Document Type and Number:

Japanese Patent JP3819450

Kind Code:

B2

Abstract:

PURPOSE: To reduce the wear of a driving member by providing an axially molding part for an additional driving part on the end surface side of a stepped part.
CONSTITUTION: In a tool having a working shaft 11b having a diameter larger than the diameter of the integral shaft of an insert end part 11a, a molding part having the form of mutually reversed driving pockets 27, which is opened radially outward, is arranged on the end surface side of a stepped part 16 formed by this difference in diameter. The driving pocket 27 must be formed in a position as deep as possible of the section 11b of the tool shaft 11, and it is constituted with a diameter larger than the hole 14 of a tool receiving part 13 or the insert end part 11a of a tool 12 similarly to a driving tooth 28. Accordingly, the driving tooth 28 never obstructs the insertion of a shaft end 19a into a tool holder 10.
