Cold Forming

Long Wall Miner Bits

Cold-formed longwall miner bit components engineered for underground coal mining applications where wear resistance, dimensional consistency, and durability are critical to continuous production.

Long Wall Miner Bit

We manufacture precision components used in long wall miner bits and long wall shearer systems operating within underground coal mining operations. These Made in the U.S.A. cold-formed mining components are designed for continuous cutting, high-impact loading, and abrasive conditions typical of underground mining equipment and mining machinery used throughout the mining industry.

Cold-formed long wall miner bit components are engineered for strength, dimensional accuracy, and repeatable performance in underground mining environments. Designed to support conical cutting geometries used in long wall shearer systems and underground coal mining equipment, these components maintain structural integrity under high loads, repeated impact, and abrasive material exposure. Preserved grain flow from cold forming supports consistent geometry, extended service life, and reduced unplanned downtime in sustained cutting operations.

Component Range: 43–48 mm*
