Open O-Flute Geometry
Two open O-flute cutting edges provide chip space for free cutting and controlled chip formation in compatible plastics.


Uncoated HW solid-carbide, right-hand low-helix O-flute upcut router bit for both soft and hard plastics. Its 3/8-inch cutting diameter, 1-inch cutting edge, 3/8-inch shank and 3-inch overall length provide a compact Z2 configuration for compatible CNC routing applications.
A two-flute HW solid-carbide plastics-routing tool with open O-flute chip space, low-helix upcut geometry and right-hand rotation.
For compatible CNC routers using precision 3/8-inch collets or approved toolholding. Confirm plastic type, tool projection, workholding, extraction and cutting parameters before use.
The Royce Ayr Low-Helix O-Flute Upcut Router Bit R52-62603 is specified for routing both soft and hard plastics. Its 0.3750-inch cutting diameter, 1.000-inch cutting edge, 0.375-inch shank and 3.000-inch overall length form a compact configuration for compatible CNC-routed components.
The open O-flute design provides chip space for free cutting and good chip formation in compatible plastics. Its low-helix upcut geometry lifts chips toward extraction while applying upward axial force, so secure workholding is essential.
The right-hand Z2 tool is manufactured from HW solid carbide and carries no coating. Correct collet condition, minimum practical projection, runout control, extraction, feed rate, spindle speed, pass depth and chip evacuation are essential for limiting rubbing, heat, melting and chip rewelding.
Technical Specifications
Two open O-flute cutting edges provide chip space for free cutting and controlled chip formation in compatible plastics.
Royce Ayr lists this series for both soft and hard plastics, allowing one geometry to serve several common routed materials.
The 3/8-inch cutting diameter and shank, 1-inch cutting edge and 3-inch overall length provide a balanced plastics-routing configuration.
Confirm SKU R52-62603, the exact 3/8-inch shank, 3-inch overall length, safe clamping length, right-hand spindle rotation, collet condition, tool projection, machine clearance and workholding before installation. Match speed, feed, pass depth and extraction to the actual soft or hard plastic being routed.
The Royce Ayr Low-Helix O-Flute Upcut Router Bit R52-62603 provides an uncoated solid-carbide Z2 solution with a 3/8-inch diameter, 1-inch cutting edge, 3/8-inch shank and 3-inch overall length.
Its open O-flute design and low-helix upcut geometry support free cutting and chip formation in compatible soft and hard plastics when toolholding and parameters are correctly controlled.
