لقمة تسوية علوية 2-1/2 بوصة مع شفرة كربيد قابلة للاستبدال – Whiteside SBU25-2 (طلاء AstraHP)

The replaceable carbide insert is the reason I picked this over cheaper solid bits, and it paid off immediately—swapped it out in under a minute after a nick.

Spent the weekend flattening a bowed oak panel for a tabletop and this bit left a glass-smooth surface with zero tear-out. The 1/2" shank ran true in my router table and the replaceable insert means I won't be tossing the whole thing when it dulls.
