Construct Authentic Divided Lite Windows: Freud 99-050 Window Sash Rail End Bit

Build high-quality, authentic wooden windows with the Freud 99-050 Window Sash Rail End Router Bit. This specialized "coping" cutter is the essential first half of Freud's window sash system, designed to cope the ends of rails, sash bars, and muntins to fit perfectly against the profile cuts. When paired with the matching profile bit (Freud 99-051), this tool allows you to construct strong, functional divided lite sashes with ease. It is engineered to handle stock up to 1-3/8 inches thick, making it versatile for various custom window projects.

Precision and durability are built into every cut with Freud's industry-leading TiCo™ Hi-Density Carbide, which stays sharper longer in hardwoods, softwoods, and composites. The bit features the signature Perma-SHIELD® Non-Stick Coating to prevent rust, reduce friction, and resist pitch buildup for a cleaner, burn-free finish. Designed strictly for use in table-mounted routers with a fence, this bit ensures the stability and accuracy required for intricate window joinery.

Pro-Tip: When working with narrow stock for sash bars and muntins, safety is paramount. Always use a dedicated coping sled to securely hold the workpiece as you guide it past the cutter. This not only keeps your fingers safe but also ensures the cut is perfectly square and prevents the delicate ends from blowing out.
