3.1 Product Overview

Series B introduces a revolutionary approach to cost-effective hole drilling through Alpha's proprietary Bi-Metal Joint Technology. By combining a precision-engineered drilling edge with an optimized steel body, Series B delivers performance that rivals solid carbide drills at a fraction of the cost.

The innovative Bi-Metal construction utilizes Alpha's unique joining process that creates a metallurgical bond between the carbide cutting portion and the high-quality steel s hank. This breakthrough technology preserves the cutting performance of premium carbide while dramatically reducing material costs — achieving the target of 50% cost reduction without compromising hole quality.

3.2 Key Featuresand Benefits

Alpha Unique Drilling Edge and Bi-Metal Joint Technology: The proprietary bi-metal joining process ensures a robust, permanent connection between the carbide tip and steel body, delivering consistent performance and eliminating the risk of tip separation under load.

Cost-Optimized Design: Purpose-engineered as a cost-effective hole drilling solution specifically for applications where the drilled diameter is less than 8mm — the sweet spot where material savings have maximum impact.

Productivity-Cost Balance: Achieves the perfect combination of high productivity and low tooling cost, making it an ideal choice for high-volume production environments where tool consumption is significant.

Equivalent Performance: Delivers equivalent drilling performance to solid carbide alternatives at 50% lower cost, providing an immediate and substantial reduction in per-hole tooling expenditure.
