Frequently Asked Questions

What does 18TPI mean and what is it for?

18TPI means 18 teeth per inch, the coarsest pitch in the Sutton guide. It is the pitch for 6 to 25mm material, such as pipe, angle iron and steel bar, where the bigger teeth clear the swarf and cut the thicker section efficiently.

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.

Why do the blades have pin hole centres?

The pin hole centres are what fit the blade to a standard hacksaw frame. The pins on the frame locate in the holes and hold the blade under tension, which keeps the blade straight and lets it cut cleanly. All Sutton blades use the 300mm pin spacing.
