A standard product is tungsten carbide rod precision-finish ground to h6 tolerance. A variety of highest quality rod carbide grades are available. All rods have great performance in making cutting tools such as end mills, drill bits, etc. Tungsten carbide rod applications include drill bits, end mills, and reamers. Custom diameters and length are also available in these grades as well as metric sizes. We manufacture tungsten carbide rods. Contact me: eva.ling@mj-metalproducts.com

Tungsten Carbide Rods for PCB Tools:
Recommended applications of the grades for PCB tools:
Grades ISO Code Applications Recommended
YF06 K05-K10 Suitable for machining composite materials, such as aluminum
magnesium alloys, plastics, reinforced plastics and carbon fiber,
iron-based alloys etc. It is recommended for making big PCB
drills of Φ3.2-6.3mm, micro drills of Φ0.8-3.2mm, micro milling tools
and reamers etc.
YU06 K05-K10 Suitable for machining glass fiber, wood, plastics, and
aluminum-magnesium alloys etc. It is recommended for making
various solid carbide tools and PCB micro drills, micro milling
tools & it is an optimal grade for PCB micro drills & micro milling
tools.
YH6F K05-K10 It is developed with Nomi composite powder with
comprehensive properties of more even grain size, higher
strength, hardness and toughness etc. it is especially suitable
for making PCB micro drills of Φ3.0-0.5mm.
YU08E It is suitable for making glass fiber, wood, plastics, paper, brass
etc. It is recommended for making PDB drills of Φ0.3-0.5mm
