BIG DAISHOWA Expands Angle Head Lineup with New TAG90 Centre-Through-Coolant Model!

BIG DAISHOWA, a global leader in precision tooling and workholding solutions, has unveiled the latest addition to its 90-degree angle head lineup: the TAG90 centre-through-coolant model. Designed with high-performance machining in mind, the new model—along with the AG35 high-pressure coolant adapters—marks a significant step forward in tool efficiency, chip evacuation, and machining accuracy.

At the heart of the TAG90’s design is its centre-through-coolant capability, which delivers coolant directly from the machine spindle to the cutting edge. Unlike traditional systems that route coolant through the stop block, the TAG90 eliminates unnecessary pathways, ensuring more efficient cooling, improved lubrication, and optimized chip evacuation. This direct delivery system supports coolant pressures of up to 1,000 PSI, making it suitable for today’s most demanding machining environments.

By enhancing cooling at the cutting zone, the TAG90 not only extends tool life but also allows manufacturers to run higher cutting speeds and feeds with confidence—translating into greater productivity and reduced cycle times.

BIG DAISHOWA’s new release comes in two configurations, catering to different machining needs:

• Build-Up Type – Designed for maximum versatility, this option accepts interchangeable AG35 adapters. Users can switch between toolholding systems such as the New Baby Chuck and Side Lock, providing flexibility for different applications without sacrificing rigidity or precision.
• HMC Type – Engineered for heavy-duty applications, this high-rigidity milling chuck configuration is built to withstand demanding operations. It ensures stability and accuracy when machining complex parts, even under challenging conditions.

One of the biggest advantages of angle heads is their ability to expand a machine’s capabilities without requiring additional setups. The TAG90 allows shops to perform both vertical and horizontal machining in a single setup, giving operators better access to difficult-to-reach part features. This not only reduces handling time but also eliminates potential errors caused by multiple re-clampings, ensuring higher overall precision.

For industries such as aerospace, automotive, medical, and die-mold—where complex geometries and tight tolerances are the norm—the TAG90 provides a reliable and efficient solution to streamline operations.

With its combination of centre-through high-pressure coolant, flexible toolholding options, and robust construction, the TAG90 sets a new benchmark for angle head performance. Shops can expect:

• Improved chip evacuation for longer tool life and reduced downtime.
• Higher productivity through faster machining speeds and fewer setups.
• Greater accuracy by minimizing errors associated with multiple fixturing.
• Increased versatility, thanks to interchangeable adapters and dual configuration choices.

BIG DAISHOWA’s introduction of the TAG90 demonstrates the company’s ongoing commitment to delivering solutions that push the boundaries of metalworking efficiency. By combining advanced coolant delivery with a rigid, adaptable design, the TAG90 angle head enables manufacturers to tackle complex machining tasks with precision, confidence, and speed.
