The AT3830 Series Surface Continuous Miner Bits are engineered with a wide collar and step shank design, specifically developed for heavy-duty continuous mining equipment. These advanced miner bits address common issues like inadequate shank strength and excessive bit holder wear, significantly improving reliability and operational efficiency in tough environments.

Product Features:

• Wide Collar Protection

The widened collar design provides full protection for the bit holder and sleeve, extending the service life of supporting components—ideal for demanding surface miner picks applications.

• Reinforced Step Shank

The step shank structure boosts overall strength, enabling the continuous miner bits to withstand higher torque and impact loads.

• External Circlip System

Allows quick on-site replacement, reducing equipment downtime and simplifying maintenance.

• Designed for Heavy-duty Conditions

Optimized for high-strength, continuous mining tasks in harsh operating environments.

• Stress Distribution Optimization

The step shank reduces stress concentration, lowering the risk of fatigue failure in miner bits.

• Standardized Compatibility

Complies with industry-standard interface sizes, ensuring compatibility with mainstream continuous miner bits systems and equipment.
