Main Product Description
The Vortex Tool 1360L is the left-hand version of the 1/2-inch Series 1300 two-flute downcut finishing spiral. Its down-shearing action is intended for operations where a clean top edge is the priority, including dado cuts, groove cuts, and through-cuts where bottom-edge quality is less important.
The downcut spiral directs chips toward the work surface while helping maintain part contact with a properly supported table or pod. In nested routing, the chip-packed toolpath can also help preserve vacuum around the cut when the material and machining setup are suitable.
The verified configuration uses a 1/2-inch cutting-edge diameter, 1-3/4-inch cutting-edge length, 1/2-inch shank, 3-1/2-inch overall length, two finishing flutes, and left-hand rotation. The spindle direction, collet condition, tool projection, workholding, entry method, feed, speed, and chip evacuation must all match the application.

Product Highlights
Downcut Edge Control
Down-shearing geometry prioritizes a clean top edge while directing chips downward through the routed path.
Extended 1-3/4-Inch Cut
The 1/2-inch cutting diameter is paired with a 1-3/4-inch cutting length, 1/2-inch shank, and 3-1/2-inch OAL.
Compatibility & Installation Notes
This is a left-hand rotation tool. Confirm that the spindle, holder, collet, programmed rotation, and toolpath are compatible with the verified left-hand cutting rotation before operation. Use a clean, undamaged precision 1/2-inch collet or holder with adequate shank engagement and minimum practical projection. Verify clearance for the 1-3/4-inch cutting length and 3-1/2-inch overall length, and secure the workpiece against the downward chip load. Do not plunge straight down with this downcut tool; use an appropriate ramp, lead-in, predrilled entry, or other machine-approved entry strategy. Confirm feed, spindle speed, chip evacuation, vacuum support, and cut direction before production.
Left-Hand Downcut Control for Clean Top Edges
Vortex Tool 1360L combines solid-carbide construction, two-flute finishing geometry, downward chip flow, and verified left-hand rotation in a 1/2-inch cutting configuration.
Correct spindle direction, collet fit, tool projection, entry method, workholding, vacuum support, cutting parameters, and chip management are essential for controlled dado, groove, through-cut, and nested-routing operations.
