HP-SH Burs | Short Shank Laboratory

Shop German-made HP-SH instruments — the shortened counterpart to Busch's standard HP (2.35 mm) laboratory shank, built for handpieces and micromotor attachments with limited chuck depth or working clearance. This collection spans carbide cutters, twist drills, grooving and parallel cutters, and wax-working instruments for denture, crown, and model fabrication.

Same 2.35 mm diameter as full-length HP, so any HP-compatible handpiece will run these instruments — the reduced overall length simply trims reach for close-quarters lab work and tighter handpiece geometries.
