Ball nose cutter finish mills 64 HRC
steels and CI
Efficient indexable ball nose end mill, featuring a coated micro-grain carbide grade, will finish machine steel and chilled cast iron components up to 64 HRC at a cutting speed of Vc=240 m/min.
Hard machining and high-speed cutting are machining strategies which are largely taken for granted in mould and die production For this type of work Kennametal provides a strong and wide-ranging programme to which further highly productive tools have been added: Efficient indexable ball nose end mill for finish machining - hardened components of steel and chilled cast iron up to 64 HRC can be finish-machined with a cutting speed of Vc=240 m/min in less time and at lower cost with the combination of the optimised indexable insert ball nose end mill M270 and the new coated micro-grain grade TN2505 from Kennametal

Efficient indexable ball nose end mill is for finish machining hardened components of steel and chilled cast iron up to 64 HRC in less time and at lower cost.
Micro tooling system speeds up auto lathe changes
Quick-change tooling system for automatic lathes, featured in the "Micro Machining Tools" catalogue, has achieved time savings of up to 40% and can be used in turning and boring operations.
Modular drill can be changed in the machine
Modular high-performance drill, that can be changed while in the machine, adds value by reducing machining time and down-time in drilling operations.
Machining can take place either dry or with air cooling.
For different accuracy requirements indexable inserts which have been precision-ground on all sides and precision-ground indexable inserts with a sintered chip control geometry are available, ensuring that the best-possible solution will be achieved for the particular application.
Thanks to standardised interfaces, these tools can be used on existing toolholders (shank-type adaptors and screw type adaptors), which means they can provide universal service on different types of milling applications.
Milling instead of eroding - long and expensive eroding operations can now be carried out more effectively and more quickly by means of milling.
For this purpose Kennametal supplies two- and four-edged solid-carbide milling cutters in diameters upwards of 0.3mm in the new grade KC637M.
The grade features an ultrafine-grain substrate with a very thin and highly wera resistant TiAlN coating.
This combination increases both the hardness and the transverse rupture strength of the milling cutter, resulting in excellent tool life and short milling times when hard machining of steels with 50 to 65 HRC.
By replacing eroding with milling in the machining of small moulds and dies it is possible to achieve an additional reduction in manufacturing cost.
