h3. From #4-1/4" (0-80 IN/LBS.) * Very sensitive, calibrated torque control prevents tap breakage when bottom tapping. * Short compression stroke allows holes to be retapped and ensures depth control. * Rugged alloy steel construction for long trouble-free service life. * Free-floating ball bearing tension stroke ensures thread size and quality. * Small outside diameter allows tapping near shoulders without tap extensions. * Short gage length provides more clearance on vertical machines. * Quick-change system allows dull taps to be replaced without removing unit from the spindle. * Radial float improves thread quality and tap life. 2007-01-17T12:17:22+00:00 false false 83 true false From #4-1/4” (0-80 IN/LBS.)
