Abstract

1,254,522. Percussion drills. R. D. ADAMS and I. J. SHARLAND. 14 Nov., 1968 [20 Aug., 1968], No. 13525/70. Divided out of 1,254,521. Heading B4C. A tool bit for use in a percussive drill comprises a shank 2 encircled by at least one band of polymeric material retained by a sheath 3. Polymeric materials having high vibration damping properties e.g. copolymers of vinyl acetate, polyvinyl chloride, butyl rubber, L.D.- 400 and modified polypropylene, may be injected through holes 14, 15 into annular chambers 11, 12 between the sheath 3 and the shank 2. Alternatively strip polymeric material may be wound round the shank, coated with adhesive and the sheath slid over it. The sheath is preferably of mild steel, shrunk on to a hard steel bit.
