Vortex Tool Series 1200 Left-Hand Two-Flute Upcut Finishing Spiral Router Bit – 3/8 in Diameter x 1-1/4 in Cutting Length
Left-Hand Two-Flute Upcut
Finishing Spiral
A Vortex Tool Series 1200 left-hand two-flute solid-carbide upcut finishing spiral with a 3/8-inch cutting diameter, 1-1/4-inch cutting-edge length, 3/8-inch shank, and 3-inch overall length. Its helical cutting geometry is designed for smooth-edge routing, a clean bottom finish, and upward chip evacuation in compatible general-purpose applications.
Main Product Description
The Vortex Tool 1240L is the left-hand-rotation variant in the Series 1200 two-flute upcut finishing spiral range. Vortex positions this geometry as a popular general-purpose finishing design for routing applications where a smooth edge cut is required and no specialized cutting condition calls for a different flute configuration.
Its helical cutting edge reduces the amount of material contact while the tool is engaged. The upcut spiral draws chips upward from the cut and supports a smooth bottom finish in compatible grooves, dados, profiles, and through-routing operations when the tool is matched correctly to the material and toolpath.
The verified 1240L configuration uses a 3/8-inch cutting-edge diameter, 1-1/4-inch cutting-edge length, 3/8-inch shank, 3-inch overall length, and left-hand rotation. Correct collet condition, spindle runout, tool projection, feed rate, RPM, cut depth, chip evacuation, and workholding remain essential to finish quality and tool life.
Best Fit Applications
Product Highlights
Two-Flute Finishing Geometry
The Series 1200 design is intended for smooth-edge cutting across a broad range of compatible general-purpose routing applications.
Upward Chip Evacuation
The upcut spiral carries chips upward from the cutting zone while supporting a smooth bottom finish in compatible routed features.
Compact Imperial Configuration
The 3/8-inch cutting diameter and 1-1/4-inch cutting length are paired with a matching 3/8-inch shank and 3-inch overall length.
Compatibility & Installation Notes
Confirm a clean, undamaged 3/8-inch collet or compatible toolholder, correct left-hand spindle rotation, adequate shank engagement, safe tool projection, machine RPM limits, feed rate, cut depth, chip evacuation, workholding, and material support before use. Upcut geometry draws chips and cutting forces upward, so secure part hold-down and suitable dust extraction are important for stable routing and consistent finish quality.
Clean General-Purpose Finishing
Vortex Tool 1240L combines left-hand two-flute upcut finishing geometry with a verified 3/8-inch cutting diameter, 1-1/4-inch cutting length, 3/8-inch shank, and 3-inch overall length for compatible precision CNC routing operations.
Correct collet fit, spindle condition, tool projection, feed, RPM, cut depth, chip evacuation, workholding, and material selection are essential to achieving the intended smooth edge and clean bottom finish.
