h6 330mm length extruded and CIP press tungsten
carbide rods polished for solid drilling tools
Description & Application:
Tungsten Carbide rod are widely used in endmills, drills, PCB drills, PCB routers etc. With several
years’ development, our carbide rod blanks with our good quality and competitive price,and have been
widely recognized by worldwide makers of cutting tools, like in turkey, russia, india, finland, isreal. We are
looking forward to establish new business with new customers. We provide various size and recommend
grade information for option. the standard length 330mm and 310mm, and cut into different length for
customers requested.
Tungsten carbide rod blanks
1. Material includes ISO K10, K20, K30 which is equal to our LX25, LBC20 and LBC25 grade. we with
the produce all kinds of ground carbide rods with h6 tolerance
1.1 LX25(similar to yg10x, but better than yg10x) :It is suitable for machining common steel, cast iron,
stainless steel, heat‐resistant steel , nickel
based alloys and titanium alloys, etc. It is recommended for making conventional tools, such as twist drills,
end drills, screw taps, etc.
1.2 LBC25:It is suitable for machining titanium alloy , heat‐resistant alloys, stainless steel, hardened steel,
grey cast iron, glass‐fiber Reinforced plastics, composite materials, etc. It is recommended to make drills
and milling tools, etc.
2. Undertake orders of non-standard sizes at customer's requests.
3. Diameter: 3-40mm (CIP production)
4. Standard Length: 310/330mm
Production Process:
Below are the production processes of tungsten carbide rods, to ensure high quality, we assureed our
customers that:
1. All materials are tested in terms of density, hardness and T.R.S before use.
2. Every piece of product goes through in-process and final inspection.
3. Every batch of product can be traced.
