Would you prefer linear flats for easy "Z" Axis adjustment? Linear Flat Tools by AB Tools, Inc. are for any size shank. Having received so many returned tools with hand ground flats or no flats and deep screw marks on the shanks, we developed these. Using industry standard TPMT2-2 inserts, these will cut flats to Weldon shank flat specifications or longer linear flats in most part materials. Proudly made in the USA by AB Tools, Inc.
