YINGHUA Two-Flute Carbide End Mill

The YINGHUA two-flute straight-slot end mill is a tungsten-steel cutter designed for CNC engraving and cutting. It handles acrylic, PVC, nylon, resin, wood and plywood with precision. The tool is sold as a single piece for industrial use only.

Two-Flute Geometry Limits Chip Clearance

Two flutes provide a straight slot that evacuates chips in a single direction, which restricts feed rates in deep or high-volume cuts. The right-angle drill format means the shank and cutting length are fixed, so the tool cannot reach features deeper than its own flute length. Users needing faster material removal or multi-directional chip flow should consider a different flute count.

4 mm Cutting Diameter Sets Minimum Feature Size

The 4 mm diameter determines the smallest internal radius and slot width the cutter can produce. Any design requiring finer detail or narrower channels cannot be machined with this tool. Builders who need smaller features must select a cutter with a reduced diameter.

Questions about this item

What does the 4x4x25x45 sizing mean for my CNC setup?

The 4 mm shank and 4 mm cutting diameter fit 4 mm collets. The 25 mm flute length gives the depth of cut, while the 45 mm overall length clears standard tool holders.

How does the tungsten steel material perform when engraving acrylic and wood?

Tungsten steel keeps a sharp edge longer than high-speed steel, so fine details in acrylic, PVC, nylon, resin, wood and plywood stay clean with less frequent re-sharpening.

What does the two-flute straight-slot geometry limit in practice?

Two straight flutes evacuate chips well in softer materials but can clog in deep slots or high-feed cuts, so use lighter passes and clear chips regularly.
