SUS420J2 52HRC equivalent special small-diameter ball end mill achieves an astonishing lifespan more than twice that of conventional tools.
The MPX coating developed for SUS420J2 hardened steel, along with an optimized tool design, offers more than double the lifespan compared to conventional options!
Ball end mills for finishing high-hardness materials! They provide long tool life and stable machining accuracy.
● Adopted a spiral ball shape to improve the cutting performance of the cutting edge. ● Adopted a cutting edge shape to enhance the chipping resistance of the cutting edge. ● When the outer peripheral edge contacts the workpiece surface, chatter vibrations occur due to increased cutting load, affecting tool life and workpiece surface quality. By adopting a stronger back taper shape, this impact can be mitigated.
Challenging new realms of solid tools! "INNOVATION in your hands."
【Overview】 "2KMB" is an essential tool for processing precision parts and molds. The feature of 2KMB is its ability to achieve long life with a variety of high-hardness materials. It accommodates various high-hardness materials, including alloy tool steel, stainless steel, and high-speed steel. Additionally, the new coating MEGACOAT HARD EX and its unique shape enable a glossy and beautiful finished surface. 【Features】 ● Achieves long life with the new PVD coating MEGACOAT HARD EX ● Unique blade shape that draws an S for a high-quality finished surface and excellent wear resistance ● Large core thickness ensures high tool rigidity
For cutting processing of precision parts and molds. Achieving "long lifespan" and "beautiful finish" with new coatings and unique shapes.
In the fall of 2021, our company launched the "2KMB," a solid ball end mill for high-hardness material processing (micro-machining), marking our entry into the micro-machining market. In August 2022, a lineup of R2.5 to 3.0 was added, allowing us to better meet a wider range of needs. Our goal is to improve productivity in the micro-machining of precision molds and small parts using various high-hardness materials. Developers will explain the strengths that the 2KMB demonstrates in a world where extremely precise machining is required.

I tried machining a tapered hole on the end face of a super hard round bar using a ball end mill. Machine used: machining center.
A φ2, 90° tapered hole was drilled into the end face of a round bar made of ultra-fine particle super hard alloy, Sumitomo A1 (HRA91.4). This time, a diamond-coated tool from Union Tool was used. Compared to the finish of an electroplated tool, the surface is finished quite beautifully.
