Diamond Orifice 12749-009 Good Quality WaterJet Cutter Parts

The Diamond Orifice 12749-009 is a premium, high-precision component designed to produce a focused, ultra-high-pressure water stream in abrasive and pure Waterjet Cutting Systems. Serving as the first stage of the cutting head assembly, this orifice directs water through a microscopic diamond aperture to form a stable, high-velocity jet — the foundation of precise, efficient, and clean cutting performance.

Manufactured using industrial-grade synthetic diamond mounted in a stainless steel or tungsten carbide housing, the 12749-009 diamond orifice offers unmatched wear resistance, dimensional accuracy, and long service life. The diamond aperture is laser-drilled and polished to ensure a perfectly round, smooth jet stream, minimizing turbulence and maximizing cutting power even under pressures up to 60,000 psi (4000 bar).

The Diamond Orifice 12749-009 is compatible with major waterjet brands including KUNDA, KMT, FLOW, and OMAX, and fits standard orifice assemblies, mixing chambers, and nozzle bodies. It pairs perfectly with Mixing Tubes (e.g., 11040-030-30, 11040-040-30) to deliver an extremely precise abrasive-water jet for fine or heavy-duty cutting applications.

Ideal for industries such as metal fabrication, stone cutting, ceramic machining, glass manufacturing, and composite processing, this orifice ensures superior accuracy, longer component lifespan, and reduced maintenance costs — essential for operators seeking consistent, top-quality waterjet performance.
