The HMD115 is an ultra low profile, lightweight 21 lb drill with a quill feed arbor. Handles operate from either side and with handles removed, the hex head allows use of a socket wrench for ratcheting the feed. Handles lock for carrying. The arbor has a bayonet-style twist and lock tool mounting for quick cutters change outs. The HMD115 uses RotalocTM Annular Cutters. For safety, the motor switch must be continuously pressed during operation and the motor will not run without the magnet switch "ON". Rear mounted controls optimize ergonomics. Convenient carrying case and safety strap is standard.
