WOOD magazine review

Finally, carbide knives for benchtop planers

Review Summary

We all know carbide tips on saw blades and router bits outlast steel edges, but until recently you couldn’t get carbide knives for your benchtop planer. Infinity Cutting Tools’ carbide-edged knives delivered about 10 times the life of new carbon-steel knife edges on my DeWalt DW735 planer. Analyzing motor-amperage draw and observed cut quality, we judged the steel knives dull after planing 48' of particle-board (chosen for its accelerated abrasive dulling effect) in each of two tests.
The Infinity carbide knives planed 492' and 528', respectively, before dulling. A set of three single-edge Infinity knives sells for about $250. Five sets of double-edge disposable knives ($50 per set) would yield the same edge life, making the effective cost a wash. But you’ll save yourself the hassle of nine knife changes. (Resharpening the Infinity knives isn’t practical because they reference off cutterhead pins, and so their height cannot be adjusted.) At the time of testing, Infinity had carbide-tipped knives only for DeWalt’s DW735, but had plans to make them for other models. —Tested by Bob Hunter

Infinity carbide planer blades

Review Summary

Don't waste your money. I wore these out in two days building an oak stair case and all I got done were the risers. They would probably be ok for the hobbyist, but they only lasted 2 1/2 times longer than a set of dewalt blades, NOT the 10 times as advertised. For the money, I am extremely disappointed and I am not getting a good response from customer service. You would be much better off buying the dewalt double sided blades for $60.
