Klein T344.201.RKD is the exact 20 mm variant in the T344.KD KleinDIA® family of solid-carbide finish/roughing spiral router bits. The official Item row specifies a 20 mm cutting diameter, 75 mm cutting length, 130 mm overall length, 20 mm shank, three cutting edges, and right-hand rotation.

The right-hand upcut spiral carries chips upward and is intended to support an excellent finish on the bottom face of compatible workpieces. Its semi-finished chip-breaker execution bridges finishing and roughing duties for CNC machining centres, CNC routers, and point-to-point machines.

KleinDIA® is a diamond-like-carbon anti-friction coating applied over the solid-carbide tool. The official family data identifies reduced friction, lower heat and wear, improved chip evacuation, and greater wear resistance. Supported workpiece groups include hardwood, softwood, MDF/HDF, chipboard, plywood, laminated and paper-coated panels, plastic-coated materials, and mineral materials such as Corian®.
