1.HSS Inch 1/4 round push broach, 2.Nominal Diameter: 1/4" ~1", 3.Broach Length: 5 7/8"~10 1/4", 4.Material: M2/M35 - details see: https://www.machineto.com/hss-inch-1-4-round-push-broach-with-tin-coatings-10146855

Round Broaches are designed to generate in one-pass a precision Round hole in a previously cast, drilled or reamed round hole. These Internal Hole Broaches are ideal for precise tolerances, sizing, and finish for those applications demanding precision and finish. Broaches are furnished with variable pitch teeth and available in American Standard as well as coated. A burnishing section can be furnished.
