Big and Small Router Center Bits

Achieve flawless precision in your woodworking projects with the professional Router Subbase Centering Pin and Cone Set. Often referred to by craftsmen as “big and small” router center bits, this essential calibration kit is the secret to perfectly aligned template routing, hinge mortising, and inlay work. Driven by a heavy-duty dual-ended steel pin design, it temporarily locks your router’s subbase plate or brass template guides into a dead-center alignment with your router spindle, entirely eliminating manual measurement errors.

Even a fraction of a millimeter of misalignment on your router base plate can cause template guide bushings to ride unevenly, ruining hours of precision work or causing your router bit to dangerously strike the brass collar. This universal kit features a solid steel pin with a 1/4-inch end on one side and a 1/2-inch end on the other, allowing it to fit effortlessly into any standard router collet. Accompanied by a durable, smooth-sliding centering cone, this tool physically forces your base plate into perfect concentricity while you tighten the mounting screws. It is an indispensable, budget-friendly insurance policy for your expensive hardwood stock and router bits.

Router Centering Kit Performance Highlights:

• Dual-Ended Pin Versatility: One solid steel pin accommodates both standard 1/4-inch and 1/2-inch collets—simply flip the pin to match your router’s collet size.

• Automatic Wedge-Lock Centering: The sliding alignment cone acts as a mechanical wedge, centering subbase plate openings and guide bushings up to 1-3/4 inches without tedious measuring.

• Protects Cutting Equipment: By ensuring perfect concentricity, it prevents spinning carbide router bits from coming into contact with and damaging metal template guide bushings.

• Universal Router Brand Fitment: Engineered to work seamlessly with all major router brands, including Bosch, DeWalt, Makita, Trend, Milwaukee, Ryobi, and Porter-Cable.
