This is the Tamco/Toku front head – complete 1-1/8″ part number 41024153D, Crowder SKU TK-41024153D. It is the business end of the tool it locates the tool steel and absorbs the impact reaction, so bore wear here shows up as a loose, rattling shank.

If you are working from a machine rather than a part number, start at the full diagram library, or send us the model and serial and we will match it. Machines themselves are on the Toku tool catalog. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
