Extension Rod for CNC Milling Cutters
This carbon-steel extension rod lengthens the shank of milling cutters for use with CNC wood-carving routers and engraving machines. It accepts shank diameters from 8 to 12.7mm and is supplied without a cutter. The accessory is intended for woodworking and trimming operations where extra reach is required.
Practical Limits of the Shank Extension
Carbon-steel construction transmits vibration when the assembly rotates at high speed, so the machine must be started slowly and accelerated only after the rotation stabilises. Excessive speed creates inertia-induced shake that reduces cut quality and can damage the workpiece or spindle. The 8 to 12.7mm clamping range defines the only compatible cutter shanks.
Capacity and Headroom for Deep Reach Work
The rod comfortably handles standard engraving and trimming tasks that demand extended tool length within the stated shank range. It runs out when the application requires a cutter shank smaller than 8mm or larger than 12.7mm, or when the operation demands a material or precision grade beyond carbon steel.

Questions about this item
Which shank size should I choose between 8 mm and 12.7 mm?
Match the extension rod to the shank diameter of your existing milling cutter; the rod accepts cutters from 8 mm up to 12.7 mm.
What does the 12.7 mm figure mean when the rod is in my CNC router?
It is the maximum shank diameter the collet can grip, so any cutter with a shank of 12.7 mm or smaller will fit securely.
How does the right-angle drill interface affect the extension length I can use?
The right-angle drive transmits torque through the carbon-steel rod, so keep speeds low at start-up to avoid vibration that limits practical extension length.
