3/16-Inch Upcut
The 0.1875-inch upcut section is the Series 3200 configuration specified for routing 1/4-inch material or producing dado cuts.


A Vortex Tool Series 3200 three-flute solid-carbide mortise compression spiral with a 1/2-inch cutting diameter, 1-inch cutting-edge length, 0.1875-inch upcut length, 1/2-inch shank, and 3-inch overall length. The short 3/16-inch upcut configuration is intended for 1/4-inch material or dado cuts while the compression geometry supports clean finishes on both faces.
This Series 3200 Viper router bit combines upcut and downcut flute sections with a short 3/16-inch upcut. Vortex identifies this configuration for 1/4-inch material or dado cuts, while the three-flute design supports faster feed capability and clean finishes on both sides of compatible material.
Designed for compatible high-speed CNC routers and routing machines using a correctly sized 1/2-inch collet or toolholder. Confirm spindle rotation, tool projection, workpiece thickness, cut depth, RPM, feed, workholding, and chip evacuation before production use.
The Vortex Tool 3287 is part of the Series 3200 three-flute compression-spiral range. Its upcut and downcut flute sections compress the material toward the centre of the cut, helping control chipping and fuzzing along both workpiece faces.
Vortex marks 3287 as the 0.1875-inch mortise-style configuration for 1/4-inch material or dado cuts. The short upcut section helps position the compression transition within thin material, while the three-flute design provides additional cutting-edge engagement for faster feed capability on compatible high-speed routers.
The verified 3287 configuration uses a 1/2-inch cutting-edge diameter, 1-inch cutting-edge length, 1/2-inch shank, 3-inch overall length, 0.1875-inch upcut section, three flutes, compression geometry, and right-hand rotation. Correct collet condition, spindle runout, projection, feed, RPM, workholding, and chip evacuation are essential to finish quality and tool life.
Technical Specifications
The 0.1875-inch upcut section is the Series 3200 configuration specified for routing 1/4-inch material or producing dado cuts.
The three-flute configuration provides additional cutting-edge engagement to support faster feed capability in compatible production routing.
Combined upcut and downcut flute sections compress the cut toward the workpiece centre to support clean top and bottom edges.
Confirm a clean, undamaged 1/2-inch collet or compatible holder, correct right-hand spindle rotation, adequate shank engagement, safe tool projection, machine RPM limits, feed rate, workpiece support, workholding, and chip evacuation before use. Program the cut so the 0.1875-inch upcut section and compression transition are positioned correctly within the workpiece. Final feed and speed values must be established for the machine, material, cut depth, and required finish.
Vortex Tool 3287 combines Series 3200 three-flute mortise compression geometry with a verified 1/2-inch cutting diameter, 1-inch cutting length, 0.1875-inch upcut, 1/2-inch shank, and 3-inch overall length.
The solid-carbide Viper design is intended for compatible high-speed routing applications where 1/4-inch material or dado-cut capability, faster feed potential, and clean finishes on both sides are important production goals.
