FLOATING Tap HolderTHE OMNI TOOL HOLDER IS NOT INCLUDED.
The tap holder will fit in all of the tooling bars with a 5/8” bore.
The OmniTurn OTC-16 tap holder has many advantages. The tap holder will fit in all of the tooling bars with a 5/8” bore. The holder is kept from rotating by a pin from the top. It can float back and forth smoothly. A spring keeps the holder back against the tooling bar. If you program the feed of the tap a little lower than the lead, the assembly will pull out a little from the bar. Then when the spindle reverses, the tap just “floats”. For small sensitive taps, this is better than a holder with a clutch that can snap the tap on the reversal. The holder is case hardened. It will last a long time.
The holder uses standard OTC-16 collets. Special tapping collets with a square broach in the back are available on request.
The holder takes no additional space on the tooling bar. It is much smaller than self-releasing holders.
NOTE: If you are tapping to the bottom of a blind hole, or have to tap to a specific depth, then we recommend a self-releasing tap holder. It is much easier to hold a depth with the release of a the clutch.
