STANDARD PNEUMATIC REVERSING SCREW DRIVER / NUT DRIVER / TAPING DRIVER mod 263 GOOD WORKING CONDITION. I have used this PNEUMATIC REVERSING TOOL FOR MANY YEARS FOR THREDING HOLES from 2-56 to 6-32 . , it will also do 8-32 size in thin metal or alluminum . I have power taped 2-56 blind holes in stainless steel without braking a tap with the clutch set for low torque . to set the torque a tiny allen screw is removed and the sleave can be adjusted . THIS TOOL IS NOT DESIGNED TO CHAINGE THE TORQUE SETTINGS OFTEN . IT MEASURES 3/4 inch DIAMETER , and 7 inch long , the hose is 6 feet long . ANY 1/4 HEX WILL FIT IN THE END such as a SCREW DRIVER TIP , I had 1/4 inch hex stock fit for differant size taps to make this a nice tapping tool . THE TOOL TIPS ARE NOT INCLUDED . THE INTERNAL CLUTCH MAKES IT NICE TO PREVENT TAP BRAKING . I ALSO HAVE A LARGER ONE TO LIST FOR SALE . watch for more UNUSUAL equipment and VINTAGE ELECTRICAL STUFF ! ! ! Careful shipping and insurance in the 48 states will be $9.00. Overseas shipping will be more. any questions you can contact audion AT roadrunner.com **********************************good_luck********************************
