Expanding device: M10, M14, M19, M24, M29
Drill: 9mm,
Reamer: 10mm,
TCT Cutters: 14mm, 19mm, 24mm, 29mm

Operation
• lf a small proiection of broken fastener is there above the surface then make it a bit smooth and plain using an angle grinder.
• Apply WD-40 or equivalent penetrant spray over the trapped fastener and let it sit for 30 minutes for proper pene-tration.
• Fix the "Weldon shank arbor" provided in this set in the spindle of drilling machine(use suitable taper sleeve if required).
• Clamp the job on the drilling machine in such a way that the TCT cutter selected as per following chart and fixed in the spindle arbor could be positioned at the center of the broken fastener which is to be removed.

• Carry out drilling gradually at slowest speed up to the bottom end of the broken fastener (use sufficient coolant). NOTE: Since TCT cutters start from 12 mm an arrangement for 9 mm Twist drill and 10 mm Reamer is there in this set for making 10mm hole. (Refer above chart)
• Insert the selected TnV Specialized Tool device in the hole as shown in the figure. Rotate counterclockwise for RH fastener and clockwise for LH fastener. The trapped piece of bolt/stud will come out along with the TnV Specialized Tool.
• The core piece which may get blocked inside the TCT cutter can be easily removed from the TCT cutter by pushing it from the other side of the TCT cutter using a pin and hammer.
