YINGHUA 4X17X45mm Carbide Mill Cutter
This single-flute carbide mill cutter is designed for CNC routing applications. It suits workshops and makers who need precise profiling on wood-based panels and plastics. The up-down compound geometry reduces tear-out on both faces of the workpiece. It is not for buyers needing multi-flute tools for heavy chip evacuation or high-feed roughing.
17 mm cutting length with 45 mm overall reach
The 17 mm flute length provides enough depth for typical sheet-goods profiling and pocketing. The 45 mm total length fits standard ER collets and tool holders without excessive overhang. It runs out of reach on thicker stock or deep cavities that exceed the flute length. Users cutting material stacks beyond 17 mm will need a longer tool.
Tungsten steel body with blue coating
The tungsten steel construction resists wear when cutting abrasive composites such as density board and PVC. The blue coating aids chip identification and reduces built-up edge on acrylic. The single-flute design demands rigid spindle run-out and secure collet clamping to avoid chatter. It is not suited for hand-held routers lacking precision collet systems.

Questions about this item
Will the 4 mm shank fit the collet on my older CNC router?
The cutter has a 4 mm shank diameter, so it fits any collet or chuck that accepts 4 mm tooling; check your machine's collet size before ordering.
How can I confirm the up-down spiral is cutting cleanly on both faces of the board?
Run a test cut in scrap material and inspect the top and bottom edges — both should show clean, tear-free surfaces if the compression geometry is working correctly.
Does the single cutter come with any collets, washers or spare flutes in the package?
The box contains only the 1-piece up-down single-flute carbide cutter; collets, washers or additional flutes must be purchased separately.
