Pass-By Clearance
The reduced diameter between the cutting edge and shank creates clearance for deep-pocket mortising and stepped cuts through thicker workpieces.


A Vortex Tool Series 2300 solid-carbide roughing pass-by router bit with a 5/8-inch cutting diameter, 2-inch cutting-edge length, 5/8-inch shank, 6-inch overall length, and 4-1/2-inch depth-of-cut capacity. Its reduced-diameter pass-by section supports deep-pocket mortise cuts and step cutting through thick materials.
This Series 2300 upcut tool combines three roughing flutes with a reduced diameter between the cutting edge and shank, allowing the bit to pass deeper into compatible workpieces for mortising, deep-pocket routing, and stepped cuts.
Designed for compatible CNC routers and routing machines using a clean, correctly sized 5/8-inch collet or toolholder. Confirm right-hand spindle rotation, sufficient shank engagement, minimum practical projection, secure workholding, RPM, feed, chip evacuation, and step-cut strategy before production use.
The Vortex Tool 2377R belongs to the Series 2300 pass-by/deep-pocket mortise upcut range and uses the catalog's three-flute roughing geometry. Pass-by tooling uses a long overall length and a reduced diameter between the end of the cutting edge and the shank, creating clearance for deeper routing operations than a conventional full-diameter body would permit.
This exact configuration uses three roughing flutes with upcut spiral geometry. The upward chip path supports chip removal from deep pockets and mortises, while the roughing profile is intended for efficient stock removal before any separate finishing pass required by the application.
The verified 2377R dimensions are a 5/8-inch cutting-edge diameter, 2-inch cutting-edge length, 5/8-inch shank, 6-inch overall length, and 4-1/2-inch depth of cut. Correct collet condition, low spindle runout, controlled tool projection, secure workholding, and suitable stepped toolpaths are essential for this extended-reach finishing tool.
Technical Specifications
The reduced diameter between the cutting edge and shank creates clearance for deep-pocket mortising and stepped cuts through thicker workpieces.
Three roughing flutes provide the verified Series 2300 cutting configuration for deep routing operations where efficient stock removal and chip clearance are the priority.
The 5/8-inch cutting diameter and 2-inch cutting length are paired with a 5/8-inch shank, 6-inch OAL, and 4-1/2-inch depth of cut.
Confirm a clean, undamaged 5/8-inch collet or compatible toolholder, correct right-hand spindle rotation, adequate shank engagement, minimum practical tool projection, machine RPM limits, feed rate, step depth, chip evacuation, and workholding before use. Upcut geometry can lift the workpiece, while the 6-inch overall length and 4-1/2-inch depth-of-cut capacity make runout control, secure workholding, and suitable step-downs especially important.
Vortex Tool 2377R combines a reduced-diameter pass-by body, three-flute roughing geometry, and upward chip evacuation for compatible deep-pocket mortise and step-cutting operations.
Correct 5/8-inch collet fit, low spindle runout, minimal practical projection, secure workholding, suitable stepped toolpaths, and effective chip evacuation are essential to stable performance.
