CMT Mortising Router Bit 3/4" Dia x 3/4" Cut, 1/4" Shank
HW Z2
Mortising Router Bit
CMT 801.190.11 is the exact 3/4-inch cutting-diameter variant in the Series 7/8/901 mortising family. It combines a 3/4-inch cutting length, 2-1/8-inch overall length, 1/4-inch shank, two HW carbide cutting edges, negative shear geometry, and right-hand rotation for hinge mortising, recess work, and jig-guided routing in natural wood and wood composites.
Main Product Description
CMT 801.190.11 is the exact imperial variant in the official 7/8/901 Mortising Router Bits family. The North American row specifies D = 3/4 inch, I = 3/4 inch, L = 2-1/8 inches, S = 1/4 inch, Z = 2, MAT = HW, and RH rotation.
The worldwide metric table confirms the same item as a 19.05 mm cutting diameter, 20.05 mm cutting length, 54 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.
The geometry is suitable for mortising natural wood and wood composites and is compatible with common mortising-jig workflows. This exact Item Code does not carry the B suffix; no bearing or bearing-service component is published in its exact variation row, so the separate top-bearing 801.190.11B configuration must not be substituted.
Best Fit Applications
Product Highlights
Full 3/4-Inch Cutting Diameter
The verified 3/4-inch diameter and 3/4-inch cutting length support larger hinge mortises and controlled recess work.
Negative Shear Geometry
Thick HW carbide tips and negative shear-angle design help control surface fibres for cleaner edges and smoother mortise bottoms.
Exact Non-B Configuration
Item Code 801.190.11 is the standard mortising version and remains separate from the top-bearing 801.190.11B variant.
Compatibility & Installation Notes
Use CMT 801.190.11 only in a compatible router with a sound 1/4-inch collet. Confirm the exact non-B Item Code before installation; bearing, stop-collar, or top-guided service parts associated with 801.190.11B do not automatically apply. Keep the mortising jig, template, and workpiece firmly secured; verify cutter clearance before starting; use controlled passes appropriate to the 3/4-inch cutter diameter; feed against cutter rotation; and follow the router and tool manufacturers' speed, projection, guarding, and workholding limits.
3/4-Inch HW Mortising for Clean Recess and Hinge Work
CMT 801.190.11 combines a 3/4-inch cutting diameter, 3/4-inch cutting length, 1/4-inch shank, Z2 HW carbide geometry, and right-hand rotation.
Negative shear design, verified metric and imperial dimensions, and exact non-B item identity define its use in controlled mortising and jig-guided routing.
