View Product Description

This precision-balanced extension works in any 1/2" router collet, extending the cutter height by approximately 30mm. The extension allows the installation or removal of router cutters quickly from above your router table without the need for cumbersome wrenches or locking of the spindle that many routers usually require.

The patented noose grip design gives a full 360-degree hold on the cutter shaft and loosens with a partial turn using the included 5/32, ball-end, hex key wrench. The chuck design means there is no cam to wear out or damage your cutters.

The Musclechuck Universal Extension opening is for 1/2" shank cutters as standard but can be used with collet reduction sleeves for various shank sizes.


  • Change router bits quickly from above the table
  • Extending the cutter height by 30mm
  • 25mm depth within the collet
  • Single tool changes, no need to lock your spindle
  • Run 1/8", 1/4", 6mm, 8mm and 10mm shanked cutters with reductions sleeves

Supplied with a free T-Handle Ball-Hex Key 5/32” textured handle for extra comfort, slip resistance and safety.

Please Note: Style and make of the Ball End Hex Wrench may vary as stock allows.
