Vortex Tool Series 6400 Two-Flute Medium Burr with Plunge Point, 3/8 in × 7/8 in
Medium Burr
with Plunge Point
A solid-carbide, two-flute medium-burr cutter engineered for plunge-capable routing in homogeneous fiberglass and composite materials. SKU 6440 combines a 3/8-inch cutting diameter, 7/8-inch cutting length, 3/8-inch shank, 2-1/2-inch overall length, straight fluting, and a medium burr pattern.
Main Product Description
The Vortex Tool 6440 is the 3/8-inch model in the Series 6400 solid-carbide medium-burr family. Its verified geometry combines two straight flutes, a medium burr pattern, and a plunge point for plunge-capable cutting in compatible fiberglass and composite materials.
The cutter has a 3/8-inch cutting-edge diameter, 7/8-inch cutting-edge length, 3/8-inch shank, and 2-1/2-inch overall length. This matched shank and cutting diameter simplify tool selection while the plunge-point design supports entry operations appropriate to the programmed toolpath and workpiece.
Vortex limits this burr-tool family to material made entirely from one compatible fiberglass or composite type. It should not be applied to mixed constructions containing wood, plastic, or aluminum components. Correct collet condition, tool projection, workholding, cutting parameters, chip and dust extraction, and toolpath strategy remain essential.

Product Highlights
Plunge-Point Geometry
The Series 6400 design adds a verified plunge point for programmed entry into compatible fiberglass and composite materials.
Two Straight Flutes
Two straight cutting flutes are combined with Vortex’s medium burr pattern for the official 6440 cutting configuration.
Matched 3/8-Inch Geometry
The 3/8-inch cutting diameter and 3/8-inch shank are paired with a 7/8-inch cutting length and 2-1/2-inch OAL.
Compatibility & Installation Notes
Use a clean, undamaged precision 3/8-inch collet or compatible holder with adequate shank engagement and minimum practical projection. Confirm that the workpiece is a homogeneous fiberglass or compatible composite construction; Vortex states that this family must not be used where wood, plastic, or aluminum components are present. Verify spindle condition, workholding, entry and exit strategy, feed rate, spindle speed, dust and chip extraction, and toolpath direction before production. Use appropriate machine guarding and composite-dust controls, and remove the tool from service if the cutting edges or shank are damaged.
Plunge-Capable Composite Routing
Vortex Tool 6440 combines solid-carbide construction, two straight flutes, a medium burr pattern, and a plunge point in a compact 3/8-inch cutting configuration.
Correct material verification, collet fit, tool projection, workholding, programmed entry, cutting parameters, and effective dust extraction are essential for consistent routing in compatible homogeneous fiberglass and composite materials.
