The locking shank is a modular tool system designed for high-rigidity and high-precision machining applications. It features a threaded connection that securely fixes the cutter head to the shank, ensuring stability and accuracy. Ideal for mold, automotive, and aluminum product processing, this tool system offers exceptional performance and durability.

Key Features

1. High Rigidity and Stability

The locking shank and tool threads are precisely matched to minimize combined gaps, enhancing overall rigidity and reducing processing vibrations. For instance, when the steel shank is combined with the cutter head, the cutting force is evenly distributed, increasing blade life by 50%-80%.

2. High Precision and Concentricity

Direct thread connection eliminates the need for intermediate parts like collets, avoiding multiple clamping errors. The countersunk fitting design further ensures concentricity, with some models supporting high-speed processing up to 20,000 rpm through full grinding and dynamic balance optimization (G2.5 level).

3. Modularity and Convenience

Supports flexible combinations of "one handle and multiple heads" or "one head and multiple handles," catering to needs from roughing to finishing. Quick cutter head replacement reduces downtime and maintenance costs. Extension rods can be stacked (up to one stack) to meet lengthening requirements without causing tool vibration.

4. Optimized Structure and Durability

Quenching and hardening treatments enhance wear resistance. The through-hole design facilitates coolant circulation and chip removal, while the four-edge structure optimizes chip removal efficiency.

5. Wide Application and Cost-Effectiveness

Widely used in high-speed machining of aluminum products and molds, compatible with various blades. The cost is lower than traditional tool bars, and damaged tool heads can be replaced separately, reducing overall usage costs.
