طقم بت السطح بقص لأعلى 2-1/2 بوصة – Whiteside SBU25-2KIT (مطلي بـ AstraHP)

Cutting through some gnarly white oak for a tabletop, and this bit chewed through it with zero burning or chattering. The Astra coating really helps keep it clean, and the finish after surfacing was nearly ready for sanding.

I was worried about tear-out on maple, but the up-shear geometry left an almost glassy surface on my test pass. The AstraHP coating is holding up well after a solid afternoon of flattening walnut slabs.

The AstraHP coating on this bit is a game-changer—chip evacuation stayed clean even on a dense hardwood flattening pass, and the finish came out smooth enough to skip sanding. I’ve used cheaper up-shear bits that gummed up mid-job, but this one held its edge the entire session.
