YINGHUA 10pcs Two Flute Straight Slot Bit 3.175X2X8X38

10-piece tungsten-steel router bit set

This set contains ten two-flute straight slot bits made from tungsten steel for CNC routing work. Each bit measures 3.175 mm shank by 2 mm cutting diameter with an 8 mm flute length and 38 mm overall length. The solid carbide construction suits engraving and cutting tasks on acrylic, PVC, nylon, resin, wood and plywood. The pack is sold new and intended for industrial use only.

Two-flute geometry and 3.175 mm shank

The straight two-flute design evacuates chips cleanly during fine detail work and reduces vibration in handheld or table-mounted routers. A 3.175 mm shank fits standard collets without adapters, letting you swap bits quickly between jobs. Tungsten steel retains edge life longer than high-speed steel when cutting abrasive composites such as fibre-reinforced plastics. The 38 mm overall length keeps the tool rigid in shallow-pocket operations.

Replaces worn high-speed steel bits

Upgrading from dull high-speed steel cutters restores clean edges on acrylic and plywood without burn marks. The carbide tips stay sharp through repeated production runs, so the change pays off when batch sizes exceed a few dozen parts. Shops that only cut soft pine occasionally will not see a cost benefit over cheaper steel bits. The set is not for hobbyists under 18 or for any hazardous material cutting.
