Custom Cutting Tool Manufacture

When standard tooling isn't the right solution, we design and manufacture cutting tools tailored to your application, material and machining requirements.

Whether you're machining aerospace components, developing a new process or improving an existing operation, we work with you to produce tooling that delivers consistent, repeatable performance.

Every machining challenge is different. Your tooling should be too.

Standard tooling is suitable for many applications, but not all of them.

When tight tolerances, difficult materials or unique component features demand something more, a purpose-designed cutting tool can improve accuracy, reduce machining time and simplify production.

At BJ Associates, we manufacture custom cutting tools designed around your application, helping manufacturers solve machining challenges that off-the-shelf tooling can't always address.

Is a custom tool the right choice?

Many customers come to us after trying multiple standard tools without achieving the results they need.

A custom tool may be worth considering if you're experiencing:

✔ Poor surface finish

✔ Tight tolerances that are difficult to maintain

✔ Multiple machining operations that could be combined

✔ Excessive cycle times

✔ Premature tool wear

✔ Difficult-to-machine materials

✔ Components with unique geometry

✔ An application where standard tooling simply doesn't exist

Sometimes a small change in tool geometry can make a significant difference to machining performance.

Custom Reamers

Designed to achieve precise hole size, finish and concentricity.

Spearpoint Tools

Manufactured for demanding aerospace and precision engineering applications.

Countersinks

Including specialist geometries for aerospace fastener requirements.

Form Tools

Produced to suit complex profiles and repeatable production.

Port Cutters

Manufactured for specialist hydraulic and aerospace applications.

Specialist Tooling

Designed specifically around your component, material and machining process.

Tell Us About Your Project

From Drawing to Finished Tool

Understand the application

Rather than simply manufacturing from a drawing, we begin by understanding what the tool needs to achieve.

Material, machine capability, tolerances, production volumes and machining objectives all influence the final design.

Design the solution

Where required, our team develops tooling geometry to suit the application, ensuring the finished tool is designed around performance rather than compromise.

Manufacture

Using our CNC grinding capability and extensive tooling experience, we manufacture the finished tool to the required specification.

Ongoing support

As production develops, we're available to advise on tooling performance, refurbishment opportunities and future improvements.

The earlier we're involved, the more we can help.

Many tooling challenges are easier, and often less expensive, to solve before production begins.

By involving us during the planning stage, we may be able to recommend changes that:

Reduce machining operations
Improve tool life
Improve chip evacuation
Reduce cycle time
Simplify programming
Improve consistency
Reduce overall tooling costs

Even if your drawing is still being developed, we're happy to discuss potential tooling solutions.

Why B.J. Associates?

Engineering support, not just tool supply.

Practical Experience

FAQ

1. Can you manufacture one-off tools?

Yes. We regularly produce one-off tools as well as repeat production quantities.

2. Can you manufacture from our drawing?

Yes.

Where appropriate, we can also suggest design improvements that may improve machining performance.

3. What industries do you support?

We work with aerospace, precision engineering, defence, motorsport and general manufacturing.

4. Can existing tooling be modified?

In many cases, yes.

We'll assess whether modification or refurbishment is the most suitable option.

5. Do you manufacture carbide tooling?

Yes.

We manufacture a range of HSS and carbide cutting tools depending on the application.

If standard tooling isn't giving you the results you need, let's have a conversation.

Whether you're developing a new component, improving an existing process or looking for a specialist cutting tool, we'd be happy to discuss your application.

Sometimes a short technical conversation is all it takes to identify a better solution.
