Increased productivity and efficiency of cutting tools can be obtained with various types of coating processes.   We can coat all of our product offerings to the coating you require.  If we don't stock the item on our shelf coated the way you want it, we can provide it in relatively short order.  Some options include:

Titanium Nitride (TiN), Single layer
TiN has very good corrosion resistance, heat transmission and excellent wear resistance with a wide range of materials including iron based materials, hardened steels and stainless. Increased tool life can run 3 to 8 times greater with increased feeds and speeds (finished parts per hour). Longer tool life or greater feeds and speeds depend upon the application, coolant, and other conditions. This high performance coating is a great all-purpose choice for increasing tool life. TiN increases hardness and has a high oxidation temperature. This coating is bright gold in color with a surface hardness reaching 81 Rc and a .4 coefficient of friction. Titanium Nitride (TiN) is the most common PVD hard coating in use today. TiN has an excellent combination of performance properties, attractive appearance, and safety (meets FDA requirements for surgical tools and implants as well as food contact applications). Hardness; 2800 HV. Coating Thickness; 2-4 microns. Thermal Stability; 550 deg. C or 1000 deg. F.

Titanium Carbo-Nitride (TiCN), Multi layer
As with TiN, feeds and speeds can be increased and tool life can improve by as much as 800% depending on the application, coolant, and other conditions.  TiCN offers improved wear resistance to abrasive, adhesive, or difficult-to-machine materials such as, cast iron, aluminum alloys, tool steels, copper, inconel and titanium alloys.This multi-layered coating is best suited for hard work materials over 40 Rc and operations involving interrupted cuts and high shock applications. The addition of carbon adds more hardness and better surface lubricity. Coating is medium gray or bronze in color with hardness reaching 90 Rc and a .3 coefficient of friction. TiCN Coating has up to 750 Degree F thermal stability. Hardness; 3000 HV. Coating Thickness; 2-4 microns. Thermal Stability; 400 deg. C or750 deg. F.

Titanium Aluminum Nitride (TiAlN or AlTiN), Multi layer
AlTiN offers a higher surface hardness than that of TiAlN, along with different percentages of aluminum and titanium. TiAlN's improved ductility makes it an excellent choice for interrupted cutting operations. Its superior oxidation resistance provides great performance in high temperature machining. TiAlN does not exhibit edge brittleness and can be used for interrupted cuts without chipping. This popular coating is recommended for applications where heat resistance and extra hardness is required for abrasive materials.A formed layer of aluminum oxide gives this tool better life in high heat applications. This coating is primarily selected for carbide tooling where little to no coolant is being used. Coating is purple/black in color with a surface hardness in the upper 80 Rc range with a coefficient of friction less than Titanium Nitride (TiN). TiAlN coating is a high performance coating which excels at machining of abrasive and difficult-to-machine materials such as cast iron, aluminum alloys, tool steels, and nickel alloys.

Also available are multi-layer coatings that chip to the next layer instead of the tooling substrate, providing a further increase in tool life.

CVD Diamond Coating
CVD diamond coated end mills and router bits work well in profile milling, plunge cutting and slotting in a wide range of composites and non-ferrous materials.  The diamond coating also is excellent for machining graphite and copper mold electrodes and by manufacturers fabricating component parts made of hard carbon materials. CVD diamond coating can improve life by 10 - 20 times over uncoated tools and 5 -10 times over other types of coating when machining graphite, hard carbon and other abrasive materials.
CVD diamond coating works well to cut carbon fiber composites and wood composites with resin where abrasiveness and galling become problems.  One of the benefits of this diamond coating is we can offer true spiral fluted shapes versus PCD flat shapes for better cutting performance.
