Compact 1/8-Inch Cutting Diameter
Supports narrow straight cuts, detailed profiles, light slots, and small recessed features in supported wood and hard-plastic applications.


Compact, right-hand, two-flute straight router bit for general-purpose routing in solid wood and hard plastic. Its 1/8-inch cutting diameter, 1/2-inch cutting edge, 1/4-inch shank, and 2-inch overall length support narrow slots, detail routing, light pocketing, trimming, and small-profile CNC operations.
This small-diameter production tool combines two straight cutting flutes, right-hand rotation, and HW carbide construction for controlled routing in supported solid-wood and hard-plastic applications.
Designed for compatible routers and CNC routers using a precision 1/4-inch (6.35 mm) collet or approved toolholding assembly.
The Royce Ayr 2-Flute Straight Wood & Plastic Router Bit R56-21101 is designed for general-purpose routing where a compact 0.1250-inch cutting diameter is required. Royce Ayr specifies this two-flute straight tool for solid wood and hard plastic, making it suitable for narrow grooves, detail profiles, light slotting, trimming, and shallow pocketing.
Its 0.500-inch cutting edge provides useful reach for controlled small-feature machining, while the straight-flute geometry produces neutral axial cutting action compared with upcut or downcut spirals. The 0.250-inch shank supports common precision 1/4-inch toolholding systems.
The 2.000-inch overall length requires appropriate clearance and controlled tool projection. Before production, verify collet condition, runout, right-hand spindle rotation, spindle speed, feed rate, depth per pass, workholding, material suitability, and chip or dust extraction.
Technical Specifications
Supports narrow straight cuts, detailed profiles, light slots, and small recessed features in supported wood and hard-plastic applications.
Two straight cutting flutes provide predictable sidewall control without the upward or downward axial thrust associated with spiral geometries.
The 1/4-inch shank, right-hand rotation, HW construction, and uncoated finish provide clear setup details for compatible routing systems.
Confirm that the router or CNC spindle toolholder accepts an exact 1/4-inch (6.35 mm) shank and provides sufficient clearance for the 2-inch (50.8 mm) overall length. Inspect the collet and nut, minimize unsupported tool projection, verify right-hand rotation and runout, and establish spindle speed, feed rate, depth per pass, workholding, and extraction according to the material, machine, and approved shop procedures.
The Royce Ayr 2-Flute Straight Wood & Plastic Router Bit R56-21101 provides a compact carbide solution for general-purpose routing in solid wood and hard plastic. Its 1/8-inch diameter, 1/2-inch cutting edge, 1/4-inch shank, and 2-inch overall length support narrow grooves, detail profiles, trimming, and light pocketing.
Balanced two-flute straight cutting action and right-hand rotation help maintain controlled sidewalls and consistent dimensions when the tool is correctly held and operated within suitable machining parameters.
