Quantum leap in ball milling
of stainless steel

CrazyMill Cool, a solid carbide end mill cutter with through-tool cooling in the diameter range of 0.3 to 8 mm (.0118” to .315”, fractional inches available), deserves its crazy name. Contour, copy and side milling are its strengths. In its double function as a roughing and finishing cutter CrazyMill Cool promises high efficiency, long tool life and a much better surface quality.

Various factors contribute to this:

• Micro-grain carbide
• Cutting geometry
• High-performance coating
• Through-tool cooling channels

First, the raw material, a newly developed micro-grain carbide, which meets the high requirements in terms of hardness and strength. The sturdy tungsten carbide shaft allows stable and vibration-free milling. The highest degree of precision and surface quality are achieved because of this.

What is also significant is the tool design with a cutting geometry that is developed specifically - but not only - towards the machining (for example on micro milling machine) of stainless steels, where the milling tool performs at its best. A strong cutting wedge, radial relief and precise edge preparation are responsible for the high degree of cutting edge quality and stability.
Due to its highly smooth running, it will work with no oscillation and vibration. The extended cutting depths facilitate machining on the radius and on the cylindrical part, and make CrazyMill Cool Ball Z2 into a versatile tool.

The specially developed high-performance coating eXedur RIP also makes an important contribution to the tool life. It is wear-resistant and heat-resistant and, thanks to an extremely low friction coefficient and a reduced affinity to steel, there is no material buildup on the cutting edges. Furthermore, it prevents chips from jamming in the flutes. The result is long tool life.

However, the essence of innovation is embodied in the three to five cooling channels which run through the shaft of the small milling tool and exit on the tool cone (milling tool with 3, 4, 6, 10 and 12 mm (.118”, .157”, .236”, .394”, .472”) shaft). They ensure that the coolant jet flows along the tool diameter up to the cutting edges. The result is constant and efficient cooling of the cutting edges, and hence the highest cutting speeds and maximum performance ap. In addition, targeted flushing of the chips is guaranteed. Because of this the highest surface quality is reached.

Mikron Tool also offers CrazyMill Cool Ball with two teeth in customer-specific executions:

• Milling tools for hardened steel: Standardized up to 50 HRC, upon request up to 55 HRC
• Milling tools with varying diameters, lengths and teeth to the standard milling program / sizes
