For compatible routers and mortising jigs accepting a 1/4-inch shank. This exact non-B item is the standard mortising version; it must not be confused with the separately listed 801.128.11B top-bearing variant.
Main Product Description
CMT 801.128.11 is the exact imperial variant in the official 7/8/901 Mortising Router Bits family. The North American row specifies D = 1/2 inch, I = 1/4 inch, L = 1-5/8 inches, S = 1/4 inch, Z = 2, MAT = HW, and RH rotation.
The worldwide metric table confirms the same item as a 12.7 mm cutting diameter, 6.35 mm cutting length, 41 mm overall length, and 6.35 mm shank. CMT equips the family with thick carbide tips and negative shear-angle design for clean hinge mortises with controlled edges and smooth recess bottoms.
This compact 1/4-inch cutting-length configuration is suited to shallow mortises, hinge recesses, and jig-guided routing in natural wood and wood composites. The exact Item Code does not carry the B suffix and should not be represented as the separate top-bearing 801.128.11B flooring-medallion variant.

Product Highlights
Negative Shear Geometry
Thick HW carbide tips and negative shear-angle design help control surface fibres for cleaner edges and smoother recess bottoms.
Exact Non-B Configuration
Item Code 801.128.11 is the standard mortising version and remains separate from the top-bearing 801.128.11B variant.
Compatibility & Installation Notes
Use CMT 801.128.11 only in a compatible router with a sound 1/4-inch collet. Confirm the exact non-B Item Code before installation; bearing, stop-collar, and top-guided service parts published for 801.128.11B do not automatically apply to this version. Keep the mortising jig, template, and workpiece firmly secured; verify cutter clearance before starting; use controlled shallow passes; feed against cutter rotation; and follow the router and tool manufacturers' speed and projection limits.
Compact HW Mortising for Shallow Recesses and Hinge Work
CMT 801.128.11 combines a 1/2-inch cutting diameter, 1/4-inch cutting length, 1/4-inch shank, Z2 HW carbide geometry, and right-hand rotation.
Negative shear design, compact cutting depth, and exact non-bearing item identity define its use in controlled mortising and jig-guided routing.
