Types of Pipe Beveling Tools

WART Sanitary Pipe and Tube for Welding

ID Clamping Pipe Beveling Tools
MILLHOG® Series

ID clamping bevelers mount inside the pipe and self-center. They are ideal when you can access the pipe I.D. and want maximum stability.

Typical Uses
  • Boiler tube replacement
  • Power plant piping
  • Process piping and manifolds
  • Heat exchanger work
Key Benefits
  • Rigid ID clamping for chatter-free bevels
  • Precise centering for square, repeatable preps
  • Wide range of tools to cover 0.5 in I.D. up to large pipe sizes

COHOG Split Frame Machine Cutting and Beveling Tool

OD Clamping Tools & Split Frames
COHOG Series

OD clamping tools mount on the outside diameter of the pipe. They are the right choice when you cannot access the pipe I.D. or when the pipe is lined. Split-frame machines can cut and bevel in one setup.

Use OD Tools When
  • The I.D. is lined or coated
  • There are obstructions inside the pipe
  • You are working on large diameter pipelines in place
Typical Uses
  • Pipeline tie-ins and repairs
  • Refineries and petrochemical plants
  • Heavy process lines and large headers

Selection Guide

How to Choose the Right
Pipe Beveling Tool

01

Define Your Pipe & Weld Prep

Start with clear pipe data so you can match the right tool to the job.

  • Pipe size range (I.D. and O.D.)
  • Wall thickness and schedule
  • Material: carbon steel, stainless, duplex, super duplex, high chrome
  • Weld prep: bevel only, bevel + face, bevel + bore, compound bevel
02

Match Material & Application

Choose how the tool will mount and what size band it must cover.

  • ID clamping bevelers for most process pipe, boiler tubes, and heat exchanger work
  • OD clamping tools and split-frame machines when you cannot access the I.D.
  • Confirm each tool’s minimum and maximum pipe sizes to match your project range
03

Select Drive, Cutters & Accessories

Match the drive type and tooling to your worksite and materials.

Drive Options
  • Pneumatic for most field work
  • Electric where air is limited
  • Hydraulic for heavy-duty cutting and large diameter pipe
Cutters & Accessories
  • Blades matched to material and bevel geometry
  • Correct mandrels, clamps, and rounding pads for your size range
04

Decide Whether to Rent or Own

Choose how you want to deploy the equipment.

Purchase
  • Best for ongoing maintenance and construction work
  • Standardize pipe beveling across plants and crews
Rent
  • Ideal for outages, shutdowns, and one-time projects
  • Try a specific tool before adding it to your fleet

Common Questions

Frequently Asked Questions

A pipe beveling tool is a machine that cuts an angled edge on the end of a pipe before welding. It produces consistent bevels that help welders achieve proper penetration and reduce defects.

Pipe beveling shapes the weld joint so the welder can access the root of the joint and control penetration. Good bevels reduce lack-of-fusion defects, improve weld quality, and help avoid costly rework and delays.

Common types include ID clamping bevelers, OD clamping bevelers, split-frame cutting and beveling machines, and high-speed bevelers for thin-wall tube. Each type is designed for a specific range of sizes, materials, and working conditions.

Choose an ID clamping beveler when you have good access to the inside of the pipe and need quick bevels with precise centering. These tools are ideal for most process piping, boiler tubes, fabrication facilities, and heat exchanger applications where you need stable, chatter-free bevels.

OD clamping and split-frame tools are better when you cannot access the pipe I.D., when the pipe is lined or coated, or when the pipe must stay in place. They are often used for pipelines, refineries, and large process lines where cutting and beveling in one setup saves time.

ESCO pipe beveling tools cover a wide range from 0.5″ I.D. to 36″ O.D., from small tube sizes up through large diameter pipe. The exact ranges depend on the model, and together the product family covers common boiler tube, process pipe, and pipeline sizes.

Yes. Many ESCO tools are designed to handle stainless steel, duplex and super duplex, and other highly alloyed pipe materials. With the correct cutters and settings, they pull a thick chip and produce clean bevels without damaging the pipe.

Yes. ESCO maintains a rental fleet for customers who need tools for outages, shutdowns, or specific projects. Renting is a good option for short-term work or when you want to try a tool before purchasing.

Most operators can learn to set up and use ESCO beveling tools with a short amount of training and practice. The tools are designed to be simple to operate while still providing accurate, repeatable weld preps.

Basic maintenance includes cleaning the tool, checking clamping components, inspecting bearings and gears, and replacing cutters when they wear. Following the maintenance guidelines helps maintain accuracy and extend tool life in harsh environments.

Yes. Several ESCO tools have narrow bodies and compact gear heads that fit between boiler tubes and other tight areas. Choosing the correct model and mandrel kit lets you bevel in tight working envelopes that grinders and larger machines cannot reach.

Many ESCO tools are designed to pull a thick chip and produce a clean bevel without cutting fluids. For some materials and applications, cutting fluids may still improve tool life and surface finish, and your application specialist can advise you.

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.
