3/8" SQUARE SHANK SNAP RING GROOVE CUTTER KIT
Product Description
This is a snap ring groove cutter kit for use with line boring equipment. This kit works with line boring equipment that uses 3/8 inch square tool ports in the boring bars.
(Some photos shown of examples are of my other kit that has 1/2 square toolholder, the operation of either kit is the same the tool holders are just different)
The tool works by placing a piece of 3/16 HSS that has been ground to the needed dimensions, into the 3/8 square tool holder. The bit is then locked into place with the small setscrew on the side. A spring is then placed in from the other end and then a set screw screwed in to apply pressure on the spring, to then pressure the cutter bit out to cut.
The tool holder is then placed in the bar and bar is moved into the bore and set to where the snap ring groove needs to be. Then lock the tool holder into the bar by tightening the bar setscrew with the cutter bit placed almost touching the bore. Then the small setscrew on the side is released (recommend removing it completely) and then the motor is started and the groove cutting begins.
After the groove is cut the set screw in the side is reinstalled to lock the cutter bit back to the tool holder. The tool holder is then released by the set screw in the boring bar so it can be slid back and then the bar moved out of the bore.
The kit comes with 2 different length tool holders (1-1/2" and 2-1/8") this allows the kit to cut snap rings in bores up to approximately 4" in diameter (when using a 1-1/4” bar) The kit comes with 3 different strength springs to choose from. There is a set of shorter springs for the short tool holder and a set of longer springs for the long toolholder. This is a little bit of trial and error the first use to find a combination that works good for the width of groove your cutting and the amount of pressure you place on the spring with the setscrew. The kit comes with (2) 3/16” Cobalt/HSS tool blanks that get cut down to your needed length and then the end ground to the required dimensions for the groove your cutting. (See photo showing example of a bit that has been ground) Also in the kit is all the needed set screws along with extras and the needed hex key wrenches for those set screws.
The tool is very compact to work in very tight areas.
Kit comes in a small container to store all parts as seen in the photos.
