  • Large Circle Compass Feature: A combination of the MK3's new aluminium Compass Hub and Guide Rods. Extends the CRB7's circle cutting range from 19'' to over 4ft/50” Dia. (225 – 1270mm). The circle diameter can also be micro adjusted without having to remove the router or assembly from its set-up.
  • Two pairs of Guide Rods: 9/32'' (7mm) diameter to fit routers with smaller rod drillings E.g. Porter Cable's 690 series and 5/16” (8mm) diameter to fit routers with larger rod drillings E.g. DeWalt 621.
  • Guide Rod Locking Bars: Improve the efficiency of the initial ‘‘set up” and reduce time taken when assembling the rods. Insert the Lock Bars into the Guide Rod drillings to tighten or loosen the assembly.

Tool Functions:

  • Adjustable Dadoing - with a clamp guide - Set the clamp guide once and adjust the position of the router via the CRB7's Micro Adjuster. CRB7 increases router-to-clamp guide surface contact area and reduces clamp guide set up time – eliminating it in some cases.
  • Adjustable Mortising – a unique feature that allows "Centered and Off Centered" mortises plus decide on and precisely control the actual width of the mortise.
  • Anti Tilt Support – Another first, variable height triangulated stabilization – Usually most of the router base remains unsupported when edge routing – CRB7 Anti tilt leg eliminates router tilt especially important when routing work-pieces with a high aspect ratio.
  • Compass - Rout precision circles and holes that are actually smaller than the base of the router - CRB7 can rout circles and wheels from: 3/4 ” – 8 3/4 ” radius (19 - 225mm) that's diameters ranging 1 1/2 ” – 17 1/2 ” to (38 - 450mm) with a ¼” / 6mm straight router cutter.
  • Off Set Base Plate - Increases overall router stability – reducing errors when edge molding by more than doubling the surface contactarea between router and work piece. CRB7 also moves the pivot hand guiding the router toward the center of the panel, smoothing out the router pass action, reducing the chance of burn marks.
  • Adjustable false panel rebate copier - The CRB7 provides a simple and exceptionally quick way of accurately repeating a molded dado for production batch quality faux or false paneling. Flush Trim Edging Kit - With virtually no set up time - quick fit the Trim Jig riser pad to accurately machine trim hard wood and iron on edging flush with the core board in seconds.
