Set and kerf

The set is the sideways angle given to the teeth. It makes the cut wider than the band body, so the body and the tooth edges clear the cut instead of rubbing. A wider set suits work where the cut tends to close on the blade. We do not publish a kerf or set width figure for this blade: ask us if your job depends on one.

About this blade

Specifications come from the manufacturer's published information. If the job is unusual, talk to us before you order.

Reading the TPI

TPI is the number of teeth per inch along the band. A single figure, such as 14, is a constant pitch: the teeth are evenly spaced. Two figures, such as 2/3, are a variable pitch: the spacing changes along the band between 2 and 3 teeth per inch, which breaks up vibration and lets one blade cover a wider spread of section sizes.

Read the pitch against the thickness of metal the teeth pass through. The published rule is to keep between 6 and 24 teeth in the cut: too few and each tooth takes too big a bite, too many and the gullets clog. Thick sections need a coarse pitch, thin sections and tube walls a fine one.

For tube, profiles and bundles the pitch depends on the wall thickness too. The blade finder works it out from your section and names the chart it used.

Frequently asked questions

What does M42 mean on a bandsaw blade?

M42 is a cobalt high speed steel grade used for the tooth edge of bi-metal blades. It holds its hardness at the temperatures generated when cutting steel, so the edge outlasts carbon steel teeth on ferrous work.

When should I step up from M42 to M51?

M51 carries more tungsten and suits harder, more abrasive work such as tempered steels, larger solid sections and some exotic alloys. If M42 blades are wearing quickly on tough ferrous material rather than failing from fatigue, M51 is the usual next step.

How do I measure the blade length my machine needs?

Check the machine's specification plate or manual first: most state the blade length in millimetres. If neither survives, measure an old blade by marking the weld, rolling the loop along a straight line on the floor and measuring the distance covered. The measuring guide walks through both methods.

Can I order a length outside the range shown?

Use the enquiry link under the length field on this page and tell us the length and the machine. We will come back to you.

Full measuring instructions are in our guide, How to measure a bandsaw blade length, and on the custom lengths page.
