Synchronizer tap holder minimizes thrust load exerted on the tap and workpiece during the forward-reverse window in rigid tapping operation, resulting in an extended tap life by 50% or more when comparing the same tapping operation with a floating tap holder, and also provides better surface finished threaded holes
Taper ground to AT3 or better specification ensures 80% or more contact with spindle to reduce harmonics and improve runout tolerance
Inside bore are precision turned to engage a better contact with retention knob's pilot to increase rigidity
Precision turning surface finish provide perpendicular contact with the flange of retention knob to increase rigidity

1/8" or #6 to 1/2" Tap or M3 to M10 Tap
To achieve AT3 or better taper contact as an industry standard, our taper surface are precision ground on Shigiya CNC grinder from Japan. We are not satisfied with just meeting the industry standard, the surface roughness on the taper is maintained to mirror finish.
The maximum torque is laser marked on the ER collet nut face to take the guess game out of the way to ensure proper amount of force should be applied while tightening. Innovative coating process significantly increases the clamping force by 75% compared to standard ER collet nut. More gripping force provides better rigidity and reduces the possibility of losing grip on the round shank which lead to expensive damage on cutting tools and work piece material.
Although the tool holder is compatible with standard ER collet, it's recommended to use ER Rigid Tap collet which has a square design slot in the rear end of the collet to lock in on the flat-sided shank, preventing the tap from spinning inside. On Tegara ER rigid tap collet, the bore size and square size are laser marked on the collet body for easy identifying tap size.
For best result it's preferably to use Synchronizer in a thru hole application more than a blind hole and follow the recommended tap size range. For tapping in a blind hole, it's recommended to leave 0.078" / 2mm depth of material at the bottom of the blind hole to accommodate the tension compression range of 0.019".
