compact router perfectly, and the 3/32″ cut length is ideal for shallow engraving passes.
