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.

The Musclechuck range fits a wide variety of plunge and fixed base routers. Click here to view the Musclechuck Compatibility Chart.

Features

  • 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 1/4", 6mm, 8mm and 10mm diameter 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.

Don't do reviews, but...........

Staggeringly good service, the shipment arrived from Canada at the Wood Workers Workshop warehouse on the Tuesday, went out by post on Wednesday and arrived with my brother in West Wales on Friday morning ! He's really pleased with it, excellent quality at a reasonable price, flip-out stabilizing tab very useful.

Fantastic all round service!

I've never used Wood Workers Workshop before but have been aware of them for a few years. After spending a long time researching router tables I took the plunge and ordered an Incra top, LS Positioner and router lift, complete with the larger AUKTools router motor. Everything arrived the next day and was packaged superbly. The products are really well made and the router is very powerful and quiet compared to my old one. I had one minor issue with the LS Positioner (an Incra issue, not WWW) and it was resolved very quickly at no cost to me. I would highly recommend this company and the quality products that they stock. There is nowhere else selling woodworking equipment of this quality in the UK. I will be back for more! :-)

AUKTools Dust Extraction Control Dual Port Kit
Best customer service

This company has the best customer service I can remember receiving. I emailed a query tangentially related to the product and got a comprehensive reply by return. I ordered the product on.a Friday and it was delivered on Saturday. The Incra products are of course excellent quality. Only a shame they use imperial fasteners, but I did find I could run am M6 tap through the 1/4 X 20 hole in the sliding washer with no obvious I'll effect so I could fit a Bristol knob to the sliding extension adjustment.
