Import Flat-Bottom Junk Mill To Mill Downhole Junk — Buy in Bulk from Supplier in China

The Flat-bottom Junk Mill is a downhole tool designed to grind and remove metal debris such as bolts, nuts, and tool joints from deep-well pumps. Its body is forged from high-strength alloy steel and the cutting surface is clad with super-tough sintered tungsten carbide. The mill is offered in outer diameters ranging from 3 ¾ in to 18 ½ in, with optional blade configurations of zero, three, four, five or six blades. Lengths are supplied between 10 in and 36 in and the design may be convex, concave, flat-bottom or offset according to the required milling profile.

Carbide particles are welded onto the surface to provide a self-milling action that reduces wear during prolonged operation. In the oil-field sector, similar junk mills typically use alloy steel conforming to ASTM A335 P91 and carbide hardness around 1800 HV, which are regarded as standard for high-temperature, high-stress environments. Dimensional tolerance on the outer diameter is usually ±0.015 in, ensuring a reliable fit on standard downhole housings. The mill’s construction tolerates temperatures up to 350 °C, matching the thermal profile of most drilling operations.

Service companies that maintain drilling rigs and pump‑jack installations purchase these mills to keep circulation systems clear of obstructive hardware. The supplier does not publish minimum order quantities, price brackets or lead‑time, so buyers should request those details directly. Packaging is typically crate‑packed with protective padding, and the shipment can be arranged under FOB or CIF terms as agreed with the supplier. Confirm the exact specifications, certification documents and payment conditions before confirming any purchase.
