Horn has unveiled an upgraded tool holder for its 229 grooving system, combining the best features of previous designs into a single, more versatile unit. The innovative holder features two internal coolant delivery options – either through a threaded side port to the insert clamping finger or directly to the insert flank face – enabling high-performance operations across internal, external, face grooving, and parting applications.
Compact Design with Multiple Size Options
The new square shank tool holder maintains Horn’s reputation for compact yet robust designs, available in three standard sizes (16x16mm, 20x20mm, and 25x25mm) to accommodate various machine setups. All holders support cutting widths ranging from 3.0mm to 8.0mm and are stocked for immediate delivery, minimizing downtime for manufacturers needing quick replacements or system upgrades.
Engineered for Precision and Durability
Constructed from high-strength steel, the holders ensure exceptional precision in insert seating while delivering extended service life. Notably, the grooving depth capability remains independent of holder size, providing consistent performance across the product range. This design approach allows operators to maintain cutting parameters regardless of the specific holder size selected for their application.
Optimized for High-Performance Machining
The dual coolant path configuration addresses one of grooving operations’ most critical challenges – effective chip evacuation and heat management. By offering alternative coolant delivery methods in a single holder, Horn provides machinists with the flexibility to optimize cooling based on specific workpiece materials and cutting conditions, potentially improving both tool life and surface finish quality.
Immediate Availability Supports Production Needs
With all variants available from stock, Horn demonstrates its commitment to supporting manufacturers’ just-in-time production requirements. The enhanced 229 system represents Horn’s continued focus on developing practical solutions that combine innovative engineering with real-world usability, helping shops maximize productivity in demanding grooving applications across aerospace, automotive, and general machining sectors.
