Complete Three-Bit System
Matched rail, stile, and slot cutters cover the three verified profile functions in one set.


CMT 855.803.11 is the exact three-piece glass-panel-door set with matched ogee rail and stile cutters plus a dedicated slot cutter. All three components use 1/2-inch (12.7 mm) shanks and verified carbide-tipped cutting geometry.
A matched carbide-tipped system for producing ogee rail-and-stile profiles, an internal square rabbet, and the dedicated retainer slot used in compatible glass-panel door construction.
Specified for compatible professional router-table equipment accepting 1/2-inch (12.7 mm) shanks. CMT and distributor documentation identify this set as router-table-only and not for handheld routing.
CMT 855.803.11 is the exact 1/2-inch-shank variant in the official 8/955.803 three-piece glass-panel-bit family. The set contains matched ogee rail and stile cutters together with a dedicated slot cutter.
The rail-and-stile cutters are identified with a 1-5/8-inch (41.28 mm) diameter, 13/16-inch (20.64 mm) cutting length, and 3-1/32-inch (76.99 mm) overall length. The slot cutter is identified with a 2-1/8-inch (53.98 mm) diameter and produces the 1/8-inch (3.18 mm) retainer-slot format.
The matched profiles leave a square internal rabbet for the glass panel while the slot accepts CMT’s compatible rubber panel-retainer strip. The retainer strip is sold separately and is not represented as included with SKU 855.803.11.
