DynaPrep MDSF 814 Split Frame Remote Controlled 480v Electric Kit The DynaPrep MDSF Split Frame 814 8in-14in OD (DN200 - 350) Remote Controlled 480v 3-Phase Electric Kit, is based on a rotating split ring style OD mounted machine tool (aka clamshells), designed to cut, bevel, single point and counterbore pipe. This kit is complete with a DynaPrep MDSF 814 rotating ring set, 1 extended parting tool slide, 1 extended beveling tool slide, no-time starwheel feed, 480v 3-Phase EPD Electric Power Drive, operating hand tools, manual and storage case. Wachs DynaPrep MDSF modular design split frames are named for their ability to split in half for mounting to the outside of inline pipe. It maintains the low clearance design of our previous LCSF series, but builds on that legacy with dozens of innovations and features to make it more powerful, more versatile and faster to setup and operate. It redefines the standard in portable, cold cutting machine tools.
