Spindle Extensions

Burs (shank dia. 1/8” and 1/4”) can be extended with spindle extensions, allowing access to hard-to-reach areas. The extension is mounted in the collet chuck of the machine (air-powered or electric), or in the handpiece of the flexible shaft. In some applications spindle extensions are efficient alternatives to customized burs with long shanks.
