Solid Carbide Spiral Tools for Precision CNC and Routing Applications
At Ernest Bennett & Co (Darlington) Ltd, we offer the on-site manufacture and servicing of solid carbide spiral tools, providing high-quality tooling solutions for a wide range of boring, grooving, trimming and routing applications.
Our spiral tools are available in diameters from 4.0 mm to 50 mm and can be manufactured in both standard and non-standard sizes and profiles to suit individual customer requirements.
Designed for use across a broad range of materials, our spiral tooling can be supplied for applications involving:
- Solid wood
- Coated wood-based materials
- Veneered materials
- Uncoated wood-based materials
- Chipboard
- Plywood
- MDF
- HPL
- Corian
- Other composite-type materials
With a choice of finishing, compound and roughing tooth configurations, our spiral tools can be specified to suit different cutting applications and desired finish qualities.

Bespoke Spiral Tooling
Every machining application has different requirements, which is why we offer a bespoke service for non-standard sizes and profiles.
Our on-site manufacturing capability allows us to respond quickly to specialist tooling requirements, with fast delivery available on non-standard tools where required.
We can manufacture spiral tools in a range of configurations, including V-point and ball-end profiles, providing flexibility for customers working with different materials, machinery and cutting applications.
Our team can discuss your individual requirements and help identify the most suitable tool configuration for your application.
Suitable for CNC Machines and Stationary Routers
Our solid carbide spiral tools are suitable for use with both CNC machines and stationary routers, making them a versatile choice for professional woodworking and manufacturing applications.
Whether you require tooling for boring, grooving, trimming, profiling or general routing applications, we can provide a solution designed around the requirements of your machinery and material.
Finishing Tooth Spiral Tools
Our finishing tooth spiral tools feature positive or negative helicoidal cutting edges, allowing the tool configuration to be selected according to the specific application.
Positive helicoidal cutting edges
Positive helicoidal cutting edges provide effective chip removal, making them particularly useful where efficient evacuation of material is important during the cutting process.
Negative helicoidal cutting edges
Negative helicoidal cutting edges can provide improved fixation of the workpiece, particularly where vacuum fixing is being used.
The choice between positive and negative helicoidal cutting geometry can therefore be tailored to the machining application, material and workholding method.
Roughing Tooth Spiral Tools
Our roughing tooth spiral tools are designed to help reduce cutting effort during machining.
Available with both positive and negative helicoidal cutting edges, roughing tooth configurations can be selected to suit the particular requirements of the machine, material and workholding system.
These tools are suitable for applications where efficient material removal is a priority before a finishing operation.

Fast Service
Compound Tooth Spiral Tools
For applications where a high-quality finish is required on both sides of the workpiece, we can supply compound tooth spiral tools.
These tools feature up-cut and down-cut edges, helping to produce an excellent finish quality on both the top and bottom edges of the workpiece.
This configuration can be particularly beneficial when machining materials where edge quality and surface finish are important considerations.
Additional Spiral Tooling
In addition to our standard and bespoke spiral tooling range, we can also supply:
- Lock-set tools
- Ball nose end mills
- Spy hole cutters
- V-point spiral tools
- Ball-end spiral tools
- Bespoke solid carbide tools
Our range can be tailored to suit a variety of machining applications, allowing customers to source specialist tooling from a single experienced supplier.

Precision Tooling for Your Application
Selecting the correct cutting geometry and tooth configuration can have a significant effect on machining performance, material removal, chip evacuation and finished edge quality.
Our specialist team can work with you to understand your application and recommend a suitable spiral tool configuration. Factors such as material type, machining operation, workholding method and desired finish can all be taken into consideration when specifying the tooling.
Where a standard tool is not suitable, our on-site manufacturing and servicing capability enables us to produce specialist tools to meet your individual requirements.
Fast Delivery and Bespoke Service
We understand that specialist tooling requirements can arise at short notice. Our ability to manufacture and service solid carbide spiral tools on site allows us to offer a responsive service, including fast delivery on non-standard sizes and profiles where possible.
From a standard spiral tool through to a completely bespoke profile, we can provide a professional tooling solution designed around your application.
