This package contains all the tooling you need to be productive with your HiTorque deluxe mini lathe on the first day you own it. It assumes an existing quick-change tool post for which 3/8" tooling is ideal. If you are using a stock turret tool post, we recommend 5/16" tooling. The 1/2" capacity drill chuck includes a 2 Morse taper shank arbor for the mini lathe. This chuck is specifically designed for the mini lathe tailstock. The rated capacity of the drill chuck is 1 mm (0.039") to 13 mm (0.512"). (1212) & (1804) This set of indexable turning tools includes 5 indexable tools (AR, AL, BR, BL, E), inserts, a wrench, and extra screws. It comes in a wooden case. The carbide inserts are TCMT-21.51.

Heat treated, alloy steel shanks. (1246) The P1 parting blade is 1/16" x 1/2" x 4-1/2" and made from M2 HSS. These T-shape parting blades provide great side clearance.
