Selection Guide

How to Select the Right
Tube Beveling Tool

01

Define Your Tube & Weld Prep

Start with tube data to drive tool and cutter selection.

  • Tube O.D. and wall thickness
  • Tube material such as carbon steel, stainless, or alloy
  • Required weld prep: bevel, face, bore, or J-prep
02

Match Material & Application

Access and tube pitch often determine the tool style.

  • Confirm clearance between adjacent tubes
  • Decide if I.D. or O.D. clamping is possible
  • Consider working position: horizontal, vertical, or overhead
03

Select Drive, Cutters & Accessories

The right setup improves productivity and tool life.

  • Pneumatic, electric, or battery drive options
  • Cutters matched to material and bevel geometry
  • Mandrels, rounding pads, and specialty accessories as needed
04

Decide Whether to Rent or Own

Esco supports both rental and purchase options.

  • Rent for outages, shutdowns, and short-term projects
  • Purchase for ongoing maintenance or fabrication work
  • Scale tool quantities based on crew size and schedule

What Are Tube Beveling Tools?

Tube beveling tools are portable machines that cut an angled edge on the end of a tube to prepare it for welding. Unlike hand grinding, they:

  • Self-center for accuracy
  • Produce consistent bevel angles
  • Reduce fit-up time and rework
  • Improve weld penetration and joint quality

Since 1954

Engineering the First Portable Pipe & Tube Beveling Machines

The ESCO Tool Company was founded in 1954 and developed the first portable beveling machines for tube and pipe fabrication. After early success on the Trident Nuclear Submarine project, this equipment rapidly became the most popular way to bevel high pressure tube and pipe on-site.

Although earlier models clamped on the outside diameter, ESCO developed the first narrow body inside diameter clamping machines, starting in the 1970s, to satisfy the needs of the boiler industry. Seeing how high the demand was for portable fabrication tools, the “Mini” and “Wart” were born, starting the most prestigious line of beveling equipment known to the industry: MILLHOG.

ESCO Tool now has a line of over 23 field-proven products that are used all over the world in power generation plants, pulp and paper plants, refineries, fabrication facilities, public work systems, and other metalworking industries.
