#theoriginalname In Annular Cutter Technology

Producing annular cutters since 1976, we’ve established ourselves as the world’s leading designer and manufacturer of these incredible metal cutting tools. With M2AL and TCT options, as well as specialist rail cutting equipment, we’ve established ourselves as the premier name in the annular cutter market.

Based in the heart of ‘Steel City’ itself, Sheffield, we design and manufacture cutting tools for heavy-duty performance on a range of different metals. Ideal for use with our Rotabroach magnetic drills, mag drill bits offer a quick, accurate and smooth cut in tough metal surfaces. From rail cutters to twist drills, from powerful annular cutters to convenient hole saws, we’ve got a wide range of different cutting tools.

Designed to provide long-lasting, accurate performance, our mag drill bits range is optimal for hole making in a variety of different applications. Used in sectors including; rail, steel fabrication, bridge building, construction and a number of other industries.

Our M2AL range is ideal for providing fantastic value on a wide range of different materials.

Our TCT range features Tungsten Carbide Tips, for performance on alloys and other tough surfaces.

CUTTING-EDGE TECHNOLOGY

Built to cut through tough metals. this range of superior performance annular cutters has unique tooth geometry that can power through hard surfaces with ease. Created from M2AI for an increased cutting-edge harness, these mag drill bits offer excellent performance against metals with a maximum tensile strength of 900N. 

For users looking for heat resistance, the robustness of Raptor TCT cutters goes the extra distance when put to the test against competitor equipment, even against hardened high-speed tool steel. Their unparalleled drilling ability gives users the power to push through any metal, thanks to super micro-grain carbide tips that can quickly drill through difficult materials. These TCT cutters are also available as a Universal Shank, offering seamless compatibility and lasting power in both weldon shank machines and ‘one touch’ machines – without the need for an adapter. 

Able to withstand the heat both on and off the job, these mag drill bits are a key component in every workshop or site.

ON TRACK WITH ROTABROACH

Our annular cutters have been driving the rail industry since 1999.

Within the railway industry, annular cutters serve a pivotal role, underpinning many of the crucial manufacturing and maintenance processes that ensure the smooth operation of rail transport systems worldwide.

At the heart of rail track manufacturing and installation, annular cutters demonstrate their unmatched capability in crafting precise, smooth, and burr-free holes in rail tracks. This accuracy aids in the secure and aligned assembly of tracks, contributing significantly to the overall safety and efficiency of rail operations.

 

EMPOWERING INDUSTRY

Annular cutters are fundamental tools that are employed across a wide spectrum of industries due to their unparalleled precision and efficiency in creating clean, burr-free holes. Let’s take a look at some key industries where mag drill bits are key:

  1. Construction Industry: In this sector, annular cutters are used to bore holes into a variety of materials such as structural steel, iron, and other metal components. These tools are critical for various applications including the erection of steel frameworks, installation of plumbing and electrical systems, and more.
  2. Automotive Industry: In the production and maintenance of vehicles, annular cutters are used to drill precise holes into various parts, including the engine block, frame, and other metal components. This precision enhances the vehicle’s performance and longevity.
  3. Aerospace Industry: The high standards of precision and safety in the aerospace industry require tools like annular cutters. They are used to cut accurate holes in various aircraft parts, from the fuselage to the internal components, ensuring that these components fit together perfectly.

Everything You Need To Know About Annular Cutters: Answering Common Annular Cutter Questions.

What is an annular cutter?

Annular cutters are a specialist cutter designed for metal cutting purposes, they cut the periphery (or, outline) of the target hole before removing the internal core, often referred to as the ‘slug’.

What are annular cutters used for?

Annular cutters can be found in a number of different industries, essentially any sector which cuts holes in metal regularly can benefit significantly from the use of these tools.

Annular cutters are used regularly in industries such as:

Steel Fabrication
Construction
Oil & Gas Drilling
Rail Maintenance

 

What is a Rotabroach cutter?

With a 40 year heritage going back to the original design of the annular cutter, it’s no surprise that Rotabroach’s name has become synonymous with the annular cutter. With our worldwide reputation for quality and performance, the Rotabroach brand has established itself as the premium option for annular cutters.

What are TCT cutters?

Tungsten Carbide Tipped (TCT) cutters are specially-designed annular cutters which feature tungsten carbide tips, they are capable of cutting through harder metals than HSS (High Speed Steel) cutters.

Ideal for use on tough materials such as: structural and stainless steel, Hardox & Inconel, High Strength Steel and rail track.

How do I choose the right annular cutter?

Annular cutters are fantastic tools, however it’s essential to choose the right one to achieve optimal performance and avoid damage to tools.

Some of the key things to consider when choosing an annular cutter are:

The depth of cut required
The diameter of cut required
The materials being cut

 

How accurate are annular cutters?

Annular cutters are as precise as they are powerful, with an accuracy of approximately +0.004″, -0.000″ in steel, stainless steel and similar materials.
