Since engine valve seats are usually made of high-hardness heat-resistant alloys, it is becoming more and more difficult to repair the valve seats with traditional high-speed steel valve seat reamers, and the traditional development methods are also very labor intensive.

The valve seat reamer uses high-quality hard alloy as its teeth. The cutting edge is sharp, wear-resistant, and has excellent cutting performance for valve seat materials of different hardness. Abrasive tools made of superhard material diamond or cubic boron nitride can not only quickly remove the hard carbon layer on the surface of the valve seat, but also effectively grind the reaming working surface to achieve installation accuracy. The two tools can be used together, with multiple functions, good performance, high efficiency and long life. Is currently the most ideal valve seat repair tool

The kit includes the following:

-Valve overlap angle

(1) Reamer: 47x60°/ 34x60°/ 36x45°/ 40x45° / 43x45° / 48x45°

(2) Abrasive tools: 38x45° / 42x45° / 48x45°

-Top valve chamfer

Reamer: 31 X75°/ 34x75° / 36x75° / 40x75° / 43x75° / 48x75°

-Bevel under the valve

Reamer: 32 X30°/ 34x15° / 36x75° / 40x15° / 40x15
