Abstract

1432612 Drills HAWERA PROBST KG HARTMETALL - WERKZEUGFABRIK RAVENSBURG 9 April 1973 [7 April 1972] 16834/73 Heading B3C A drill comprises a shank 1, Figs. 2, 3, fluted at 2, and a hard metal cutter blade 14 detachably held in a transverse slot 5 in the head 3 of the drill by a pin 26 which is located in transverse bores 8 and 23 in the drill and blade respectively the blade being located in a direction transverse to the drill axes by having the bottom of slot 5 shaped to correspond with the shape of the end of the blade. The two end sections 9, 10, Fig. 4 of the flute are lccated symetrically relative to the blade, and in a modification, Fig. 5 (not shown), there are four groove sections (9a), (10a). Cutter blade 14 is of hexagon shape, is indexable, and a rubber sleeve 24 has an eccentric bore 25, so that when the blade is secured by pin 26, it is urged into a Vee-shaped bottom of slot 5. The cutter blade may only have two cutting points, Figs. 6, 7 (not shown), or it may have a single cutting point 19c, Fig. 10, and be located by a rectangular or circular projection 20c. In a modification, the cutter blade 14d, Fig. 11, is held in the drill by a pin 26d which is located in a part bore 8d in the drill, and engages the bottom of a recess 23d in the blade, so as to urge the latter towards the bottom of slot 5d. In this latter embodiment flutes 2 are replaced by flats (2d) Fig 12 (not shown). In a further embodiment the seat 29, Fig. 13, for the cutter blade is a hard metal insert which may be soldered, pressed, or welded to the drill.
