Extension Rod Shank Milling Cutter 12mm
This YINGHUA extension rod lengthens the shank of milling cutters for CNC wood carving routers and engraving machines. It is made from carbon steel and connects a 12mm shank to a 12mm tool holder. The package includes only the extension rod, not the milling cutter itself. Users should start at low speed and increase gradually once rotation stabilises to avoid vibration.
Woodworkers and CNC operators needing extra reach
The rod suits workshops where standard cutter shanks are too short for deep recesses or thick workpieces. It fits machines accepting a 12mm shank on both the spindle and tool side. Buyers who require a different shank diameter or a quick-change collet system should look at alternative tooling.
Carbon steel construction for rigid extension
The 12mm-to-12mm coupling maintains concentricity for light to medium routing passes in wood, plastic and similar materials. Excessive overhang or high feed rates will introduce deflection and chatter, limiting depth of cut. The design is not intended for heavy hogging or continuous high-torque metal milling.

Questions about this item
What size collet or chuck does the 12 mm shank of this extension rod need?
The rod has a 12 mm shank, so it requires a 12 mm collet or chuck on the CNC router or engraving machine.
Can I leave my existing router bits in place and just add this rod for extra reach?
Yes, the rod is designed to lengthen the shank of your current milling cutters without removing them from the machine.
How do I know the extension rod is running true after I install it?
Start the spindle at low speed and increase gradually; stable rotation without vibration shows the rod is seated correctly.
