LH 2-Flute Downcut Finisher
This Series 1300 solid-carbide finishing tool uses two helical downcut flutes with left-hand rotation to produce a clean top edge in compatible dado, groove, profile, and through-routing operations while directing chips downward.
Solid CarbideDowncut · LH2 FlutesSKU 1320L
Designed for compatible CNC routers and routing machines configured for left-hand tool rotation and using a clean, correctly sized 1/4-inch collet or toolholder. Confirm left-hand spindle rotation, shank engagement, tool projection, ramped entry, RPM, feed, workholding, and material suitability before production use.
Main Product Description
The Vortex Tool 1320L is the left-hand-rotation variant in the Series 1300 two-flute downcut finishing spiral range. Vortex positions this geometry for operations where the down-shearing effect is preferred and top-edge finish is more important than the bottom edge of the cut.
The downcut spiral directs chip flow downward while helping hold parts against a table or pod. In nested cutting, the routed path can remain packed with chips, which may help preserve vacuum around the workpiece when the toolpath, dust collection, and machine setup are correctly matched.
The verified 1320L configuration uses a 3/16-inch cutting-edge diameter, 5/8-inch cutting-edge length, 1/4-inch shank, 2-inch overall length, and left-hand rotation. Correct collet condition, spindle runout, tool projection, ramped entry, feed rate, RPM, cut depth, chip evacuation, and workholding remain essential to finish quality and tool life.

Product Highlights
Downward Chip Flow
The downcut geometry directs chips and cutting pressure downward, helping hold compatible parts against the table or pod during routing.
Compact Finishing Configuration
The 3/16-inch cutting diameter and 5/8-inch cutting length are paired with a 1/4-inch shank and compact 2-inch overall length.
Compatibility & Installation Notes
Confirm a clean, undamaged 1/4-inch collet or compatible toolholder, correct left-hand spindle rotation, adequate shank engagement, minimum practical tool projection, machine RPM limits, feed rate, cut depth, chip evacuation, workholding, and material support before use. Do not plunge straight down with downcut tooling; use a suitable ramped or pre-drilled entry strategy because straight plunging can cause overheating, fire, or tool breakage.
Clean Top-Edge Downcut Finishing
Vortex Tool 1320L combines left-hand two-flute downcut finishing geometry with a verified 3/16-inch cutting diameter, 5/8-inch cutting length, 1/4-inch shank, and 2-inch overall length for compatible precision CNC routing operations.
Correct collet fit, spindle condition, minimal tool projection, ramped entry, feed, RPM, cut depth, chip management, workholding, and material selection are essential to achieving the intended clean top edge and stable routing performance.
