Product Description

HighlightsWe offer various types of collet and can also customize products
Engineered with a specialized sealant to prevent coolant leakage, ensuring optimal internal cooling performance.
Manufactured with premium steel and advanced heat treatment to maintain a runout precision within 0.005mm/0.008mm.
Ensures rigid and secure gripping of the tool under high-speed and heavy-duty CNC machining.Features a fully ground surface and robust hardness, guaranteeing durability and reliable repeatability.
Crafted from high-quality spring steel with excellent flexibility, tensile strength, and wear resistance.
Excellent damping capabilities absorb vibration during high-speed cutting, improving workpiece surface quality. Product Description

Our precision Tool Holders serve as the critical interface between your machine spindle and cutting tools, engineered to deliver maximum rigidity, accuracy, and productivity in the most demanding machining environments. Manufactured from high-grade alloy steel with advanced heat treatment and precision grinding, these holders ensure minimal runout, superior damping, and extended tool life. Whether for high-speed milling, heavy-duty turning, or precision drilling, our comprehensive range provides the perfect, reliable solution for your CNC machining center, lathe, or mill-turn equipment.Product advantages1.Ultimate Rigidity & Stability:Constructed from premium through-hardened alloy steel, our tool holders provide exceptional resistance to bending and torsional vibration. This ensures stable machining processes, superior surface finish, and the ability to handle aggressive cutting parameters.2.Exceptional Precision & Low Runout:Each holder undergoes precision grinding to achieve extremely low TIR (Total Indicator Runout), typically within 0.003mm (3µm) at the nose. This guarantees optimal tool concentricity, improved part accuracy, and prolonged tool life.3.Full Compatibility with Industry Standards:We offer a complete range compatible with all major spindle interfaces, including BT, CAT (V-Flange), HSK, CAPTO, and VDI. Available for various tool holding systems: ER collet chucks, end mill holders, side lock (Weldon) holders, hydraulic chucks, and shrink fit holders.4.Advanced Design for Optimal Performance:Features such as high-precision ground tapers (MAS BT / DIN CAT), balanced designs for high-speed operation (G2.5 grade or better), and corrosion-resistant nickel plating ensure reliable performance, quick tool changes, and long service life.5.Enhanced Process Security:The secure and accurate clamping mechanism eliminates tool slippage and pull-out during heavy cuts and interrupted machining, protecting both your tools and expensive machine spindles.6.Versatility for All Applications:Designed for a wide array of operations including high-speed machining (HSM), heavy roughing, finishing, drilling, and tapping. Suitable for machining centers, lathes, milling machines, and multitasking machines.
