Cermet Series · Finishing
The T-11A Cavity Tool is a dedicated reamer for cartridge valve manifolds. It is a high-precision cutting cavity tool designed for machining holes in hydraulic cartridge valve manifolds, mainly used to improve the dimensional accuracy, geometric accuracy, and surface finish of multi-diameter bores. Designed for precision machining of cartridge valve cavities in Sun Hydraulics hydraulic manifolds, including reaming of guide bores, oil passage bores, and valve seat bores. It ensures high bore accuracy and meets the strict sealing and functional requirements of hydraulic systems. Versatile applications: One tool body can efficiently perform precision reaming of multiple hole diameters. Because the cutting section uses a brazed cermet insert plate, wear is minimized and tool life is extended. Cavity Tool Type: HSS A Type / Morse Taper Shank B Type / Solid Carbide C Type / Indexable Insert D Type / Brazed Insert Plate E Type / Brazed Cermet R Type / Brazed PCD F Type.

Design details engineered for accuracy, tool life and process stability.
Thanks to excellent wear and heat resistance, brazed cermet reamers last longer than conventional tools, reducing replacement frequency and cost.
Cermet materials provide extremely high hardness and wear resistance, maintaining excellent cutting performance under high-load and high-temperature conditions.
Cermet maintains its physical and chemical properties at high temperatures, making it suitable for high-temperature alloys and other difficult-to-machine materials.
The T-11A D81021 Brazed Cermet Cavity Tool features a precision design and high-performance materials, maintaining stable cutting performance over long periods to improve machining accuracy and tool life.
The T-11A D8101 complies with Sun Hydraulics cartridge valve technical standards, including control valves, diverter valves, relief valves, directional valves, and similar applications. It is suitable for valve bodies made from heat-treated alloy steel above HRC 35.
Compared with solid carbide cavity tools, it offers higher wear resistance and supports higher spindle speeds and feeds. Hole surface roughness typically reaches Ra 0.4 or better, meeting the high sealing requirements of hydraulic components.
