TECH TIP - Recommended Cutting Speed for Tube Squaring and Severing Equipment

To obtain minimum burr tube ends it is essential that heat buildup be avoided. When either tube or the tool bit gets hot, the tube material starts to flow or push away from the tool edge as a burr, instead of being cut cleanly with a minimum burr.

TECH TIP - Potential For Carbon Contamination from High Speed Steel Tool Bits

The potential for carbon contamination of high purity and ultra-pure stainless steel piping/tubing systems for the use of High Speed Steel (HSS) tool bit has been discussed and debated for many years. In most cases the question comes up on systems using electropolished stainless steel tubing which has to be squared for autogenous welding. There is no acceptable alternative cutting material for achieving a burr-free tube end that does not contain carbon. A stainless steel tool bit that is carbon free does not exist.

Portable Pipe Cutting Equipment for High-Purity Weld Preps

by Bill Atkinson

Portable pipe cutting equipment is playing an ever-increasing role in the construction and maintenance of today's piping systems. As the specifications, materials, and design of these systems have increased in complexity, the need for rapid, accurate, and repeatable on-site cutting performance can be instrumental in reducing costs associated with system creation and management.
