Innovative End Mills for Mold Making

Modern day mold making processes require innovative cutting tool technologies capable of delivering the highest degree of precision, flexibility and efficiency. With its latest line of endmills, NS Tool Company, Ltd. (Tokyo, Japan) equips manufacturers with capabilities for boosting productivity and maximizing output in high-performance hard milling.

“NS Tool specializes in very high-precision, small-diameter tools,” said Darrell Johnson, the product manager of milling consumables at distributor Single Source Technologies (SST; Auburn Hills, MI). “Their intense focus on the tiniest detail in creating their product translates into cutting tools that perform consistently. The fine details of quality are so precise that one must magnify the cutting edge thousands of times to see how flawless each cutting surface is.”

End mills from NS Tool feature a variety of coatings and flute designs, offering a solution for any modern mold making challenge. Many of them have the patented Mugen premium coating, which features a hardness of 3,600 HV for longer and more stable tool life in the machining of hardened steel (48 HRc to 65 HRc) applications. Mugen premium coating is widely known for its excellent heat resistance, making it ideal for dry, high-speed-cutting operations.

Although originally designed to cut hardened steels, Mugen premium coating has proven to provide excellent wear resistance to machine steels in the lower hardness range. Tools with this coating are designed to deliver superior levels of accuracy and finish. Combining exceptional attention to quality with advanced coating technology equips the Mugen premium coating with outstanding characteristics. These high-precision, small-diameter tools can consistently create the tiniest details for excellent finishing capability.

MSBH230
The MSBH230 ball end mill features a two-flute, 30 deg helix design with Mugen premium coating. This tool is capable of producing superior surface finishes in hardened materials ranging from 48 HRc to 65 HRc. Its unique cutting-edge design reduces chatter and increases strength to eliminate possibility of chipping.

MRBH230
The MRBH230 long-neck ball endmill also has Mugen premium coating, and it is ideal for machining rib features in hardened materials ranging from 48 HRc to 65 HRc. Similar to the MSBH230, this model features a unique two-flute, 30 deg helix design that reduces chatter and increase cutting-edge strength to eliminate possibility of chipping.

MSBH345H
The MSB345H is a three-flute ball-nose endmill. Its spiral shape, coupled with unequal flute spacing, reduces chatter and yields stable cutting at increased feedrates. The additional flute enables increased productivity without sacrificing finish. Mugen premium coating supplies the wear resistance and toughness to machine steels and other materials with hardness up to 65 HRc.

MRBTNH345
The MRBTNH345 is a three-flute, long-neck ball-nose endmill. The additional flute enables increased productivity without sacrificing finish. With unequal flute spacing and spiral design, chatter is greatly reduced while stable cutting at increased feed rates is achieved. Mugen premium coating provides the wear resistance and toughness to machine steels and other materials with hardness up to 65 HRc.

MSXH440R
The variable helix angles and pitched flute design of the MSXH440R micro-grain solid-carbide corner radius endmill has the ability to suppress chatter for stable milling conditions in a variety of applications. The 40 deg and 42 deg helix angles of this Mugen-coated tool deliver excellent performance in alloy steels, stainless steels, titanium and other heat-resistant materials.

MSZ345
The MSZ345 is a Mugen-coated square endmill with Z-axis plunging capability. Its ability to center cut, drill and side mill in the same tool makes the MSZ345 an ideal solution for opening up pockets. The tool has a three-flute, 45 deg helix design with chip-breaker in the end that provides efficient cutting in steels, stainless steels and pre-hardened steels.

These endmills yield superior performance, excellent finishing capability, durability, longevity and high performance in hard-milling applications.
