Long Neck Ball End Mill for Hardened Steel

NS TOOL Co., Ltd. offers the MRBH230, a two-flute long neck ball end mill with Mugen Coating Premium specifically designed for hardened steel.

"The unique cutting edge features a stronger spiral shape than conventional tools, providing excellent chipping resistance, less chattering due to increased cutting load and improved finishing surface by back taper peripheral edge," said a company spokesperson.

The spokesperson continued: "When you need high accuracy finishing, you have to consider each operation, from roughing to the final finish pass. The substrate will be very important. MRBH230 looks like a common standard ball end mill. However, you can see the difference in accuracy when using the correct tool size for an application. A slight difference in the amount of overhang often significantly changes the rigidity of the tool. Proper tool selection is essential for high-precision machining. For machining of molds in particular, the tool list also indicates the actual effective length depending on inclined angle of workpiece."

The company offers 334 tool sizes for applications ranging from roughing to finishing.
