US No. 8SXM Busch Carbide Round Bur | Busch No. 1SXM 023 – SXM-Cut – RA-L | Pack of 2
Pack of 2. Busch No. 1SXM 023 – RA-L (US No. 8SXM) is the long-shank version of the SXM-Cut carbide round (rosehead) bur: a 2.3 mm (ISO 023) fast-cutting, low-vibration head on a long latch-type (RA-L) shank for slow-speed contra-angle handpieces. Made in Germany by Busch & Co. GmbH, it differs from the standard 1SXM 023 RA only in working length and pack size.
Why choose the RA-L version
The long RA shank is typically chosen when a 2.3 mm rosehead has to reach deep — bulk excavation of caries in a deep posterior cavity, opening a pulp chamber on a molar with a long clinical crown, or working past a rubber-dam clamp — while the contra-angle head stays clear of the field. It runs at low speed in a standard latch handpiece, and the SXM-Cut geometry supports fast excavation with reduced vibration.
Also available: No. 1SXM 023 – RA (pack of 6).
