Double-Edge O-Flute Geometry
Two cutting edges reduce chip load per edge and create a stronger cross section than a comparable single-edge configuration.


A Vortex Tool Series 5500 solid-carbide double-edge straight O-flute router bit with right-hand rotation, a 1/8-inch cutting-edge diameter, 1/2-inch cutting-edge length, 1/4-inch shank, and 2-inch overall length. Its two cutting edges reduce chip load per edge and create a stronger cutting cross section for compatible plastic-routing applications.
This Series 5500 solid-carbide router bit combines double-edge O-flute geometry with a straight flute and right-hand rotation. Vortex identifies the two-edge design for reduced chip load per cutting edge, a stronger cross section, and effective performance in compatible, slightly harder plastics.
Designed for compatible CNC routers and machining systems using standard right-hand spindle rotation and a clean, correctly sized 1/4-inch collet or toolholder. Confirm tool projection, spindle runout, RPM, feed, cutting depth, workholding, and chip evacuation before production use.
The Vortex Tool 5510 is part of the Series 5500 double-edge O-flute straight range for plastic machining. The verified configuration combines a 1/8-inch cutting diameter, 1/2-inch cutting length, 1/4-inch shank, 2-inch overall length, two cutting edges, a straight flute, and right-hand rotation.
Vortex states that the double-edge O-flute offers the same general cutting characteristics as its single-edge O-flute design while providing two cutting edges that reduce chip load per edge and produce a stronger cross section. The manufacturer notes that this geometry can provide additional tool life in some materials and generally performs better in slightly harder plastics.
The straight-flute configuration avoids an aggressive upward or downward axial chip direction, making chip-clearance strategy, dust extraction, toolpath planning, and material support important parts of the setup. Correct right-hand spindle rotation, collet condition, spindle runout, tool projection, feed rate, RPM, cutting depth, and workholding remain essential to finish quality and tool life.
Technical Specifications
Two cutting edges reduce chip load per edge and create a stronger cross section than a comparable single-edge configuration.
The 1/8-inch cutting diameter is paired with a 1/2-inch cutting length, 1/4-inch shank, and compact 2-inch overall length.
The straight O-flute geometry is supplied in the standard right-hand configuration for compatible CNC routers and programmed toolpaths.
Use this right-hand tool only in a compatible spindle and programmed cutting direction. Install the 1/4-inch shank in a clean, undamaged collet or holder with adequate engagement and safe tool projection. Verify spindle runout, machine RPM limits, feed rate, cutting depth, workholding, chip evacuation, dust extraction, and plastic-material suitability before use.
Vortex Tool 5510 combines solid-carbide construction, double-edge O-flute geometry, a straight flute, and right-hand rotation with a 1/8-inch cutting diameter, 1/2-inch cutting length, 1/4-inch shank, and 2-inch overall length for compatible plastic-routing operations.
Correct spindle direction, collet fit, tool projection, feed, RPM, cutting depth, chip evacuation, dust extraction, and workholding are essential to achieving the intended finish and service life.
