An air-powered saw that can be used in any position to produce perfectly square cuts on water wall boiler tube panels made from highly alloyed tube up to 4-½" O.D. is available from ESCO Tool.

The ESCO APS-438 air-powered saw features a proprietary abrasive blade that can rapidly cut all types of boiler tube alloys including stainless steels and Inconel with ±¹⁄₁₆" accuracy and no HAZ (heat affected zone). Capable of cutting in any position, the saw glides effortlessly along the EscoTrack system which attaches simply to boiler tube panels using two weld tabs.

Featuring a 3-hp motor, the ESCO APS-438 air-powered saw has an ergonomic design and mounts on the 5 ft. steel EscoTrack system by a bracket with four grooved steel wheels that takes the weight off of the operator. It uses only 80 CFM 90 psi shop air and has a safety relief valve to prevent running at excessive speeds. Blades come in 10"- and 12"-dia. sizes.
