CMT Stile and Panel Router Bit - 1 3/8" Diameter, 1/2" Shank, 1/8" Radius is a precision-ground carbide-tipped routing tool from CMT, engineered for creating the decorative stepped profiles where raised panels meet stile and rail frames in cabinet doors and furniture panels. Whether you are profiling solid hardwood, working with MDF sheet goods, or combining multiple profiles in a single setup, this 2-flute right-hand rotation bit delivers clean, repeatable results in one pass or in combination with CMT panel bits for more complex profile work.

Key Features

• Hardwood (HW) Carbide Tips - industrial-grade carbide cutting edges hold sharpness longer through dense hardwoods and abrasive MDF, reducing the frequency of resharpening and downtime.
• 1/8" Radius Profile - produces a smooth, consistent rounded shoulder on stile and panel joinery, giving cabinet doors and decorative panels a refined, furniture-quality edge without secondary hand-finishing.
• 2-Flute Design - two cutting edges balance the bit during rotation, producing a smoother surface finish on each pass and reducing tear-out on end grain and veneered composites.
• Right-Hand Rotation - standard RH feed direction is compatible with all conventional handheld routers, router tables, and CNC routing machines, requiring no special toolholder adapters.
• 1/2" Shank Diameter - the full 1/2" shank provides maximum rigidity in the collet, minimizing vibration and bit deflection during profiling cuts on solid wood and MDF panels.
• 3/8" Cutting Height - sufficient cutting engagement depth to fully form the stile and panel stepped profile in a single controlled pass, saving time on multi-step setups.
• 1 7/8" Total Length - a compact overall length keeps the bit stable in the collet while providing enough reach for standard stile and panel profile depths.
• MDF Compatible - specifically cited for use on MDF materials, making this bit a practical choice for painted cabinetry, shop-built doors, and furniture components where MDF panels are specified.

Why This Product

• Designed explicitly for stile and panel work on both solid wood and MDF - one bit handles the decorative profile for traditional raised-panel cabinet doors as well as modern flat-panel MDF door styles, reducing the need to swap between separate tool sets.
• The 1/8" radius and 3/8" cutting height are matched to produce the full stile and panel stepped profile in a single router pass, which speeds up production runs and keeps setups simple on the router table or in a handheld router.
• Compatible with CMT panel bits for building complex, multi-step profiles - giving woodworkers the flexibility to combine this bit with other CMT MDF panel bits when more intricate door or furniture profiles are required.
• The 1/2" shank and 2-flute carbide geometry work together to keep cut quality high and vibration low, which is especially important when routing MDF - a material that can telegraph chatter marks and tear-out more readily than solid wood.
