The Hole Saw Transfer Punch was designed by Tucci Hot Rods to help find the perfect center for a hole or radius when larger than a standard transfer punch kit size. Simply find a common hole saw that matches the hole or radius that you are working with and insert the proper arbor (included). Slide in the hardened punch and tap with a hammer just like a typical transfer punch. Perfect for duplicating sheet metal panels.
The threaded arbors are Zirconium Nitride coated to make sure they never wear out. The kit comes with a 3D printed tool holder with magnetic base to keep organized and close at hand.
