Application
- Spindle extensions can be used to extend the shanks of sanding and milling tools
- These permit use in hard-to-reach areas
- The extension for drive spindles is clamped into the machine's collet chuck (pneumatic or electric drive) or in the handpiece of the flexible shaft
- Spindle extensions are an economical alternative to custom burs and mounted points with a long shank

Notes
Note: The valid safety and accident prevention regulations must be observed when using spindle extensions.
When working with long shanks, the tool must be inserted into the workpiece (e.g. bores, pipes, ducts or grooves) before switching on the drive machine. The extension must never be allowed to run freely in the tool outside the workpiece.
Failure to observe this instruction results in a higher risk of accidents! Under unfavourable conditions, the extension with the clamped tool may snap off. The extension is only intended for manual use in conjunction with suitable pneumatic or electric drives or flexible shaft handpieces for tools with standard shanks. It is clamped into the true-running collet chuck of the devices in conjunction with a tool that is duly approved for the rotation speed. It should never be clamped on the transition radius.
Clamping of a second extension or tools with over-long shanks is prohibited.
