To identify the carbide insert you need, you’ll need to use the Turning Tool ISO code system. This system provides details on all aspects of the insert, it’s holder and their lengths. If you’ve already got a carbide insert to hand, you can use the Tuning Tool ISO number to order a replacement. If not, then check out our guide on how to identify carbide inserts or give us a call.

Carbide milling inserts are used to provide precision cutting in milling machines. We stock a vast range of carbide milling inserts in different grades and sizes. We have products in stock and ready to ship from leading manufacturers such as Edgetech, Europa and Pramet.

Many companies offer chip breakers on their inserts and these are useful when cutting long stringy materials like stainless steels, non-ferrous aluminum and certain heat-resistant alloys like titanium. Chip breaker styles also relieve tooling pressure at the tip of the insert. However, most chip breaker style inserts come in coated grades and not the ground and polished styles that are utilized in most aluminum applications. So, while they can be manufactured, you may have a hard time finding inventory.

Carbide parting inserts are ideal for parting off, grooving and turning workpieces made of tough materials. We’re confident the ISCAR TAG IC908 Parting Inserts range provides exceptional performance at a competitive price.

Cubic boron nitride (CBN) inserts are increasingly popular among engineers who want precision cutting while working at high temperatures. We have CBN inserts suitable for cutting hardened steel in a broad range of shapes and sizes in-stock and ready to ship.

Top clamp style holders utilize a clamp to securely hold top clamp inserts via a groove on top of the insert. Top clamp inserts use a good amount of carbide and carbide shims, and can sometimes be provided on the insert holder, offering a strong and stable system for threading. One of the main benefits of top clamp style insert is the ability to switch from a grooving insert to a threading insert in the same holder, which can save on tool cost and set-up time. Many of these inserts are double sided, but because of the amount of carbide and grinding involved, these inserts can be costly.

We believe the Right Tool Is Everything™, and we strive to share our experience and expertise in an effort to ensure you select the right tool for your application and follow best practices.

On-edge threading inserts are tangentially mounted on a holder. Normally held by a screw, these provide a smaller footprint for smaller set-ups and additional strength. Many on-edge tooling systems also have a grooving counterpart, so a single holder may be able to handle multiple applications with a single holder. An on-edge style insert can hold a larger thread form that would not fit on a smaller lay down. With the advancement of technology, some of these on-edge inserts also produce more cutting edges than the typical three found on a lay down style. It’s not uncommon to see four or five cutting edges per insert with newer tooling. In certain situations, ergonomics drives the decision of a tool – in some slant bed lathes where the tool is upside down or the tool is at the back of the machine, on-edge style threading tools are used for the ease changing the inserts for the operator. Often, on-edge insert systems are proprietary and more expensive, and many times manufactures will not shim an on-edge insert holder.

R.D. Barrett was established in 1975 by Ron Derek Barrett, an ex employee of both DS & G Lathes and Ford Motor Company. We hold one of the UK largest stock of engineering tooling.

There are many different styles of indexable thread turning tools, but a simple way to classify these tools are: laydown style, 'on-edge' tangentially mounted, and top clamped. Each style has its own benefits. Choosing the right tool requires a look at the benefits each style produces.

At R.D. Barrett, we carry the UK’s largest selection of engineering tools, and through our extensive networks of suppliers, we have access to a huge range of carbide insert and machine tools. If you’re unable to find the size or style of insert that you need online, then give us a call or send us an email. We’re able to source parts from across our range of suppliers, and in many cases, have these delivered to you within days. Spend over £99, and you’ll qualify for free delivery too.

We carry the exceptional ET602 Grade SPMX U-Drill inserts that are engineered for high-performance and optimal thermal resistance. The tough carbide substrate is ideal for demanding drilling applications.

Carbide inserts are indexable pieces of cemented carbide used for machining, face milling, cutting and finishing. They can be used to finish a range of materials, including stainless steel and cast iron. When searching for the correct carbide insert, you’ll need to know its Turning Tool ISO reference. The ISO number provides crucial information on the clamping method, insert shape, holder style and much more. You can learn more about how to identify carbide inserts by reading our in-depth article covering the subject, including the insert grade, insert style, tool holder and more.

If a dedicated threading tool is needed for aluminum, the lay down style threading tool is a cost-effective method to producing threads on aluminum. If applied with a partial profile insert, additional savings can be realized. Other factors such as the thread form, an existing tool holder, or ergonomics may lead you to an on-edge or top clamp style system. Regardless of the system, choose an insert that is uncoated, polished, and hard (wear resistant) to produce the best results in aluminum. Uncoated and polished inserts provide good resistance to BUE (built up edge). Utilize holders with coolant thru capabilities for additional benefits. Producing threads in a machine shop is almost inevitable, but with the right tools and approach, manufacturing threads can be quick and productive. Analyzing your application and available resources can help you quickly choose the best threading tool for the job!

We carry a massive choice of threading inserts, including internal and external threading inserts for precision cutting and machining. We carry a full range of ISCAR threading inserts suitable for general industrial use with a range of materials and machining conditions.

Carbide turning inserts are used to remove material from a workpiece with a leading edge. We sell a selection of carbide turning inserts suitable for precision work, including aerospace applications. You’ll find cutting tools from brands such as Edgetech, Edge Tec, Europa and ISCAR.

Carbide inserts are used to accurately machine metals, including steels, carbon, cast iron, high-temperature alloys and other non-ferrous metals. As well as standard carbide inserts, we all stock CBN inserts and PCB inserts that can be used for precision machining materials such as hardened steel and aluminium alloys.

Lay down style threading inserts are the most common threading system in the world today. The name comes from the insert ‘laying’ down on the holder. These are mostly interchangeable between different companies and have the advantage of selection and abundance in the market. The ability to utilize one holder on multiple style of threads is convenient and economical. The lay down style insert normally comes with 3 cutting edges to index, multiple inserts sizes for different pitches (larger inserts normally produce less TPI, threads per inch) and the inserts use a shim to protect your tool holder, extending not only tool life but also the holder life.
