FULL DESCRIPTION
A router collet extension is perfect to use when an increased height of router bits is needed on router tables, routing jigs or router bases. This extension gives 50mm of additional height and allows you to easily change router bits above your router table. Simply insert the extension into your 1/2" router, then insert the router bit into the 1/4" or 1/2" ER20 collet and secure it by tightening the collet nut using the supplied spanner.

The extension is supplied with standard 1/4" & 1/2" multi slit ER20 engineering collets which fully grip around the router bit shank for safer routing with less vibration. The collet is made from heat treated precision ground spring steel which gives a runout accuracy of less than 0.01mm. The 1/4" collet has been specifically designed to grip over a 1mm range from 6.5mm down to 5.5mm meaning both 1/4" imperial and 6mm metric shank router bits can be used in the extension. The 1/2" collet has been designed in the same way to grip over a range from 13mm down to 12mm meaning both 1/2" imperial and 12mm metric shank router bits can be used. The extension body has been precision machined from a single piece of high-quality steel which has been computer balanced to minimize vibrations to ensure the extension and therefore router bit will run perfectly true.

The precision machined body alongside the ER20 collets are the ideal combination to give extra height to your router bits while maintaining complete accuracy. The extension has a 1/2" shank and an overall length of 90mm. ©

Superb extension

This extension does what it says on the tin and more. One can clearly tell that it has been manufactured to the highest standards, but most importantly has made life working with my Ruth so much easier in terms of reach and capability
