Abstract

728,532. Dental drills. DENTAL MANUFACTURING CO., Ltd. Jan. 13, 1954 [Jan. 26, 1953], No. 2258/53. Class 81 (2). A dental bur comprises a shank carrying an operative tip which is partially sheathed by a sleeve portion so that only a predetermined portion is exposed, the arrangement being such that an annular shoulder is present around the tip to limit the depth of penetration of the bur when in use. The operative tip 13 is brazed to a reduced portion 12 of the shank 10 and is partially sheathed by a sleeve 15 which forms an annular shoulder round the cutting teeth 14 of the tip 13. In an alternative construction (not shown) the sleeve portion is integral with the shank, the operative tip being inserted into the sleeve bore when the latter is hot so that, on cooling, the tip is securely held.
