20mm TCT Undersize Dowel Drill Router Bit – 19.97mm x 1/2" Shank – Quad Tip

20mm TCT Dowel Drill Router Bit – 19.97mm Actual Diameter

Professional TCT tipped dowel drill designed for producing clean, accurate holes and recesses using a handheld router.

The cutter has an actual cutting diameter of 19.97mm, making it nominally a 20mm dowel drill/router cutter. The slight undersize is designed to provide a small amount of clearance to compensate for natural movement and runout when using a handheld router, helping achieve an accurate finished 20mm application.

Unlike conventional 2-tip cutters, this cutter features a 4-tip cutting design. The additional cutting edges distribute the cutting action across four tips, providing efficient material removal and a clean finish.

Manufactured with TCT (Tungsten Carbide Tipped) cutting edges for excellent wear resistance and long service life.

The 1/2" shank provides excellent rigidity and makes the cutter suitable for compatible handheld routers fitted with a 1/2" collet.

Ideal for dowel holes, repetitive boring, recesses, woodworking, joinery, furniture manufacture, cabinet making and general routing applications.
