Product Description
The CMT 855.801.11 Window Sash Set by CMT is a precision router bit set engineered for crafting custom window sashes and door profiles with clean, repeatable results. Designed to produce a 12.7mm (1/2 in.) profile, this set gives woodworkers the tools to create window sash joinery that is both structurally sound and visually refined. Whether working on replacement windows, custom millwork, or decorative door frames, this carbide-tipped router bit set delivers consistent cuts across hardwood and softwood applications.
Key Features
- Window Sash Profile Set - purpose-built design: Engineered specifically for window sash routing, this set produces a precise 12.7mm profile, making it the right tool for custom door and window millwork without requiring multiple separate bits.
- 1 1/2 in. cutting diameter with variable cutting height (11/16 in. - 1 3/8 in.): The adjustable cutting height range accommodates different workpiece thicknesses, giving you flexibility across a variety of sash and frame dimensions in a single setup.
- 1/2 in. shank - increased stability and reduced vibration: A full 1/2 in. shank provides a secure, rigid connection in both handheld routers and router tables, minimizing chatter for smoother profiles and improved surface finish.
- 2-tooth HW (carbide-tipped) construction - extended cutting life: Hardwood-grade carbide tips hold a sharp edge longer than standard steel, reducing the frequency of bit changes and maintaining cut quality across extended use on hardwoods and softwoods alike.
- Right-hand rotation (RH) - standard compatibility: Operates with the standard right-hand rotation of conventional routers and router tables, ensuring straightforward setup without any special configuration.
- Total length range of 2-3/16 in. - 3-5/16 in. - adaptable reach: The variable total length allows the bit set to be configured for different depth and profile combinations, adding versatility to your window sash and door making workflow.
Why This Product
- If you need to mill accurate window sash profiles without sourcing multiple individual bits, this dedicated set provides everything required to cut and match the 12.7mm sash profile in one coordinated package.
- The 1/2 in. shank size is the preferred choice for router table work and heavy-duty routing because it reduces deflection and vibration - critical when routing precise joinery profiles in hardwoods.
- With a cutting height that spans 11/16 in. to 1 3/8 in., this set handles a practical range of sash thicknesses, reducing the need to swap bits when working with varying stock dimensions.
- Carbide-tipped (HW material) construction means the cutting edges resist wear during extended production runs, making this set a durable investment for shops regularly producing custom windows and doors.

Frequently Asked Questions
What profile size does this window sash set produce?
This set is designed to create a 12.7mm (1/2 in.) window sash profile, suitable for custom doors and window frames requiring precise, repeatable millwork.
Can this bit set be used in both a handheld router and a router table?
Yes. The 1/2 in. shank and right-hand rotation make this set compatible with standard handheld routers and router tables. Router table use is particularly recommended for the control and consistency it provides when routing window sash profiles.
What is the cutting height range for this set?
The cutting height ranges from 11/16 in. to 1 3/8 in., allowing the set to accommodate different stock thicknesses within a single setup.
What type of cutting tip material is used on this bit set?
The bits in this set use HW (hardwood-grade carbide-tipped) cutting edges, which provide durability and longer cutting life compared to standard high-speed steel, particularly when routing hardwoods and other dense materials used in window and door production.
