Reinforced to cut stronger, last longer and resists tooth strippage. High speed steel teeth resist breaking and offer extended life. Thick backing plate with holes for drive pins resists damage due to high torque.
Lenox AA1 series arbor adaptor is ideal for 1 length, 4 length and 5 length hole saw arbors. Adaptor is made of hardened carbon steel for strength through the cross-section and is ideal for all drilling applications.
