Straight-Flute Geometry
The verified straight-flute design provides neutral cutting action for general-purpose routing where upcut, downcut, or compression geometry is not required.


Royce Ayr R56-31114 is a 2-flute straight router bit with a 3/8 in diameter, 1-1/4 in cutting edge, 3/8 in shank, and 3 in overall length. Royce Ayr lists it as a general-purpose HW tool for routing solid wood and hard plastic, with RH rotation and no coating.

CNC router / routing-machine applications where the verified 3/8 in shank, RH rotation, cutting edge length, and tool geometry match the setup
The Royce Ayr R56-31114 is a straight-flute routing tool for shops that need a general-purpose cutter for solid wood and hard plastic work. With a 3/8 in cutting diameter, 1-1/4 in cutting edge, 3/8 in shank, and 3 in overall length, it fits routing setups that require a compact 2-flute straight cutter rather than an upcut, downcut, compression, or specialty profile tool.
Royce Ayr identifies this SKU as good for routing solid wood and hard plastic. The straight-flute geometry makes it a practical choice for routing operations where a neutral cutting action is preferred and where the programmed cut depth is within the verified 1-1/4 in cutting edge length.
For production use, the key checks are the 3/8 in shank, RH rotation, 3 in overall length, no coating, and the material being routed. This tool should be matched to the machine spindle, collet/toolholder, RPM, feed speed, cut depth, and guarding requirements before being put into service.
Technical Specifications
The verified straight-flute design provides neutral cutting action for general-purpose routing where upcut, downcut, or compression geometry is not required.
The published configuration combines a 3/8-inch cutting diameter, 1-1/4-inch cutting edge, 3/8-inch shank, and 3-inch overall length.
Royce Ayr lists this SKU for general-purpose routing of solid wood and hard plastic with right-hand rotation and no coating.
Confirm the machine interface before ordering or installing this tool. Check that the router spindle, collet, chuck, or toolholder accepts a 3/8 in shank and that the programmed spindle direction matches RH rotation. Confirm the required cutting depth is within the 1-1/4 in cutting edge length and that the 3 in overall length provides safe clearance for the toolholder, workholding, spoilboard, clamps, guards, and dust collection. Before production cutting, verify the correct RPM, feed speed, pass depth, chip load, and material suitability for the specific machine and job. Royce Ayr lists the tool for solid wood and hard plastic; do not assume suitability for other materials unless confirmed by Royce Ayr, Titan Equipment & Tooling Sales, or the machine/tooling supplier.
