Freud 16-500 1/2-Inch Mortising Router Bit is a carbide-tipped mortising bit built for clean, precise hinge mortises, hardware recesses, grooves, and dadoes. This is a mortising router bit designed for cutting clean recesses and straight slots in wood and sheet goods. Model Number: 16-500. With a 1/2 inch cutting diameter, 1/4 inch shank, and 3/4 inch carbide height, it fits the kind of routing work where control and surface quality matter just as much as speed.

What makes this bit useful on real work is the down shear geometry used on most Freud mortising bits. Instead of lifting fibers at the surface, it pushes them down during the cut, which helps reduce splintering on the top face of veneered plywood, melamine, hardwood, and other finish-sensitive materials. If you're cutting hinge pockets in cabinet doors or cleaning out a shallow mortise where the visible face needs to stay clean, that matters.

Freud also builds this bit with deep center gullets for fast chip removal. That is not just a spec sheet talking point. In a mortising application, waste has to get out of the cut quickly or the bit starts packing chips, heating up, and leaving a rougher bottom. The deep gullet design helps keep the cut moving, especially in plywood, composites, and solid wood where chip load can build fast.

The size is practical for a wide range of detail routing jobs. The 1/2 inch diameter is a common sweet spot for hinge and hardware work, while the 3/4 inch carbide height gives enough cutting length for many shallow mortises and slotting tasks without stepping up to a larger bit than the job needs. The 2-7/16 inch overall length keeps it compact enough for good control in portable routers while still giving enough reach for table and CNC setups.

Freud's Perma-SHIELD coating is another jobsite-friendly detail. It helps reduce drag and resists pitch buildup and corrosion, which is especially helpful when you're moving between hardwood, softwood, plywood, and composite materials. Less buildup on the bit means more consistent cutting and less cleanup at the end of the day.

Compatibility is broad and straightforward. The 1/4 inch shank fits routers that accept standard 1/4 inch shank bits, and Freud lists this bit for use in CNC, hand-held, and table-mounted portable routers. That makes it a flexible option for cabinet work in the shop, hinge mortising on site, and repeat slotting operations where a CNC setup saves time.

This bit is best for woodworkers, cabinet installers, trim carpenters, and serious DIY users who want a cleaner top edge than a general straight bit usually delivers. If your work involves visible surfaces, hardware recesses, or clean dadoes in plywood and sheet goods, the Freud 16-500 1/2-Inch Mortising Router Bit is the kind of bit that earns a spot in the case fast.
