Niagara Cutter MBZ215M Carbide Die/Mold End Mill, AlTiN Coated, 2 Flutes, Ball End, 1mm Cutting Length, 1mm Cutting Diameter Reviews
Niagara Cutter MBZ215M Carbide Die/Mold End Mill, AlTiN Coated, 2 Flutes, Ball End, 1mm Cutting Length, 1mm Cutting Diameter Feature
- Die/mold ball nose end mills are used when creating contoured or rounded three-dimensional features and cavities
- 15-degree slow helix provides more strength than higher helix angles when cutting hardened mold and die steels and high temperature alloys
- Aluminum titanium nitride (AlTiN) coating lubricates the end mill for high-temperature stability and abrasion resistance, offering better heat resistance than TiN, TiAlN, and TiCN coatings
- Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool's ability to go deep into the workpiece and remove material
- Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures
The Niagara Cutter MBZ215M metric AlTiN-coated carbide die/mold ball nose end mill has two flutes and a 15-degree slow helix for roughing and finishing complex three-dimensional dies and molds in extremely hard materials with a Rockwell Hardness of up to 62 HRC (hardened high-speed carbon and tool steels, for example). The 15-degree slow helix adds strength to the cutting edge and is optimized for machining the very hard materials used in die and mold manufacturing.
The AlTiN coating resists heat better than TiN, TiAlN, and TiCN coatings, increasing tool life and performance. It also offers increased hardness compared to TiN and may reduce the need for lubricants based on the application. The two flutes have better chip-carrying capacity than end mills with more flutes while offering additional support when the tool goes deep into the material in applications with a high depth of cut. The carbide substrate is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. The tool’s ball nose creates contoured surfaces, where sharp corners are not required. The center-cutting design has cutting teeth at the end of the tool, so it can be fed into the workpiece like a drill bit. On smaller flute diameters (from 1 mm to 5 mm), the larger shank is blended to the smaller cutting edge with a 7-degree draft angle to minimize interference between the shank and the workpiece, allowing the tool to go further into recessed areas of the workpiece. The cutting diameter tolerance is +0.000 mm to -0.025 mm. The round shank accommodates a range of tool holders.
End mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter. If heat is not reduced effectively, the tool’s cutting edges will dull and additional material buildup can occur. The number of flutes can range from two to eight. Two-flute designs offer the most efficient chip removal, but more flutes provide a smoother finish. The shank is the end of the tool held in place by a tool holder or machine. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. Non-center-cutting end mills are for applications such as peripheral milling and finishing, but cannot make plunge cuts.
Niagara Cutter has been designing and manufacturing precision cutting tools since 1954. Specializing in end mills, cutting mills, and saws, the company is based in New York and manufactures its tools at facilities in Pennsylvania and Massachusetts. This allows the company control over production, from substrate to coating, which is essential for customers in a variety of industries, especially aerospace and automotive.
