Prodcut Descriptions :

Our tungsten carbide needles pins are perfect for filing precise shapes into carbon fiber.
The needle pins are made from mild steel with tungsten carbide welded onto them. The needle pins will cut in both directions meaning they will remove material much quicker than conventional needles and leave a clean edge without fraying or cracking carbon fiber or other composites.

The tungsten carbide is incredibly hard wearing and will not lose its edge or wear off. These tools will provide you with years of faithful service and are a must have for detailed carbon fiber work.



Grade Performances:


Grade Hardness  T.R.S Density Performance & Application Recommended
HRA N/mm² g/cm3
YG6X 91.5 ≥3500 14.9 Has wear resistance higher than YG6,used for processing hard wood,original wood,aluminum section bar,brass rod and cast iron.
YG8 89.5 ≥3200 14.7 Wear and percussion resistance,used for processing hard wood,soft wood,ferrous and non-ferrous.
YG10X 90 ≥3650 14.4 Wear resistance and strength comparatively higher,suitable for processing cast iron,non-ferrous,metal and non-metallid materials.
YS2T 92 ≥3850 14.5 Fine carbide,High wear resistance,high bending strength,high resistance to bonding,high thermal strength. Machining of refractory alloys,stainless steel and high manganese steel,etc.               

How to use it ?

Suggested Uses: This half round needle is one of the most useful shapes and is perfect for smoothing out the inside of curved cuts (like cuts for dials), cutting tools, drill bits and finishing recesses cut in dash panels for lights etc. It is also invaluable for finishing rounded slots in bonnet scoops or engine bay mods.

Open up a hole (if required) with a drill or wheel first then use the needle in a conventional way to finish a slot or edge, working gently and smoothly and we can offer high quality tungsten carbide bar and tungsten carbide needle according to customers’ requirement.
