FAQ

Ask the ColdSawStore Doctor.

Q. What speed should I use for cutting stainless steel?

A. Stainless steel should be cut at a speed of approximately 70 SFM (surface feet per minute). When using a 12"(315mm) cold saw blade, that means the RPM should be 22-25.


Q. What number of teeth should I use for cutting solid bar stock?

A. The number of teeth should be selected carefully. When cutting solid material, you need to have three to four teeth cutting(engaged) in the material simultaneously. For a 1" bar that means you would need to have a tooth pitch of approximately .285". If your saw blade was 14"(350mm) diameter, you need to have 140-160 teeth. Too many teeth can prevent you from getting proper cutting times. Too few teeth can result in broken teeth/blades.


Q. When cutting pipes/tubes, my saw blade seems to have trouble cutting through the top and bottom, Why?

A. When the blade enters the top of the tube and exits the bottom of the tube, there are more teeth engaged in the cutting process due to the arc of contact. As the teeth pass through the walls (middle of the tube), it is easier to cut.
