Vortex Tool Series 5800 Double-Edge Upcut O-Flute Router Bit, 1/2 in × 1-1/4 in
Upcut
O-Flute Spiral
A solid-carbide, double-edge O-flute router bit developed for CNC cutting in harder plastics such as acrylic and phenolics. SKU 5853 combines a 1/2-inch cutting diameter, 1-1/4-inch cutting length, 1/2-inch shank, 3-1/2-inch overall length, upcut chip direction, and polished flutes.
Main Product Description
The Vortex Tool 5853 is the 1/2-inch model in the Series 5800 double-edge O-flute upcut family. It is developed for cutting harder plastics, including acrylic and phenolics, at productive CNC feed rates while maintaining a smooth routed finish.
Its polished O-flutes are designed to reduce friction at the cutting edge, help the tool run cooler, and add lubricity without a coating. The upcut spiral directs chips upward, supporting chip removal in properly programmed profiling, pocketing, and slotting operations.
The verified configuration uses a 1/2-inch cutting-edge diameter, 1-1/4-inch cutting-edge length, 1/2-inch shank, and 3-1/2-inch overall length. Correct collet condition, tool projection, workholding, entry strategy, feed, spindle speed, chip evacuation, and material verification remain essential to cut quality and machine operation.
Best Fit Applications
Product Highlights
Double-Edge O-Flute Geometry
Two polished O-flute cutting edges provide the verified Series 5800 geometry for harder-plastic CNC routing.
Upward Chip Removal
The upcut spiral directs chips upward to support evacuation in compatible profiling, pocketing, and slotting toolpaths.
Polished, Uncoated Flutes
The polished flute surface is designed to reduce cutting-edge friction, run cooler, and add lubricity without using a coating.
Compatibility & Installation Notes
Use a clean, undamaged precision 1/2-inch collet or compatible holder with adequate shank engagement and minimum practical projection. Confirm that the plastic grade is suitable for the Series 5800 harder-plastic geometry, and verify machine clearance for the 1-1/4-inch cutting length and 3-1/2-inch overall length. Upcut geometry can lift inadequately secured parts, so confirm workholding, sheet support, entry strategy, feed rate, spindle speed, chip extraction, and toolpath direction before production. Remove the tool from service if its cutting edges or shank are damaged.
Polished O-Flute Cutting for Harder Plastics
Vortex Tool 5853 combines solid-carbide construction, double-edge O-flute geometry, upcut chip direction, and polished uncoated flutes in a 1/2-inch cutting configuration.
Correct material selection, collet fit, tool projection, workholding, programmed entry, cutting parameters, and chip evacuation are essential for smooth CNC routing in compatible acrylic, phenolic, and harder-plastic applications.
