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.
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 18TPI blade is easy to spot in the drawer, which saves time on the job.
How much pressure should I apply when cutting?
Let the blade do the cutting with firm but steady pressure, and use long, even strokes. Pushing too hard deflects the blade and gives a crooked cut, while too little pressure lets the teeth rub and dull. Find the pace where the blade bites and keeps cutting.
