The Model 301SP was designed specifically as a tube squarer for autogenous welding applications where microfitting, tube assemblies, or the gripping of short perch length tubing is required with maximum portability. Now, you can do straight tube and fittings with one machine. A design extension of our field proven Model 301, our new “quick collet” provides positive grip with as little as 3/16″ straight length. The Model 301SP’s cutting head accepts the full range of typical 301 style squaring bits. Cleanroom safe, portable or bench mounted, this machine’s variable speed, high torque motor delivers excellent finished on all types of materials and exotic alloys without damaging electropolished surfaces. The unit also features excellent visibility and a micrometer type feed indicator insures precise lengths.

The compact and lightweight Model 301 SP features easy set-up and operation and utilizes a precision OD saddle clamp system which securely holds and rounds the tubing for squaring. Positive clamping of the standard saddles is accomplished with as little as .60″ (15.2mm) of straight tubing and the short perch saddles require .190″ (4.8mm).

Another important feature of the 301 SP is the decreasing rate cam feed which moves the bit forward quickly at the beginning of the feed action and then progressively slower as the tube is engaged, producing up to .200″ overall movement. This provides excellent tactile feedback allowing higher precision and more intuitive operation. No tools are required for the operation cycle, and an air clamping system is available for high production uses. If you like our Model 301, you’ll love our new 301SP!

The Model 301SP (Short Perch) is designed specifically for applications such as working with microfittings where a short gripping length is a consideration.
A variety of Model 301 saddle types are available. Standard saddles provide extra thickness for secure grip, and special Short Perch Saddles provide positive grip with as little as .188″ (5mm) of straight length.
The machine’s variable speed and high torque motor delivers excellent finishes on all types of materials without damaging electropolished surfaces. The unit also features excellent visibility and a micrometer-type feed indicator to produce precise lengths. The Model 301SP offers easy set-up and operation for .125″ (3.2mm) to 1″ (25.4mm) OD tubing up to .125″ (3.2mm) wall, for pipe sizes .250″ to 750″.
The Model 301 features the patented Auto Retract feed system which automatically retracts the bit when the feed handle is released, making it ready for the next cut.
The logarithmic feed cam moves the bit forward quickly at the beginning of the feed action and then slower as the tube is engaged. This provides excellent tactile feedback allowing for higher precision and more intuitive operation.
Most welded high purity tubing systems utilize electro-polished micro-fittings. Our equipment properly prepares micro-fittings for orbital welding by producing perfectly flat, square ends. This is essential for both new and reclaimed components and tube sections. Tri Tool can provide short perch length clamping saddles for use with any specific microfittings you may require.
