Lenox 1L Holesaw Arbor offers great performance. It fits hole saws from 9L to 19L. The shank is hex - shaped, with a size of 1/2 inch and larger. This arbor is made of hardened carbon steel, providing added durability across the cross - section. The split - point pilot drill enables it to start on contact, ensuring faster penetration and less wandering. It features simple plug ejection, thanks to the sliding pins on the 7L arbor design. Also, it's very user - friendly as the power groove shank allows it to be used in the LENOX® Uni - Drive Quick Change System without the need for tool changes (3L, 5L, 6L and 7L).

Using the Lenox 1L Holesaw Arbor is easy. First, make sure the hole saw you're using is in the 9L - 19L range. Attach the arbor to your drill. When starting a hole, the split - point pilot drill will start on contact, so just press gently and let it do its job. Once you've drilled the hole, the sliding pins on the 7L arbor will help you easily eject the plug. When using it with the LENOX® Uni - Drive Quick Change System, there's no need to change tools. As for maintenance, keep it clean after each use. Wipe off any dust or debris. Store it in a dry place to prevent rusting. Avoid using excessive force that could damage the hardened carbon steel structure. With proper use and care, this arbor will serve you well for a long time.
