5/8″ Sperrholzfräser 19/32″ tatsächlich x 1/4″ Schaft – Whiteside 1027A (AstraHP beschichtet)

The AstraHP coating on this bit really helps the plywood edges stay crisp without burning, even on deep passes. Cuts cleanly through birch ply with almost no tearout.

The 19/32-inch actual diameter is spot-on for a snug fit in 5/8 plywood, and the AstraHP coating kept the edges crisp even on a long run of dadoes. Paired with my 1/4-inch collet, it tracked true with zero wobble, which is exactly what I need for repeatable joinery cuts.

Just finished running it through a test on some Baltic birch, and the cut is glass-smooth with zero chipping on the top laminate. The actual 19/32-inch diameter matched my measurements perfectly, so the dado fit the shelf tight on the first try. Really impressed with how cleanly the AstraHP coating
