Busch Carbide Bone Taper (Cone) Pointed Cutter | Busch No. 166A 021 – HP | Pack of 2

Busch No. 166A 021 – HP is the straight-handpiece member of the 166A family: an A-Cut, low-vibration carbide taper (cone) pointed bone cutter with a 2.1 mm (ISO 021) head on an HP shank. Supplied as a pack of 2 and manufactured in Germany by Busch & Co. GmbH, it is the reference to select when your bone reduction is done with a straight surgical or laboratory handpiece rather than a contra-angle.

Why choose the HP version

Straight surgical handpieces are typically used where there is open access and the clinician wants a rigid, in-line instrument — ridge reduction, tuberosity work, or bench-side laboratory tasks — running up to roughly 40,000 rpm depending on the motor. Pairing the 2.1 mm A-Cut head with the HP shank suits larger-volume bone removal at these sites; the RA and RA-L versions cover the same head in latch-contra-angle form.

Also available: No. 166 021 – RA, No. 166A 021 – RA-L, No. 166A 021 – RA, No. 166 021 – RA-L.
