Rabbit Tool U.S.A. manufacturers the most advanced chipless cutters and end finishing machines for tube, pipe and bar stock in the world. O.J. Birkestrand invented Rabbit Tool's patented products and has been designing and manufacturing precision, quality machines since 1974. Rabbit Tool has perfected two series of state-of-the-art machines for beveling, squaring, flaring, deburring and chamfering: X+SQ Series portable machines for field use and PC Series machines for high-production, industrial jobs.

Rabbit Tool's X+SQ Series is a designer line of precision end finishing machines for tube, pipe and bar stock. The major difference between models, besides being heavier to accommodate bigger stock, is that the X+SQ50 and 100 have direct drive while the larger X+SQ300, 450 and 600 have a built-in gear reduction ratio and a center line spindle feed mechanism. All models have replaceable parts, including bearings.

X+SQ50 points bars and faces tubes. X+SQ100, 300, 450 and 600 can hold and face extremely short lengths of straight tube or pipe, and they are designed to ID/OD chamfer tube and pipe, as well as chamfer bar stock from 1/8" to 7" diameter.

The heart of the X+SQ Series design is an exclusive, patented over-center dead stop or clam shell die system that prevents stock movement during clamping or unclamping. This allows better cutting control and reduces waste.

Rabbit Tool machines the X+SQ housing as a one-piece aluminum casting structurally designed so that the machines will remain rigid and provide chatterless cuts even under the most extreme loads. 

All the critical internal bores, die dovetails and shoulders are precision machined in one set up on the latest CNC equipment. After machining, the front third of the casting is precision saw cut from the main body. This section forms the lower half of the stock clamping mechanism, which insures accuracy, because all the separated parts are kept as a matched set.
