What You Need To Complete The Job

Frequently Asked Questions

What does 24TPI mean and what is it for?

24TPI means 24 teeth per inch, the middle pitch in the Sutton guide. It is the pitch for 3 to 6mm material, such as conduit, heavy sheet metal and tubing, where the teeth are fine enough for a clean cut on the thinner wall but coarse enough to clear the swarf.

What is the difference between all hard and bi-metal blades?

All hard blades are hard right through, which gives accurate cutting and high wear resistance, but they are less flexible. Bi-metal blades have a flexible body with a hard edge, so they resist breaking under flex. All hard is the choice for fine, accurate straight cutting.

Will these blades fit my hacksaw frame?

Yes. All Sutton hacksaw blades have 300mm pin hole centres, which fit all standard size hacksaw frames. Check that your frame takes the standard 300mm length before ordering.

Why are the blades colour coded?

Sutton uses colour coding and clear markings so you can pick the right blade at a glance, without reading fine print on the blade. The 24TPI blade is easy to spot in the drawer, which saves time on the job.
