Blade tension is the difference between a cut that tracks and one that wanders, and it is a property of the frame rather than the blade. A frame that will not hold tension lets the blade flex sideways in the cut, and the saw drifts off the line however carefully it is started. Tension is set by the wing nut and checked by the sound the blade makes when it is flicked.
Frame size sets what can be cut. A full size 300mm frame takes a standard blade and cuts section. A junior frame at 240mm is smaller in every dimension, which lets it work in a position a full frame cannot enter but limits the depth of cut. Frame depth also decides how far from the edge a cut can be started before the frame fouls.
Teeth per inch follows the material thickness rather than its hardness. At least three teeth have to be in contact at any moment, so thin sheet needs a fine blade at 24tpi and thick section can take a coarser one without the teeth straddling the material. Blade length is fixed by the frame, so the frame decides what blades can be bought for it.
The blade is the consumable and the frame is not. Bi-metal blades combine a hard edge with a flexible back, so they cut longer and do not snap when the frame is flexed. Packs of 2, 10 and boxes of 50 reflect how they are actually used. Send the material to 07754288583 on WhatsApp.
