Infinity Super General Saw Blade — and the Amazon Alternative

Infinity Cutting Tools sells direct through infinitytools.com, so the Super General is not something you add to an Amazon cart. Their blades are well regarded and ordering from them is straightforward. This page covers what that class of blade is for, and the nearest thing that ships from Amazon.

Sixty teeth, and what they buy

Every tooth that passes through the wood takes a smaller bite than it would if there were fewer of them. More teeth means a finer surface and a slower feed.

At 60 teeth on a 10 in blade, you are into crosscut and sheet-goods territory. Crosscut hardwood and the end grain comes off the saw with a surface you could finish directly. Cut veneered ply or melamine and the top face stays chip-free, because each tooth severs a small amount of veneer rather than levering a chunk of it.

That last point is the common reason people buy a blade like this: melamine chipping is the most visible defect in flat-pack style work and it is almost entirely a blade problem.

Thin kerf, and the trade

The .100 in plate on this blade is thinner than a standard full kerf. Less material removed means less power needed, which is why thin kerf blades are the usual recommendation for contractor saws and any saw under about 2 HP.

The cost is stiffness. A thinner plate can deflect under side load, so in thick stock, or if you feed with any lateral pressure, the cut can wander a fraction. For sheet goods and crosscuts — what this blade is for — that is rarely an issue.

Do not rip with it

Sixty small gullets cannot clear the volume of chips a rip cut produces. The waste packs, friction builds, the blade heats and you get burn marks and a stalled motor.

Keep a 24- or 40-tooth blade for ripping. The two-blade shop — a 40-tooth general blade and a 60- or 80-tooth crosscut blade — covers essentially everything a table saw is asked to do.
