How Many Parts From One Length?
The cut-length yield calculator shows how many parts each mill length gives, the drop left over, and which length wastes the least.

The Same Part From Each Standard Length

How the Yield Is Figured.
Each part uses its own length plus one saw kerf. The end trim, if you square up the mill end first, comes off before the first part. Whatever is left is drop.
Yield is the length of good parts divided by the whole mill length. A part that divides evenly into one standard length can waste almost nothing, while the same part from another length can leave a long drop.
If no standard length suits your part, we can cut it to length at the mill, so the tube arrives as parts with no drop at your plant.
Parts = floor((mill length - end trim) / (part + kerf))
Drop = mill length - parts x (part + kerf)
Questions
What mill lengths does Heidtman Tubular run?
Standard bundles are 20, 24 and 40 feet. We run mill lengths from 20 to 48 feet and can cut shorter pieces to your length.
Can you cut tube to my length?
Yes. Ask for cut to length on the quote form, with the length and the tolerance you need.
What kerf should I use?
Use your own saw's kerf. A cold saw or band saw is often 1/16 to 1/8 in; an abrasive or carbide saw can be wider.
Why is my yield low?
A part a little over half or a third of the mill length leaves a long drop. Try another mill length, or a cut length from the mill.
