What The Accu-Tapper Can Do For You!!
If you’re ready to maximize your shop’s profitability, you’re ready for the Accu-Tapper. After all, in a machining setup, the key to increasing profit margins starts with using the most cost-effective equipment. The Accu-Tapper Portable Tapping Machine is designed to eliminate the costly and time consuming tapping and chamfering operations that are done on drill presses and CNC machining centers. Now, both operations can be completed fast and accurately on the Accu-Tapper power tapping machine. With the Accu-Tapper hard at work, your machining center is free to perform more intricate duties such as milling, boring, slotting, etc. It does not get any simpler.. Being efficient equals profitability, and the AccuTaper equals efficiency.

  • The dual clutch design allows it to be very sensitive to pressures applied by the operator, thus eliminating tap breakage.
  • The horizontal design allows it to do long parts and irregularly shaped parts as well.
  • The Accu-Tapper's unique design allows it to tap aluminum and steel without any clutch or lead screw adjustments.
