Surgical Length | FG-LG 21 mm & RA-L 26 mm Burs

Surgical length burs — Busch’s FG-LG (21 mm overall) and RA-L (26 mm overall) shanks, versus the 19 mm and 22.5 mm standards — extend reach for posterior access, deeper preparations, and surgical visibility, keeping the handpiece head clear of the working field.

These lengths carry the same head geometry as their standard siblings — the L suffix on the Busch number is the only change, so your technique transfers directly. Need even more reach? See the extra-long 25 & 34 mm collection.

FAQ

What is a surgical length bur? A bur with an extended shank that reaches deeper sites — third molar sectioning, bone work, deep caries — while the handpiece head stays clear of tissue. This collection covers the 21 mm FG and 26 mm RA lengths.

Do surgical length shanks fit standard handpieces? Yes — FG-LG seats in standard turbine chucks and RA-L in standard latch contra-angles; only the exposed length differs.

Where are these instruments made? Every instrument in this collection is manufactured by Busch & Co. in Engelskirchen, Germany — an ISO 13485-certified specialist in rotary precision instruments since 1905 — and ships fast from our US warehouse.
