A hart bur cuts the 90 degree seat a stone drops into, and this kit covers that job across ten graduated sizes. The Fox-Komet H253B Carbide Hart 90 Degree Bur Kit is built for demanding hard alloys: carbide construction suits it to setting work and seat cutting in white gold, platinum, and steel, the materials that dull standard high-speed steel burs fastest. Sizes run from 0.90mm to 1.80mm in 0.10mm steps, a finely graduated selection for precise stone-seat work, and every bur mounts on a 3/32" shank that fits standard flex-shaft handpieces and pendant motors.
