Upcut Chip Evacuation
The right-hand upcut spiral moves chips upward and is designed to support an excellent finish on the bottom face of compatible routed material.


A Klein T344.KD solid-carbide spiral router bit with a 20 mm cutting diameter, 75 mm cutting length, 20 mm shank, 130 mm overall length, three cutting edges, right-hand rotation, semi-finished chip-breaker geometry, and KleinDIA® DLC anti-friction coating for compatible CNC routing applications.
The T344.KD family combines right-hand upcut geometry, a semi-finished chip-breaker execution, polished cutting edges, and KleinDIA® coating for compatible CNC finish-and-roughing work.
For compatible CNC machining centres, CNC routers, and point-to-point machines using a clean 20 mm toolholding system. Confirm right-hand rotation, projection, spindle condition, retaining-ring arrangement, RPM, feed, chip extraction, and workholding before production use.
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®.
Technical Specifications
The right-hand upcut spiral moves chips upward and is designed to support an excellent finish on the bottom face of compatible routed material.
The verified semi-finished chip-breaker execution supports a practical balance between material removal and finish quality in compatible CNC work.
The anti-friction DLC coating is specified to reduce friction, heat, and wear while supporting smoother chip evacuation over the solid-carbide tool.
Confirm the exact T344.201.RKD Item code rather than the family code T344.KD. Use a clean, compatible holder or collet for the 20 mm shank and verify right-hand spindle rotation, safe projection, retaining-ring arrangement, machine RPM limits, feed, cut depth, entry strategy, dust and chip extraction, workholding, and material support. The official family specifies a Seeger retaining-ring seat on diameters from 12 mm through 20 mm.
Klein T344.201.RKD combines a 20 mm cutting diameter, 75 mm cutting length, 20 mm shank, 130 mm overall length, Z3 upcut geometry, semi-finished chip-breaking, and KleinDIA® coating for compatible CNC routing work.
Correct holder fit, spindle condition, projection, right-hand rotation, feed, RPM, extraction, toolpath, and workholding are essential to achieving the intended bottom-face finish and tool performance.
