Indexable tool holders are critical components in high-performance machining applications across industries such as automotive, aerospace, and general manufacturing. However, conventional manufacturing methods—constrained by structural and process limitations—often struggle to meet the increasing demands for efficiency, durability, and cost-effectiveness. Leveraging BLT’s metal additive manufacturing (AM) technology, we are overcoming these challenges and driving breakthroughs in design innovation, operational efficiency, and production economics.
BLT’s metal 3D-printed indexable drill bits are produced at full build capacity, with each unit measuring 31×32×126mm. Fabricated from tool steel using the BLT-S400 machine, the process achieves complete one-step formation of 115 pieces per batch with a total build time of just 48 hours.
Conventional tool holders typically employ simple straight cooling channels and rely on bulky solid structures, which restrict heat dissipation efficiency and tool lifespan while adding unnecessary weight and inertia. BLT’s additive manufacturing solutions enable the production of complex conformal cooling channels, significantly enhancing thermal management efficiency. Through internal lightweight structures and cavity designs, the rotational inertia of components is effectively reduced, thereby optimizing dynamic performance and lowering machining energy consumption.
BLT’s additive manufacturing process enables near-net-shape production, achieving high-precision component fabrication in a single step. This significantly shortens prototype development cycles while accommodating small-batch customization needs. Utilizing Powder Bed Fusion technology, material is precisely deposited only where required, dramatically improving material utilization, reducing waste generation, and lowering production costs.
Moving forward, BLT will continue to advance integrated manufacturing solutions for highly complex cutting tools, driving the metalworking industry toward greater efficiency and lightweight innovation.
