Lead Bullet Hardness - Tacticool Products

Pure lead is often described as "dead soft". For all practical purposes, pure lead can't be hardened. To increase the hardness, other metals are added to lead to form a lead alloy. Adding tin will make lead slightly harder, but a lot of tin must be added to significantly increase the hardness, and this has two adverse effects.

End mill helix angle selection | Blogs | CNCTimes

On an end mill with a 30 degree helix angle, 25 % of the force is axial and 75 % radial. On a 45 deg. helix angle, the forces are divided equally, 50 % radial and 50 % axial. High helix cutters have an helix angle of 60 deg. At a higher helix angle the radial forces are lower and cutting is smoother, vibrations lower.

Carbide End Mills | McMaster-Carr

Carbide Double-Chamfer End Mills. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material.

End Mill Types: - MSC Industrial Direct

Ball end mills, also known as ball nose end mills, are used for milling contoured surfaces, slotting and pocketing. A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations.

RobbJack Corporation

Choosing the proper cutting tool is very important when machining hardened metal. There are three basic designs of cutters: ball end, corner radius (bullnose) or square end (Figure 1). The first choice in hard metal machining should be the ball end mill. The ball end mill should be used for roughing operations and most finishing operations.

Peripheral Milling Styles and Appropriate RDOC. The amount a tool engages a workpiece radially during peripheral milling is dependent upon the operation being performed (Figure 2). In finishing applications, smaller amounts of material are removed from a wall, equating to about 3-5% of the cutter diameter per radial pass.
