What You Need To Complete The Job

Frequently Asked Questions

What does 32TPI mean and what is it for?

32TPI means 32 teeth per inch, the finest pitch in the Sutton guide. It is the pitch for material under 3mm, such as thin sheet metal and metal trim, where fine teeth give a clean cut without snagging the thin edge. For thicker material, use a coarser blade.

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 32TPI blade is easy to spot in the drawer, which saves time on the job.

How should I fit the blade in the frame?

Fit the pins into the blade holes with the teeth pointing forward, then tension the frame so the blade is firm. A correctly fitted blade cuts straight and true, and a loose blade wanders and wears unevenly, so check the tension before you start.
