Abstract
Abstract An interchangeable tool mounting device particularly adapted for use with turret lathes in retaining center drills in a desired position. The device includes an elongated body portion having first and second coaxial tool holder receiving passages extending inwardly from the ends thereof. Tool holders which are dimensioned to be closely received in the tool holder receiving passages have tool element receiving passages extending coaxially inward from the ends thereof which are adapted to closely receive different standard sized center drills. By varying the relative disposition of the tool holders within the body portion, a particular sized center drill may be placed in an operative position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
250 words
A tool holder comprising; an elongated substantially cylindrical body member having opposite end portions and a longitudinal axis, a bore extending substantially coaxially into said body mEmber from one of said end portions thereof, mounting means on said body member for mounting said body member to a machine, a plurality of substantially cylindrical tool holders having longitudinal axes and opposite tool holder end portions, tool holder bores extending substantially coaxially into said opposite tool holder end portions, each of said tool holder bores having a different diameter, said tool holders being receivable in said bore in said body member with said longitudinal axis of said body member substantially coincidental with said longitudinal axes of said tool holders, each of said tool holders having a substantially common predetermined length and opposite ends, said bore in said body member having a bottom, releasable securing means for securing one of said tool holders in working position within said bore in said body member with one of said ends of said one tool holder extending outwardly from said bore in said body member and the other of said ends positioned in said bore in said body member, the distance from said other end of said one tool holder to said bottom of said bore in said body member being at least as great as said predetermined length of said tool holders, said mounting means comprising an elongated tapered mounting shank extending coaxially of said body member from the other of said end portions thereof.
Claim 2
Dependent Claim
