Precision Carbide Machining Services Tungsten Carbide Machined to Your Exact Drawing Diamond grinding and EDM for custom wear parts, tooling components, and precision carbide parts. ISO 9001:2015 certified. Tolerances to ±0.0002″.
|
Extramet Products provides precision tungsten carbide machining services for custom wear parts, tooling components, and high-performance industrial applications. Because of its extreme hardness (85–95 HRA), tungsten carbide cannot be machined using conventional cutting tools. We utilize specialized diamond grinding and Electrical Discharge Machining (EDM) processes to shape, cut, and finish carbide components to exacting specifications.
From prototype development to high-volume production runs, we machine both our own stock carbide material and customer-supplied blanks, delivering consistent precision, superior surface finishes, and fast turnaround under our ISO 9001:2015 quality system.
Tungsten Carbide Machining Capabilities
Our facility is equipped to handle the unique challenges of machining hard, brittle materials. We offer a complete suite of carbide machining processes to achieve complex geometries, tight tolerances, and mirror finishes.
| Machining Process | Best Used For | Typical Tolerance | Surface Finish (Ra) |
|---|---|---|---|
| Centerless Grinding | High-volume OD grinding of rods, pins, and simple cylinders | ±0.0002″ | 2–4 µin (Polish) |
| CNC Cylindrical Grinding | Complex OD profiles, multiple diameters, tight concentricity | ±0.0002″ | 4–8 µin |
| Surface Grinding | Flat surfaces, squaring blocks, parallel faces, and wear plates | ±0.0002″ | 4–8 µin |
| Wire EDM | Complex 2D profiles, through-holes, slots, and extrusion dies | ±0.0005″ | 12–16 µin |
| Sinker EDM | Blind cavities, hex holes, internal splines, and complex 3D shapes | ±0.0005″ | 16–32 µin |

Carbide Grades & Material Selection
The cobalt binder content of a tungsten carbide grade directly affects its hardness, toughness, and machinability. Extramet works with a broad range of carbide grades and can machine from supplied material, in-house preforms, or Extramet blanks.
| Grade Type | Cobalt Content | Hardness (HRA) | Best For |
|---|---|---|---|
| Ultra-fine grain | 6–8% | 92–93 | Precision wear parts, cutting edges, gauging |
| Fine grain | 8–10% | 91–92 | General wear parts, dies, punches, nozzles |
| Medium grain | 10–13% | 89–91 | Mining, oil & gas, impact-resistant wear parts |
| Coarse grain | 13–16% | 86–89 | Heavy impact applications, rock drilling, forming dies |
