Title:
切り屑除去加工のための回転工具
Document Type and Number:
Japanese Patent JP4741276
Kind Code:
B2
Abstract:
The invention relates to a cutting tool preferably intended for drilling of the type that comprises a rotatable basic body (4), as well as a replaceable cutting part or loose top (5), which is rigidly connectable to the basic body via a male/female coupling, which includes, on one hand, a female-like groove (11) formed in a front end of the basic body (4), which groove is delimited by a bottom surface (14) and two side surfaces (15), and on the other hand a male part (22) insertable into the groove and protruding rearward from the loose top (5), which male part has an end surface (23) and two flank surfaces (24). In the front part of the basic body (4), a forwardly open slot (12) is formed, which separates two elastically deflectable legs (13) with the purpose of holding the male part (22) clamped in the groove (11), in one of said end and bottom surfaces (23, 14), a seating (28) being formed for the receipt of a projection (27) on the second surface. According to the invention, the seating (28) is larger or wider than the projection (27) in order to enable the male part (22) of the loose top (5) to move a short distance reciprocatingly in the groove (11) and thereby allow self-centring of the loose top.
