Long Flat End Taper 
848L‑314
(Ø1.6 mm x 11.5 mm)
This Ø1.6 mm bur features a long 11.5 mm cutting surface, ideal for deep axial reductions and long‑wall crown preparations. The flat end creates a uniform shoulder while the taper guides the instrument to a consistent convergence angle. Its length allows full‑coverage preparations on elongated teeth without repositioning. Use this when extended reach and smooth margins are critical.

(Ø1.8 mm x 11.5 mm)
Offering a Ø1.8 mm diameter, this long taper bur delivers greater bulk removal with the same 11.5 mm reach. It maintains control while ensuring adequate clearance for thicker restorations. The flat end helps produce a defined shoulder, making it ideal for all‑ceramic crown preparations that demand accuracy over a long surface.
