YINGHUA 4×17×45mm UP DOWN Compound Single Flute Spiral Carbide Mill Tool Cutters

Tungsten Carbide CNC Router Bit

This single-flute compression cutter is designed for CNC machinery and suits operators who need precise cuts in acrylic, PVC, density board and wood board. The tungsten steel construction provides hardness for industrial routing tasks. It is not intended for hand-held drilling or for users under 18 years of age.

4 mm Shank Compression Geometry

The up-down flute arrangement compresses material from both faces to reduce tear-out on double-sided panels. Cutting length is limited to the 17 mm flute section and overall tool length is 45 mm, so deep pockets or thick stock require multiple passes. The right-angle drill format means it fits standard collets but cannot reach inside tight internal corners.

Solid Carbide Single-Flute Build

One-piece carbide body resists deflection better than brazed-tip alternatives and the single flute clears chips efficiently in softer plastics and wood composites. No bearing or guide is included so edge-following cuts need a template or fence. The uncoated surface may wear faster in abrasive materials such as fibre-reinforced panels.
