Great Power-To-Weight Drilling in Steel Fabrication

Hougen Manufacturing, Inc. (Swartz Creek, MI) offers the new power feed HMD927 portable magnetic drill, a major performance improvement to their mid-range line of magnetic drills. The HMD927 has the power to drill holes up to 1-5/8 in (41 mm) diameter and offers great power-to-weight ratio by giving steel fabricators more strength and torque while still maintaining the small lightweight footprint. The HMD927 has a number of new features and innovations not seen on previous models, the newest being the mag drill pilot light. This LED light is built into the base of the magnet and allows the operator to more efficiently and quickly line up the pilot with the hole’s center location in low light or no light conditions.

Powering the drill is a proprietary two-speed motor. The two speeds help maximize tool life and increase torque when using larger diameter cutters. The addition of a two-stage magnet increases magnetic holding power by 30 percent when the drill motor is turned on. This saves energy and increases magnet life. A new arbor system utilizes a 5/8 in slot drive for more rigidity, improved hole accuracy and quicker use of accessories, such as drill chucks and tapping attachments. The power feed HMD927 has many additional features that make the drill easier to use: an integrated coolant bottle which is conveniently located and does not add to the width of the drill, a more robust housing design with an ergonomic carrying handle, a spot to hold the hex wrench, and a D-ring on the back of the magnet for quickly attaching the safety chain. The drill also includes positive slug ejection, and a swivel base magnet is also available.

Power feed mode is engaged with a hub in the center of the feed handles. The new drill incorporates solid-state circuitry that monitors and adjusts the self-feed action to continuously maintain optimum drilling performance throughout the entire length of cut. This helps to provide predictable productivity, long tool life and lower tooling costs, and excellent hole quality. The drill can also be used in a manual feed mode to utilize many of the company’s magnetic drill accessories. The HMD927 weighs just 43 lb (19.5 kg), measures 22-13/16 in H x 8-3/4 in W x 14-11/16 in L and provides drilling capacities from 7/16 in to 1-5/8 in (12 mm to 41 mm) diameter and 2 in (50 mm) depth of cut. The drill has an electrical rating of 10A and 250/450 rpm motor.

For safety, the HMD927 incorporates exclusive features to insure a safe work environment, including a no-adjustment safety switch that shuts down the drill motor if lift of the magnetic base is detected, plus an LED indicator that monitors this sensor and alerts if the switch is not engaged. A two-stage power on switch prevents drill rotation unless the magnet has first been engaged, and, in the case of a power interruption, safety circuitry will keep the drill motor off after power is restored until the start button is manually depressed. The HMD927 is made in U.S.
