Customer Reviews (4.6 / 5 · 5 reviews)

Richard R. ★★★★★

These AstraHP coated inserts are lasting noticeably longer than the uncoated ones I used before, and the fit on my SB25 cutter head was perfect. The surface finish on my workpiece came out glass-smooth with no tear-out.

Jacob ★★★★★

I was worried these inserts would be inconsistent, but every one of the ten cut cleanly and seated perfectly in the SBU25 body. The AstraHP coating seems to reduce friction noticeably, making passes smoother than with uncoated bits I've used before.

Ruby X. ★★★★★

Felt a little hesitant spending for inserts instead of a whole new bit, but these cut true and the AstraHP coating has held up nicely through some serious oak flattening. Exactly what my SB25 body needed, and the pack of ten means I won't be reordering anytime soon.
