US No. 700L Busch Carbide Tapered Fissure (Cone) Long Bur | Busch No. 33L 010 – Crosscut – HP | Pack of 6
Busch No. 33L 010 – HP (US No. 700L) is the straight-handpiece version of the crosscut carbide tapered fissure (cone) long bur: a 1.0 mm (ISO 010) long cone head on an HP shank for laboratory and surgical straight handpieces. Busch & Co. GmbH makes it in Germany and this listing is a pack of 6; the friction-grip 33L 010 FG carries the same head for turbine use.
Why choose the HP version
The HP shank is typically the choice for dental laboratory work — trimming acrylic, refining crown and bridge frameworks and detailing models — where a straight handpiece running up to roughly 40,000 rpm gives long, controlled strokes. The long crosscut cone head reaches into narrow embrasures and grooves in these bench-side tasks. If you need the same 700L geometry in a high-speed turbine for chairside cavity preparation, choose the FG version instead.
Also available: No. 33L 010 – FG.

The long tapered fissure head reaches further than the standard figure while still cutting convergent walls and tapered grooves. A 1.0 mm head works in narrow interdental and clasp areas where a larger head cannot reach. Its crosscut (double-cut) toothing removes stock quickly and clears chips well, so it is a shaping rather than a finishing cutter.
