BMT VS. VDI Tool Holders: What’s The Difference?

Tool holders are essential to any machining process, but it can be difficult to decide which type is right for your machine.

There are two main types of tool holders– BMT and VDI. Each type has its unique benefits and drawbacks.

But don’t worry. We have ten years of machining experience and can help you fully understand.

We offer a comprehensive guide to the differences between BMT and VDI tool holders, so you can decide which type is best for your needs.

BMT Tool Holders

BMT tool holders are specifically designed for mill-turn machines, offering superior rigidity and precision.

The holders offer several unique features for precision tooling.

The four mold mounts provide a secure and rigid hold on the turret head, ensuring accuracy during machining.

Additionally, these tool holders do not require straightening keys, as their straightforward design eliminates the need for additional adjustments.

Installation is quick and easy thanks to alignment keys, allowing for efficient changes during production.

Overall, BMT tool holders provide reliable and precise performance in various machining applications. There are many benefits of using BMT tool holders in CNC machining.

At Toolholdernow, we provide BMT live and BMT static tool holders. The BMT holders include cut-off, facing, OD, and boring holders. If you need to customize it, please contact us.

VDI Tool Holders

VDI tool holders are a versatile and precise choice for turret-style lathes.

Their serrated shaft enables them to be securely inserted into the turret head, where they are held in place by a mating part with teeth.

Additionally, a pin located on the surface of the turret head helps to ensure accuracy in positioning.

These tool holders can be mounted on the outer circumference of the turret or according to its configuration.

Overall, VDI tool holders provide stability and precision during the machining process.

At Toolholdernow, we provide VDI live and VDI static tool holders. The VDI holders include cut-off, boring, radial and axial tool holders. If you need to customize it, please contact us.

BMT VS. VDI tool holders

Difference Between BMT And VDI Tool Holders

While both systems offer flexibility in tool positioning and configurations, some key differences exist.

Here is our summary of the differences between BMT and VDI tool holders.

Mounting Position

One of the biggest differences between BMT and VDI tool holders is their mounting capabilities.

BMT holders are typically mounted on the outside circumference of the turret. In contrast, VDI holders can be mounted on the turret’s outside or face, depending on the machine’s configuration.

Straightness

Another significant difference is that VDI holders require an indication for straightness during installation, while this step is not necessarily needed for BMT holders.

Dial Mechanism

Additionally, most VDI holders have a dial mechanism to assist with installation to prevent rotation out of position.

Our Machining Capabilities
