لقمة قطع شق 3/8″ × طول القطع 3/4″ – Whiteside 1924 (مطلية بـ AstraHP)

Finally, a slot cutter that doesn't leave burn marks on hard maple—the coating makes a real difference in how smoothly it plunges. I cut about twenty feet of 3/8-inch slots yesterday and the bit still feels sharp as new.

The AstraHP coating really shows—even on a long run through MDF, the bit stayed cool and the slot walls came out glassy clean. I’ve used uncoated versions that gum up fast, but this one keeps cutting without that burning smell. Worth the extra few bucks for the smoother finish alone.

This bit cut through a stack of oak drawer sides with almost no burning, and the AstraHP coating really did keep the heat down on a long run. The 3/4-inch cut length handled my 3/8 slots in one pass without bogging down the router.
