Flat Bottom Engraving Bits

Flat Bottom Engraving Bits are specialised CNC tools with a square‑bottom cutting profile, supplied by Dongguan Haiying Cutting Tool Co., Ltd. The bits are designed for engraving double‑color board, ABS, acrylic and PVC sheets. Supplier is located in Tiankeng Village, Hengli Town, Dongguan, Guangdong, China, operating from a dedicated workshop. The catalogue lists diameters from 0.1 mm to 2 mm and angles ranging 10° to 60°, with a standard shank of 3.175 mm and overall length 33 mm.

Bits are typically fabricated from solid carbide, a material that retains sharpness on hard plastics and offers high wear resistance. Standard coatings such as TiAlN are often applied to improve heat resistance, though coating specifics should be confirmed with the supplier. Typical spindle speed limits are up to 30 000 rpm, while recommended feed rates lie between 0.02 mm and 0.10 mm per revolution. The square‑bottom geometry enables consistent depth control for fine characters and complex patterns.

These tools are favoured by signage manufacturers, prototype engineers and small‑batch electronics makers who require precise surface detailing. Importers should verify the exact diameter, angle and coating required for their application before placing an order. MOQ, lead time and incoterms are not disclosed in the listing and must be confirmed directly with Dongguan Haiying Cutting Tool Co., Ltd.
