<p>A clamping shoe (103) rests with its underside (104) on the blade front side and has bores for a clamping screw shank and head (123). Below the clamping shoe a separate counter fixture (62) has its underside displaceable on a radial bearing plane (18) of a reamer head driving radial adjustment. It has a straight holding bar (66) for supporting the blade and an oblong through-hole (82) in its centre region, traversed by the clamping screw (123) and whose longitudinal extent is radial. The clamping shoe (103) has its bores similarly oblong. The clamping shoe (103) and counter fixture (62) are connected by a contour locking device (84,107) whose effective locking surfaces extend perpendicularly to the radial direction.</p> |
