Precision-ground tungsten carbide blades are chosen when the cut is limited by abrasive wear, edge rounding, or geometry drift. We supply carbide blades in multiple configurations—especially circular slitter blades (disc knives) and rotary cutting blades—made to drawing and inspected to your specification.

• Circular slitter blades
• Disc blades
• Rotary cutter blades
• Industrial machine blades
• Custom by drawing
• Wear-focused carbide grades

Precision-machined tungsten carbide balls and carbide valve seats are used where a ball-and-seat sealing interface must survive abrasive particles, erosive flow, repeated cycling, and (often) corrosion.

Best fit for:

● Abrasive / sand-containing wells, viscous oil service, offshore fluids, and high-wear pump valve duty (leakage growth driven by seat/ball wear).

● Severe-service valves & flow controlwhere seats/balls/trim face erosion, cavitation damage, or corrosion-assisted wear.

● Custom machiningfrom drawings (ball size, seat geometry, sealing angle/radius, and inspection items aligned to your spec).

Precision wire drawing tooling engineered for abrasive wear + high contact loads. We supply tungsten carbide drawing dies in a variety of specifications—round or shaped profiles—commonly used for tungsten wire, molybdenum wire, stainless steel wire, alloy wire, and cable wire.

• Wire drawing dies
• Carbide die nibs (inserts)
• Round & shaped profiles
• Fine wire & precision wire
• Metalforming tooling

Carbide button inserts engineered for abrasive wear + cyclic impact in drilling duty—widely used in oilfield drilling and rock drilling systems such as roller cone (TCI) bits, DTH bits, top hammer/drifter bits, and geotechnical drilling tools.

• P type flat-top bits
• Z type coinspherical bits
• X type wedge bits

Customization of various types of tungsten carbide buttons

Tungsten carbide mining bits are wear-resistant carbide components used in coal cutter drilling tools and mining machinery tools. In practice, they are commonly supplied as carbide button inserts and carbide cutting tips used in rock tools and mining tools across quarrying, mining, tunneling, construction, and civil engineering.

Mining inserts fail for different reasons. If you can identify the dominant issue, selection gets simpler.

● Fast edge wear / rounding:abrasion-dominant

● Chipping / breakage:impact, stress concentration, or assembly stress

● Insert loss:pocket fit / brazing / pressing process issue

● Localized “washout”:erosion from high-velocity particles and poor flow guidance

Tungsten carbide products for geological prospecting and exploration drilling tools—engineered for abrasive wear, high contact stress, and cyclic impact in real drilling environments.

Typical selection drivers

● Abrasive wear:hard minerals, sandstones, quartz-bearing formations

● Impact/chipping:broken ground, boulders, high percussive energy

● Erosion & flushing:high-velocity cuttings flow can “wash” gage/shoulders

● Corrosion risk:groundwater, brines, chemically active environments

● Fit & retention:press-fit pockets, brazing design, tolerance stability
