Compatible with the IJ-875 &IJ-872 jointer4 rows of carbide bladesCompatible with our IJ-875 and IJ-872 Jointer, this spiral cutter head will last longer than standard straight knife cutters. You can rotate the cutting teeth so the jointer stays sharp.
Carbide cutting teeth are more durable than straight steel bladesEach square tooth has 4 cutting edges. If you wear out an edge, you can rotate the cutting square 90° for a new edgeSpiral head offers a smoother cut if correctly set upNo need to worry about leaving streaks on boards if a cutting tooth gets chipped - just rotate it and continue to produce quality resultsSmall cutting teeth produce narrower chips than straight-knife cutters, so your dust collector won’t get cloggedFaster and easier to set up: the cutter head comes with each square indexed in its place (with a straight 3-knife cutter, you must adjust the height)Much quieter than a 3-knife head. The tiny blade squares are staggered and don’t hit the material at the same timeCovered by a 1-year warranty
