This special boring tool was made for use with our Turner’s Cube kit.
It is used to undercut the sides of the cube and the tip of the boring tool is shaped to undercut the final bore diameter to release the inner cubes.
The special undercut boring tool P/N T3061 is used to release the inside cubes.
These high-speed steel cutting tools are designed specifically for use with the Sherline boring head and feature a 3/8" (9.5 mm) diameter shank.
P/N 3061 is suited for holes with a minimum diameter of 1/4" (6.4 mm) and a maximum cutting depth of 0.600" (15.2 mm).
P/N 3063 works with a minimum hole diameter of 5/16" (7.9 mm) and provides up to 1.00" (25 mm) of cutting depth.
P/N 3064 also fits a 5/16" (7.9 mm) minimum hole but offers an extended 1.5" (38.1 mm) reach.
If needed, the tools can be ground to fit smaller hole diameters. They may also be used in the 3/8" round-hole tool post on a lathe for boring operations. Each tool includes a ground flat on the shank to provide a secure surface for the boring head setscrew.
