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.

Why choose a bi-metal blade?

Bi-metal blades combine a flexible body with a hard cutting edge, which makes them shatterproof and gives them superior cutting power. They are the blade to grab when the work flexes the blade or when you want a blade that resists breaking mid cut.

Will these 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.

What is the difference between the H340 and H345 blades?

The H340 is the bi-metal blade, shatterproof with flexibility, and the H345 is the all hard blade, built for highly accurate cutting and high wear resistance. Pick the bi-metal for tough flexible cuts and the all hard for fine, accurate work.

Can I use these blades for fine metal work?

Yes. The 32TPI pitch is the finest in the range, so it suits thin sheet and fine trimming where a coarse blade would snag. It gives a cleaner edge on thin material and is the blade to reach for when accuracy matters on a small cut.
