Compact Compression Router Bit

The YINGHUA 3.175X17X38mm Rainbow 3A UP DOWN Compound Single Flute Spiral Carbide Mill Tool Cutter is a solid carbide router bit designed for CNC machinery. Its up-down compression geometry shears both faces of the workpiece to prevent tear-out on laminated or veneered sheet goods. The tool suits woodworkers and sign makers who need clean edges on double-sided materials.

Ideal for Double-Sided Sheet Work

This bit serves CNC operators cutting acrylic, PVC, density board, wood board and similar panels where both surfaces must remain splinter-free. The single-flute design clears chips efficiently in softer substrates. It is not suited for buyers who need multi-flute tools for faster feed rates in hardwoods, or for anyone requiring a shank diameter other than 3.175 mm.

3.175 mm Shank Diameter

The cutter fits collets or ER holders sized exactly to 3.175 mm. A 17 mm cutting length and 38 mm overall length define the reach and clearance envelope. Verify that your machine’s tool holder and Z-travel accommodate these dimensions before purchase.

  • Precise cuts with 3.175 mm shank diameter
