لقمة تقريب حواف غاطسة مقاس 1/4″ × ساق 1/4″ – طلاء AstraHP – Whiteside (2052)

I’ve been running this bit through some dense CNC jobs and the 1/4-inch shank feels rock solid in the collet, zero chatter on the plunge cuts. The AstraHP coating is holding up noticeably better than my uncoated bits after a couple of hours of use.

The AstraHP coating on this bit made a huge difference in my CNC runs—the chips cleared cleanly and there was zero heat buildup even on a longer session. The 1/4-inch shank fit my router collet perfectly, and the plunge action felt smooth and controlled right out of the box.

Cut some test pieces in walnut and the AstraHP coating really helped keep the bit from gumming up, even at higher feed rates. The 1/4-inch radius came out glass-smooth with zero burning.
