These end mills have a long shank and a cutting edge that curves around the top of the ball end, allowing them to reach into pockets to create undercuts. Made of solid carbide, they are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid …
When the end slope was changed from 3° to 14.5° (at 2.3 m/s air injection, 7 Hz vibration), the proportion of the 4–8 and 2–4 mm particles separated to the heavy part decreased from 90% to 9%, and 95% to 20%, respectively, while the bulk density increased from 0.89 g/cm 3 to 1.12 g/cm 3, and 0.87 g/cm 3 to 1.08 g/cm 3, respectively.

A conventional semi-autogenous grinding (SAG) and ball mill grinding circuit is proposed. The conceptual design targets a grind size P 80 of 65μm, utilizing a SAG size of 6.7 m diameter by 2.8 m (EGL) long and a ball mill size of 4.5 m by 7m (EGL) long. The SAG mill is closed-in with a pebble circuit where pebbles are crushed prior to being ...
Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.
Industry-leading machining often requires high-performance tools that have more than one capability. With a Kennametal indexable end mill, you have the milling potential of a conventional solid carbide end mill with the flexibility of an indexable insert. This allows you to complete a vast range of applications, such as face and contour milling, ramping, slotting and helical interpolation.

Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turn-key ...

Excellent performance for a wide range of workpiece materials such as carbon steel, alloy steel and hardened steel. Solid Carbide. MP2SDB. Ball Nose Type. Short. Excellent chipping resistance with a strong S curve cutting edge.
A 45° corner chamfer improves cutting edge strength, so these end mills last longer than standard square end mills when milling hard material; however they do not create as sharp of a corner. Variable spacing between the flutes reduces vibration, allowing them to provide fast cuts, smooth finishes, and long tool life.
