YINGHUA 1piece Two Flutes Straight Slot End Mill 4x4x17x45

Single Carbide End Mill for CNC Wood Engraving

This single two-flute straight-slot end mill is made from tungsten steel for CNC engraving and cutting. It handles acrylic, PVC, nylon, resin, wood and plywood in light-duty routing jobs. The cutter suits hobbyists and small-shop operators who need a replaceable tool for fine detail work.

Limited to Light Materials and Shallow Passes

The carbide construction resists wear but the tool is intended for soft, non-ferrous materials only. It cannot cut metals, stone or hardened composites without rapid edge failure. Maximum cutting depth per pass is constrained by the 17 mm flute length, so deep pockets require multiple shallow steps.

Direct Shank Fit for Standard Collets

The cutter mounts directly into any ER or collet chuck that accepts a 4 mm shank, so no adapters are needed. Common issues arise when the tool is run at excessive feed rates or used on unsupported stock, which causes chatter and premature flute breakage. Users under 18 years must not operate the tool.
