TWOoth Series: the 7901 carbide finisher, engineered as a disposable. Same geometry doctors already know — 12-blade, 1-piece solid carbide — rated for up to two autoclave cycles. Run it, autoclave it, run it again. After the second cycle, grab a fresh one. Premium-line performance at a per-bur price that makes retiring it easy.
SPEC: Shape: Flame finisher (7901) · Head: 0.9 mm · Cutting length: 3.6 mm · Blades: 12 · Shank: FG (friction-grip) · Construction: 1-piece solid carbide · Pack: 25 burs.
THE TWO-CYCLE RULE. Every TWOoth Series bur is rated for up to two (2) autoclave cycles with full cutting performance. After the second cycle the bur is spent — discard and use a new one. For high-cycle reuse, step up to the DentPS premium carbide line.
OPERATING SPEC — FG SHANK. Recommended operating speed is set by head diameter. Apply the bur to the surface only after reaching operating speed.

Light, consistent pressure — let the blades do the work. A water spray at the contact point keeps the cut clean and the carbide cool.
Item DDS7901 · TWOoth Series is a disposable line: priced and rated for up to two autoclave cycles, not for extended reuse or full mouth debonds. When debonding we recommend using on no more than one quadrant.
