Unlock Guide Bush Compatibility for Your Router
Want to use guide bushes with a router that was never designed to take them? The Carbatec Base Plate Adaptor solves that problem for you. Guide bushes give you a smarter alternative to bearing-guided router bits, where small bearings can seize and damage your workpiece, and the bearing position limits the cut height you can achieve. With a guide bush, the cutter moves up and down completely independent of the bush, so you stay in control of your depth while the bush runs cleanly against your template or jig.
This 165mm diameter adaptor plate is machined just 9mm thick, with a rebated 30mm hole that seats the guide bush so it protrudes only below the base of your router, exactly where it needs to be to follow the template. Best of all, it accepts the widely available 30mm threaded bushes used with Carbatec, Leigh, CMT, and many other specialty jigs, giving you a versatile, affordable way to expand what your router can do.
Key Features
- Guide Bush Advantage: Lets you swap unreliable, seize-prone router bit bearings for a fixed guide bush, protecting your workpiece and giving you full control over cut depth.
- Rebated 30mm Hole: Seats the guide bush so it protrudes only below the router base, ready to run smoothly against your template.
- Broad Jig Compatibility: Accepts the widely available 30mm threaded bushes used with Carbatec, Leigh, CMT, and many other specialty jigs.
- 165mm Diameter Plate: A generous base plate footprint for stable, reliable contact across your jigs and templates.
- Slim 9mm Profile: Keeps the adaptor low and unobtrusive so you retain maximum cutting depth from your router.
- Expands Router Versatility: An affordable way to add guide bush capability to routers that lack it or offer only a limited range of bushings.
Main Applications
- Fitting 30mm threaded guide bushes to routers that were never designed to accept them.
- Running your router against commercial jigs such as dovetail and joinery templates.
