Solid Carbide End Mills
An End Mill is a type of milling cutter designed to be held by the shank on one end in order for it to cut with the opposite end. The advantage to an End Mill is that, unlike any other type of milling cutter, it is capable of cutting on the periphery, the face or the end of the cutter.
At Okay, we offer only high quality& high precision carbide end mills, the standard number of flutes can range from two to four. The fewer flutes offer the most efficient chip removal, but a higher amount of flutes provide a smoother finish. The End Mill’s helix angle is also important. Most Okay carbide end mills have a 45-degree helix angle because it is mostly for (high-angle) helix End Mills.
Specific projects require special styles of End Mills. Ball Nose End Mills are best for machining round bottom holes and complex contoured surfaces. Square Nose End Mills have square ends and are best for slotting, profiling, and roughing. Corner Radius End Mills have a square end with rounded corners on the cutting edges to reduce chipping.
Cutter material is an important consideration when selecting an end mill. Carbide End Mills can run at higher speeds than high-speed or cobalt steel, it is also more resistant to wear and can be used at high cutting temperatures.
An End Mill’s end cut type can either be center cutting or non-center cutting. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. All of our Carbide End Mills are center cutting.
Okay end mills offer a variety of coatings. Some end mills are uncoated, while others are coated with finishes to enhance performance. Most finishes extend the life of the End Mill and allow higher cutting speeds and feed rates.
Okay End Mill Coatings:
TiN (Titanium Nitride) For 50HRC End Mill Coating
A special multilayer coating for edge retention and corrosion resistance when used on a wide range of materials including iron based, hardened steels, and stainless steels. Typically TiN is used in applications with lower cutting speeds than TiCN and ALTiN but often improves the tool's lifetime by a factor of three or more.
ALTiN (Aluminum Titanium Nitride) For HRC55 and 60HRC End Mill Coating
This is a high performance coating for milling, tapping and drilling in stainless steels, carbon steels, alloy steels, and cast iron. This coating is extremely heat resistant and can be used with or without coolant. It is exceptional in difficult to machine materials where adhesive wear is particularly high and can be run at much higher speeds and feeds than all other coatings.
We highly appreciate your kind enquiry about our end mills!
