Main Product Description
The Vortex Tool 1165 is part of the Series 1100 two-flute downcut roughing spiral range. It is intended for high-feed CNC routing where efficient material removal and controlled top-edge quality are important, particularly in dense hardwoods and plywoods.
Its roughing geometry is designed to make the first stock-removal pass and intentionally produces a rippled edge. A compatible profile or finishing tool can then follow to create the required final surface. The downcut flute direction pushes cutting forces and chip flow downward, helping hold the workpiece against the table and supporting a cleaner top edge in compatible applications.
The verified 1165 configuration uses a 1/2-inch cutting-edge diameter, 2-1/8-inch cutting-edge length, 1/2-inch shank, and 4-inch overall length. Correct collet condition, spindle runout, tool projection, ramped entry, feed rate, RPM, cut depth, chip evacuation, and workholding remain essential to productive service.

Product Highlights
Downward Cutting Pressure
Downcut flute direction directs cutting forces and chip flow downward, helping support part hold-down and a cleaner top edge in compatible roughing passes.
Extended Cutting Length
The 2-1/8-inch cutting length is paired with a 1/2-inch cutting diameter, 1/2-inch shank, and 4-inch overall length.
Compatibility & Installation Notes
Confirm a clean, undamaged 1/2-inch collet or compatible holder, correct right-hand cutting rotation, adequate shank engagement, safe tool projection, machine RPM limits, feed rate, cut depth, chip evacuation, workholding, and material support before use. Downcut tools should be ramped into the work rather than plunged straight into wood. This is a roughing tool and is expected to leave a rippled edge; use a compatible finishing or profile tool when the operation requires a finished surface.
High-Feed CNC Roughing
Vortex Tool 1165 combines two-flute downcut roughing geometry with a verified 1/2-inch cutting diameter, 2-1/8-inch cutting length, 1/2-inch shank, and 4-inch overall length for compatible high-feed CNC stock-removal operations.
Correct collet fit, spindle condition, tool projection, ramped entry, feed, RPM, cut depth, chip evacuation, workholding, and a planned finishing pass are essential to achieving productive roughing performance and the intended final result.
