Product Information

Full details

The MICROJIG MATCHFIT Relief Router Bit is an essential tool for woodworkers using the MATCHFIT system who want to achieve cleaner, more professional dovetail grooves. By removing 55% of the material before the primary dovetail cut, this bit significantly reduces heat and strain on your primary router bit, extending its life and improving overall cut quality. While this tool dramatically improves results, it is a specialized accessory that must be used in conjunction with a separate MATCHFIT Dovetail Router Bit to complete the groove process.

FAQs

Do I need the standard MATCHFIT Dovetail bit to use this?

Yes, the Relief Router Bit is a preparatory tool and requires the separate MATCHFIT Dovetail Router Bit to finalize the track geometry.

Can I use this on a handheld router?

Yes, this bit is designed to be used with standard handheld routers or router tables that accommodate a 1/4-inch shank.

What is the primary benefit of the roundover profile?

The 1/16-inch roundover profile prevents the top edges of your groove from chipping or tearing out, ensuring a clean and professional look.

How much material does this bit remove?

This bit removes 55% of the waste material, which helps preserve the sharpness and longevity of your secondary dovetail bit.

Is the shank size compatible with all routers?

This bit has a 1/4-inch shank; it is compatible with any router collet that supports 1/4-inch bits.

Troubleshooting

Burning marks on the wood surface

Ensure your router speed is correct and check that you are not moving the router too slowly through the material.

Bit slipping in the collet

Ensure the 1/4-inch shank is not bottomed out in the collet and that the collet is tightened securely.

Rough groove edges

Check that the bit height is set correctly using the laser-etched guide and ensure the router base is flat against the workpiece.

Pros and Cons

Pros

  • Significantly extends the lifespan of your dovetail bits
  • Reduces motor strain on your router by removing material in two stages
  • Eliminates tearout with the built-in roundover profile
  • Laser-etched depth markings ensure consistent results
  • Produces high-quality, professional-grade track finishes

Cons

  • Requires two-step routing process for final groove completion
  • MATCHFIT Dovetail Router Bit must be purchased separately
  • Not intended for single-pass cutting applications

Setup, Compatibility & Care

The bit features a 1/4-inch shank, making it compatible with most standard trim routers and full-sized routers that accept 1/4-inch collets. Always ensure your router speed is set according to the bit's diameter specifications. To maintain the tool, clear any resin or sawdust buildup using a specialized bit cleaner after heavy use. Store the bit in its original packaging or a protective case to keep the carbide edges sharp and free from chips. Always verify that the bit is fully seated in the collet before starting the router.
