Abstract: Since the chip-breaking groove 30 is cut in the inner peripheral surface of the prepared hole 22 by compressing the chip-breaking tool 10 into the prepared hole 22 prior to the tapping process (the cutting process of the female thread) by the cut tap, the chip can be securely broken by the chip-breaking groove 30 and well discharged even in the case that the work 20 is made of the material having the high ductility. Accordingly, for example, as shown in FIG. 10, it is possible to prevent a lot of long connected chips from entwining the tap, it is unnecessary to monitor the tapping work, and it is possible to achieve a complete automation (an unmanned work). Further, it is possible to inhibit the cut tap from being broken due to the pinching of the chip, and it is easy to execute a treatment such as a chip cleaning or the like.

The other cavity has a plurality of blades pivotally captured therewithin in such a manner that the blades are radially spaced about the axial centerline of the tool with the cutting edges thereof disposed at an appropriate angle so that when the inlet end of a torch tip is placed within the cavity and relative rotation effected between the torch tip and the tool, material is simultaneously removed from both the seats located at the inlet end of the torch tip.

Abstract: A machine tool for performing a plurality of operations on a workpiece, i.e. a transfer machine, has two tools which are alternatively presentable to the workpiece and which are mounted coaxially for common rotation on the front end of a spindle. The spindle is rotatably mounted in a sleeve which is mounted for axial displacement in a fixed head. The displacement of the sleeve, which may be effected by a rack and pinion, serves to feed a first one of the tools to effect its machining operation. A front portion of the sleeve projects beyond the head and carries an actuator for causing the second tool to move axially relative to the first. After machining by the first tool, operation of the acutator serves to initiate displacement of the second tool to commence its machining operation. To provide a common rotary drive for both tools, the spindle or a prolongation thereof extends rearwardly of the head and is splined to a drive pulley mounted in an axially fixed position on the rear of the head.

The drill bit is of the twist type and has at least two longitudinal flutes joined by a web and separated by an equal number of longitudinal lands. The deburring bit has a number of radially extending cutting elements which project radially outwardly from adjacent the bottom of each flute to substantially beyond the diameter of the hole. At the bottom of the flutes, the radially extending cutting elements are spaced to pass the web of the drill bit axially therebetween and to engage the flutes when the drill bit is rotated.

Abstract: A boring tool assembly performs both the rough and finish cutting operations upon a metal work piece without power activation or manual adjustments of the tool units between the cutting strokes. The assembly includes a boring bar having a pair of fixed, diametrically opposed rough cut tool units, and a pair of retractable finish tool units diametrically opposed to each other also. The tool units are automatically operative in response to either the rough cut or the finish cut of the boring tool assembly. Spring biased plungers normally pivot the finish cutting units toward their cutting positions. During the initial or rough cutting operation, forces act upon the heel of the finish tools causing retraction from the cutting position. This is possible due to the cutting edge configuration and angle of orientation of the tools, the positioning of the tools on the trailing side of the boring bar centerline, and the direction of advancement of the boring bar.

Abstract: A device is provided for creating recesses for road surface markers in road surfaces which makes initially a cut sufficient to stabilize the device in the desired position and then fragments and discharges core material within a circular cut defining the recess.
