Steven ★★★★★

I’ve been fighting tear-out on plywood for months, and this bit’s down-cut flutes finally give me clean edges without sanding. The AstraHP coating seems to help it glide through MDF with less heat buildup than my old uncoated bits.

Ryan Y. ★★★★★

The AstraHP coating really helps clear the chips on deep cuts, and I'm getting noticeably cleaner edges on my plywood projects. This 2-flute design pushes the waste down exactly as advertised, making my carve time more efficient.

Ellie ★★★★★
