Longer Durability Roller Coal Cutter Picks Good Sealed For Tunnel Boring Machine

Coal cutter picks is made of high quality cold extrusion 42CrMo, high density not decarburization. Numerical control lathe processing ensures consistent size. With special heat treatment process of 40-45 degrees, its surface is almost no oxidation, tooth head using isothermal quenching process, its hardness doesn't reduce. PDC cutter inserts the teeth head, makes the head more wear-resistant and hardness.

Production of cemented carbide by formal domestic companiesYG11C, stable quality can accord customer needs to add welding wear-resisting layer, hardness reaches more than 65 degrees. Teeth body and head is forged by state-of- the art manufacturing process. All these make the bit head not fail easily and make it have a long service life.

Include all kinds of round cutter bit and flat cutter bits for excavate coal machine as the replacements of kennametal ( Such as U47, U82, U84, U170, U92, U94, U95, U98,U172 and coal bolting bit and coal bolting rod)
