What is the purpose of the EDM oiling hole?

The EDM oiling hole is a small, precisely drilled hole that directs extra oil from the lifter body directly to the camshaft lobe. This helps to keep the lobe well-lubricated, reducing friction and wear, which is especially important for solid lifters.

Why is tool steel used for this lifter?

Tool steel is chosen because it is lighter than standard steel, which can be beneficial in high-RPM engine applications. It also offers good strength and wear resistance, making it a solid material for engine components like lifters.

Does this lifter come with any hardware?

This product includes the tool steel solid lifter itself. Any necessary installation hardware, such as pushrods or valve springs, would typically need to be purchased separately.

Product Details

This COMP Cams solid lifter is constructed from tool steel, a material that's lighter than standard steel, and features a .012" EDM oiling hole. This design choice is important because it helps deliver extra oil directly to the camshaft lobe, which is crucial for keeping things cool and reducing wear, especially in high-performance applications. It's built for .842" diameter Chevrolet engine applications that use cast iron camshafts.

The EDM oiling hole is a notable detail that sets this lifter apart, providing a more direct path for lubrication to the critical camshaft lobe. This can lead to improved durability and consistent performance over time. Because it's made from tool steel, it offers a good balance of strength and lighter weight compared to standard steel lifters.

This lifter is designed to fit a wide range of Chevrolet vehicles, including models like the Chevrolet Camaro, Corvette, and C1500. When you're rebuilding or working on the valvetrain of these engines, using well-made components like this solid lifter ensures you're putting in parts that can handle the demands of your build.
