If your keyseat is working well, but you’d like it to last longer, coating is often a good place to start. It may not be suitable for every material, but the added lubricity and heat control that the coating provides may help to extend tool life. If your tool is already coated, it may be worth considering switching to a different coating. There may be more than one coating that is suitable for a material, and upgrading to a higher-performance coating may help extend life in applications that produce more heat.

Woodruffcutters

MITGI standard keyseat cutters come in four end finishes: square, corner radius, full radius, and 45° chamfer. Shank diameters range from 0.125 in. to 0.500 in, with overall lengths from 1.50 in. to 4.00 in. As tools become larger, they have larger cutter diameter, longer reach, larger neck diameter, thicker cutter width, and more teeth.

A standard line of full radius cutters is available in 3-days or less (the tool shown here is S218-003-FR). These tools are often used to create a U-shaped slot or to create a groove.

MITGI standard tools are designed for general-purpose use. They are an excellent choice when lead times are very short (3 days or less), or when the tool may be used in a variety of materials and applications.

MITGI standard cutting tools include a line of 45° chamfer keyseat cutters (S97-010-45 is shown here). If additional reach is needed, a modified standard may be the answer. Still available in 3-days or less, many MITGI standard tools can be ordered with additional reach for a small charge.

MITGI standard keyseats are available with a square-end finish (the tool shown here is S97-015-SQ-ALTIN). Also called keyways, key cutters, or woodruff cutters, this tool type is used in many precision manufacturing applications to add slots, cut keyseats, or cut the inside of a form.

In applications where the part is very complex, it’s for a high-volume product, or when it uses a hard-to-machine material, a custom tool may be the preferred option. Custom tools provide manufacturers with the ability to achieve specialized features, geometries designed for specific materials, and to achieve tool life or surface finish goals. Count on MITGI to provide accurate custom tools, achieve tight tolerances, and are usually available in two weeks or less.
