Product Description

√ Valve Seat Cutting Bit Holder

√ Valve Seat Insert

Forged from high-strength alloy steel, it is rigid and resistant to deformation. It is precisely matched with the Serdi standard interface, making it easy to install and highly accurate in positioning. It can adapt to valve seat cutting requirements of multiple angles such as 30°/45°/60°/75°, and its load-bearing capacity and durability are comparable to the original.

Made from high-quality tungsten carbide, this cutting edge is sharp, wear-resistant, and chip-resistant, suitable for machining various valve seat materials such as cast iron, alloy steel, and stainless steel. The replaceable blade design allows for quick replacement after single-angle or multi-angle wear, reducing operating costs. Cutting efficiency and lifespan are comparable to Serdi original blades and are compatible with Serdi and Newen original tool holders. Blade specifications are based on Serdi and Newen catalogs, ensuring extremely high precision. All blades undergo angle measurement with professional instruments before leaving the factory to guarantee accuracy.

√ High-precision Tool Holder

Machined by precision grinding, with radial runout ≤0.005mm, and tightly connected to the tool holder and spindle, effectively avoiding cutting vibration and ensuring the coaxiality and surface finish of the valve seat. Compatible with various Serdi Newen valve seat machining machines, boring machines, etc., and matched with our valve seat series products, it is widely used in the precision boring, reaming, and shaping of valve seats for internal combustion engines such as automotive gasoline/diesel engines, construction machinery, marine power, and agricultural equipment. It can complete multiple processes such as valve seat sealing surface cutting, chamfering, and countersinking, meeting the batch and customized processing needs of repair shops, engine remanufacturing companies, and parts processing plants.

√ Precision Pilot

√ Precision Reamer

Made of high-quality tungsten carbide, and processed by quenching and precision grinding, with a dimensional accuracy of ±0.002mm, it features precise positioning and high coaxiality, effectively ensuring the sealing fit between the valve seat and the valve. It is suitable for machining and positioning valve seats with different orifice diameters and is compatible with all Serdi series mandrel specifications.

This carbide reamer is made of high-quality solid carbide, processed by precision grinding and quenching. With sharp and smooth cutting edges, its hardness reaches above HRC65, featuring excellent wear resistance and impact resistance. Focused on high-precision hole machining, it can precisely ream various materials such as steel, aluminum alloy, stainless steel and cast iron. The processed hole precision reaches H7-H8 grade, and the surface finish is Ra≤0.8μm, greatly improving workpiece assembly accuracy and stability. 

Specification

This valve seat tool set is strictly designed and manufactured according to Serdi official catalog standards, fully compatible with Serdi series valve seat machining equipment (direct replacement, no machine modification required). We provide a one-stop complete set including valve seat tool holder, high-precision shank, special valve seat inserts and precision mandrel, with factory-level machining accuracy, stable cutting performance and obvious price advantage compared with original Serdi tools. It is an ideal cost-effective solution for precision boring, reaming and forming machining of engine valve seats in automotive, engineering machinery, ship power and other fields, greatly reducing enterprise procurement and operation costs.
