Point-Cutting Round-Over Geometry
Vortex specifies this solid-carbide profile for decorative trimming and lettering applications.


A Vortex Tool Series 3700 solid-carbide point-cutting round-over bit for decorative trimming and lettering. The verified 3775 configuration combines a 0.125-inch radius, 0.125-inch small diameter, 3/8-inch shank, and 3-inch overall length.
This Series 3700 solid-carbide profile tool uses point-cutting round-over geometry for decorative trimming and lettering. Its verified profile dimensions are a 0.125-inch radius and 0.125-inch small diameter.
Designed for compatible CNC routers and routing systems using a precision 3/8-inch collet or holder. Confirm clearance for the 3-inch overall length and verify profile orientation, toolpath depth, cutting direction, workholding, and material suitability before production.
The Vortex Tool 3775 is a Series 3700 solid-carbide point-cutting round-over bit. Vortex identifies this geometry for decorative trimming and lettering applications.
The point-cutting profile supports controlled decorative edge and lettering work when the programmed path, cutting depth, orientation, and workpiece support are correctly established. Its 0.125-inch radius creates the specified rounded profile without relying on a bearing-guided format.
The exact 3775 configuration has a 0.125-inch small diameter, 3/8-inch shank, and 3-inch overall length. Proper collet condition, shank engagement, spindle runout, tool projection, feed rate, spindle speed, workholding, and chip evacuation remain essential to profile quality and tool service life.
Technical Specifications
Vortex specifies this solid-carbide profile for decorative trimming and lettering applications.
The verified 1/8-inch radius and 0.125-inch small diameter define the exact rounded profile geometry.
A 3/8-inch shank and 3-inch overall length define the exact 3775 machine-interface configuration.
Install the 3/8-inch shank in a clean, undamaged precision collet or compatible holder with adequate engagement and safe tool projection. Verify spindle runout, machine clearance for the 3-inch overall length, profile orientation, programmed cutting direction, toolpath depth, feed rate, spindle speed, workholding, chip evacuation, and workpiece compatibility before production. Vortex does not publish a flute count, rotation designation, or bearing specification for SKU 3775; do not assume those fields from another Series 3700 tool.
Vortex Tool 3775 combines solid-carbide construction with a 0.125-inch round-over radius, 0.125-inch small diameter, 3/8-inch shank, and 3-inch overall length for decorative trimming and lettering.
Accurate toolpath geometry, correct cutting depth, low runout, secure workholding, suitable cutting parameters, and effective chip evacuation are essential to achieving a clean, repeatable profile.
