All Models

Warranty: G

Features/Benefits

* Used to repair worn bores

* lowers customer machine operating costs and increases service shop revenue

* Used with 1U-9600 Welding Group

* Easy to set-up and operate

* One set-up for machining and welding (increases efficiency and produces more reworked holes per hour)

* Mounting hardware allows machining of hole before welding (helps eliminate impurities in weld)

* Two in-line bores can be welded and machined simultaneously (maximizes production by machining one bore while welding the other)

Portable Boring Bar Unit (110 and 220 Volts)

* Designed as light-duty boring machine

* Suited for field applications, small shops, and light machining

Hydraulic Boring Bar Unit

* Used to machine bores on dozer frames, loader lift arms, center hitches, scraper hitches, and many other locations

* Also used to counter bore and spot face

Boring Bar Power Units

* Exclusive load sensing hydraulic feed

* Remote pendant control

* Specially designed six-finger centering cones provide quick, accurate bar centering, even on badly worn bores

* Adjustable aluminum support bearings will rigidly support bar, feed/drive unit, and Bore Welder

* Prehardened to Rc65 and broached on 101.6 mm (4.00 in) centers for tool holders
