CARBIDE TIPPED HEAVY-DUTY MITER/DOUBLE MITER 12 INCH DIA x 100T 4+1, -5 DEG, 1 INCH BORE CIRCULAR SAW BLADECut gap-free miters, every time. These blades are designed especially for glass-smooth compound miter cuts in moldings and picture frame stock for use in a miter box and single/double miter machines. This style blade is the perfect choice for picture frame and millwork shops. Unlike thinner miter blades which have a tendency to flex and warp, throwing off the miter joint, our blades are stiffer and provide clean burr-free cuts in wood. Special grind, minimal run-out and tight side clearances all combine to yield perfect "gap-free" miters every time!
