The D3D4 Tungsten Steel Grinding Head is a cemented‑carbide rotary burr designed for slotting machine edge processing. It features a 4 mm grinding head diameter attached to a 3 mm shank, and each box contains twenty pieces. The supplier describes the tool as delivering low wear on metal and higher wear resistance on stainless steel, positioning it as a durable alternative to high‑speed‑steel cutters.
The grinding head is manufactured from tungsten carbide (WC‑Co) which typically attains a hardness of around 90 HRA, providing superior wear resistance. In the machining industry, such heads are classified under ISO 1832 grade 6, offering excellent rigidity for high‑speed slotting. Typical tolerance on the head diameter is ±0.02 mm, and recommended spindle speeds range from 10 000 to 30 000 rpm to balance material removal rate and tool life. The design is compatible with both desktop and CNC slotting machines.
Primary users include mold makers, precision machining shops and metal‑fabrication facilities that require consistent edge quality in metal and stainless‑steel components. The supplier notes flexible bulk ordering and ships the heads in cardboard boxes with protective inserts. Buyers should verify the exact MOQ, lead‑time and incoterms such as FOB or CIF with the supplier before placing an order.

Buyers should first confirm that the D3D4 grinding heads are produced from WC‑Co cemented carbide meeting the typical HRA 90 hardness level, and request a material test report or certification such as ISO 1832 grade 6. Because the listing does not state the exact tolerance or hardness value, obtaining these details directly from Yao Star ensures the tools will perform as expected in high‑wear slotting operations.
The supplier mentions bulk shipment in cardboard boxes with protective inserts, but does not disclose lead‑time or incoterm specifics; importers need to ask for an estimated production lead‑time, the preferred incoterm (FOB, CIF, etc.) and the payment method, whether T/T, L/C or another arrangement. Aligning on these logistics early helps avoid delays and allows the buyer to coordinate freight forwarding and customs documentation.
When the grinding heads reach the destination, a visual inspection should verify that the heads are free from chips or cracks and that the packaging is intact. A hardness test and dimensional check against the stated 4 mm head and 3 mm shank tolerances should be performed, and the supplier’s test report should be reviewed. Keeping these inspection records will facilitate quality assurance and support any warranty claims.
