Vortex Tool Series 3400XP Xtreme Performance Two-Flute Mortise Compression Spiral Router Bit with Chipbreakers, 3/8 in × 7/8 in
Two-Flute Xtreme Performance
Compression Spiral
A solid-carbide Vortex Tool Series 3400XP two-flute Xtreme Performance mortise compression spiral router bit with chipbreakers for solid-wood and plywood routing. The verified 3485XP configuration combines a 3/8-inch cutting diameter, 7/8-inch cutting-edge length, 3/8-inch shank, 3-inch overall length, and 0.250-inch upcut section.
Main Product Description
The Vortex Tool 3485XP is a Series 3400XP two-flute Xtreme Performance mortise compression spiral router bit with chipbreakers. Its compression geometry combines a short upcut section with the opposing downcut flute area to support edge control in mortise cuts, thin materials, and correctly positioned through cuts.
Vortex states that its XP geometry is specifically designed to provide as much as three to five times more tool life than standard compression geometry. The manufacturer also identifies the chipbreaker design for free-cutting action in solid wood and plywood materials.
The verified 3485XP dimensions are a 3/8-inch cutting-edge diameter, 7/8-inch cutting-edge length, 3/8-inch shank diameter, 3-inch overall length, and 0.250-inch upcut section. Vortex marks this SKU with the mortise designation and specifies that its chipbreakers are ground in the downcut flutes only.

Product Highlights
Xtreme Performance Geometry
Vortex states that the XP design is intended to provide as much as three to five times more tool life than standard compression geometry.
Mortise-Length Upcut Section
The 0.250-inch upcut section is specified for mortise cuts or thin materials, with chipbreakers ground in the downcut flutes only.
Verified 3/8-Inch Configuration
A 3/8-inch diameter, 7/8-inch cutting length, 3/8-inch shank, 3-inch overall length, and 0.250-inch upcut section define the exact 3485XP format.
Compatibility & Installation Notes
Use a clean, undamaged precision 3/8-inch collet or compatible holder with adequate shank engagement and safe tool projection. Confirm standard right-hand spindle rotation. Position the 0.250-inch upcut section so the mortise compression transition remains correctly located in the workpiece; incorrect depth can prevent the opposing flute sections from producing the intended edge control. Verify material thickness, programmed depth, entry strategy, workholding, spindle condition, feed rate, spindle speed, chip evacuation, and machine clearance before production.
Xtreme Performance Compression
Vortex Tool 3485XP combines solid-carbide construction, two-flute Xtreme Performance mortise compression geometry, chipbreakers in the downcut flutes, and a 0.250-inch upcut section in a 3/8-inch-diameter configuration.
The short upcut section is intended for mortise cuts or thin materials. Correct collet fit, transition depth, tool projection, cutting parameters, workholding, and chip evacuation remain essential to the result.
