Circular Plain Cut-Off Tools
Circular Plain Cut-Off Tools
The selection of the proper cutoff tools is, of course, one of the most important decisions in laying out your job. Obviously, the tool must cut off the part. In addition, a properly designed tool can also chamfer the front end of the next part to the diameter you wish. In particular, this chamfer can be designed to break down the front end sufficiently to prepare for the threading operation.

Cutoff Width and a word of caution:
When using the following table to determine blade width, the following items should be considered:
- Least thickness used when cutting off into tapped holes is the lead of two and one-half threads plus .010.
- Lead thickness used when cutting off into reamed holes smaller than 1/8” diameter is .040.
- Thickness used when cutting off tubing is two thirds B as given below for corresponding diameters of stock.
- Thickness used when cutting off the drilled hole is greater than ½ the diameter of the stock.
