Precision hinge mortising bit

The CMT 850.001.11 is a carbide-tipped router bit designed to cut clean hinge mortises in solid wood and sheet goods. Its 3/8 in cutter diameter produces the standard shallow recess required for butt hinges on doors, cabinets and casework. Woodworkers and joiners use it on handheld or table-mounted routers for repeatable, splinter-free results.

Upgrades from straight or spade bits

A dedicated mortise profile eliminates the need to chisel out waste or make multiple passes with a straight cutter. The carbide tips hold an edge far longer than high-speed steel, so the bit stays sharp through many doors. The jump is worth it when you cut mortises regularly and want consistent depth without layout lines for every hinge.

Fits 1/4 in collet routers

The 1/4 in shank fits most compact and mid-size routers, so no collet change is needed on common machines. Carbide construction reduces sharpening downtime and frees up bench time for assembly. The bit works in hardwood, softwood and man-made boards without requiring a specialised jig beyond a simple edge guide or template.

Questions about this item

Will the 1/4 in shank fit my router collet?

The bit has a 1/4 in shank, which matches the standard collet size on most handheld and table-mounted routers.

How do I set the cutting depth so the hinge sits flush?

Adjust the router so the carbide tip cuts a mortise 7/16 in deep; test on scrap first because plunging too deep in one pass is the common error.

When should I replace this bit?

Replace it when the carbide edges no longer leave a clean shoulder on the mortise or when tear-out appears despite sharp feed rate.
