1/8" 2-Flute Up Cut Spiral (unbranded)
No brand, no part number, no product page to check specs against — like U01 and T05 before it. Measured directly: 1/8” cutting diameter, 1/8” straight shank, 2 flutes, up cut. The shortest bit in the drawer at 1.53” overall.

Feeds & Speeds
For the X-Carve Pro and its 1.5 kW spindle. Same numbers as U05 and U07 — same diameter, same upcut geometry class, no vendor data to justify deviating from the house 1/8” upcut ladder.

Notes
Unconfirmed coating and grade, like every unbranded bit here. Treated as plain solid carbide by default since nothing on it says otherwise. If it turns out to run hotter or dull faster than the branded 1/8” upcuts, that’s the likely reason.
Maximum cut depth is 0.56” — short even by 1/8” standards, closer to D03/D04’s 0.5” than U05’s full 1”.
Plunges fine, same as any upcut — chips clear upward, no packing risk on a straight Z entry.
