Clymer 7MM Throating Reamers are made from high-quality M-7 High-Speed Steel for durability and longevity.
Designed for professional gunsmiths, they come with a guarantee and are available in Rougher and Finish Reamer types for efficiency in chamber cutting.
These reamers have specific features like 5 left-hand spiral flutes, a 2½° throat angle, and are .002" larger than bullet diameter, ideal for increasing freebore by lengthening the throat.
