3/4-Inch Mortising Diameter
The exact 801.690.11 row specifies a 3/4-inch (19.05 mm) cutting diameter with a 3/4-inch cutting length.


CMT 801.690.11 is a right-hand T2 mortising bit with a 3/4-inch (19.05 mm) cutting diameter, 3/4-inch cutting length, 1/2-inch shank, and 2-1/4-inch overall length for clean mortising in natural wood and wood composites.
Thick tungsten-carbide tips and a negative-shear design are specified for clean hinge mortising with reduced splintering and rough-bottom defects.
For compatible routers and mortising jigs using a 1/2-inch shank; verify collet fit, right-hand rotation, workholding, depth, clearance, feed, and spindle speed before use.
CMT 801.690.11 belongs to the CMT 801 mortising-bit family for traditional hinge installation and other controlled mortising operations in natural wood and wood composites.
The family uses thick tungsten-carbide tips and negative-shear cutting geometry intended to support clean edges and smooth mortise bottoms when the cutter, jig, router, and workholding are correctly matched.
The exact 801.690.11 configuration uses a 3/4-inch cutting diameter, 3/4-inch cutting length, 1/2-inch shank, and 2-1/4-inch overall length with T2 right-hand geometry.
