The 24-piece Hassay Savage 15440 #40 Metric Assortment includes six broaches and 18 collared bushings for 36 keyway combinations and a 2 mm to 8 mm keyway range, and meets International Organization for Standardization ISO J-9 specifications. They come in a plastic case for storage and organization. The broaches and bushings are Hassay Savage style I, II, or III (as noted) and are made of M-2 high-speed steel for a balance of strength and toughness. The rake and relief angle of the teeth provide efficient broaching of mild steel.

Broaches are cutting tools that can be pushed or pulled through a component to make key, square, hex, and other hole shapes. Most broach styles have teeth that increase slightly in cutting edge size and distance from each other to the end of the tool so they complete the full cutting process in one operation: roughing, semi-finishing, and finishing. Keyway broaches are specifically designed to make keyways. Rotary broaches, also known as wobble broaches, create shapes in blind holes.

Hassay Savage manufactures broaching tools. The company, founded in 1969, is headquartered in Turners Falls, MA.
