High Power, Lightweight Portable Magnetic Drilling

In Booth S-2212, Hougen Manufacturing, Inc. (Swartz Creek, MI) has released a new model of portable magnetic drill, the power feed HMD927, which offers a major performance improvement to the mid-range line of Hougen magnetic drills. The HMD927 has the power to drill holes up to 1.625 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 of Hougen drills. The newest innovation is the mag drill pilot light. The 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 holes 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 increases 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, 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 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 Hougen’s magnetic drill accessories. The HMD927 weighs just 43 lb (19.5 kg), measures 22.8125 in H x 8.75 in W x 14.6875 in L and provides drilling capacities from 7/16 in to 1.625 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.

The company has also released a completely redesigned HMD904 portable magnetic drill. This new upgraded model includes major improvements and features. The HMD904, with its powerful performance, lightweight size, small footprint and hole capacity is the most popular model in the line of Hougen magnetic drills. A number of new features and innovations not seen on previous models have been incorporated into this redesign. The newest innovation is the mag drill LED pilot light that is built into the base of the magnet and allows the operator to more efficiently and quickly line up the pilot with the holes center location in low light or no light conditions. Powering the drill is a proprietary motor with a new design to the aluminum casing to improve durability. 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, hole accuracy and quicker use of accessories such as drill chucks and tapping attachments.

The HMD904 has many additional features that make the drill easier to use: a more robust housing design with an ergonomic carrying handle, a spot to hold the hex wrench, reversible feed handles 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 carrying case. For additional productivity, a swivel base magnet and coolant bottle version of the drill is also available. The HMD904 weighs just 28.9 lb (13.1 kg), measures 19.625 in H x 7.75 in W x 11.625 in L (499 mm x 197 mm x 295 mm) and provides drilling capacities from 7/16 in up to 1.5 in (12 mm to 38 mm) diameter and 2 in (50 mm) depth of cut. The drill has an electrical rating of 9A and a 450 rpm motor.

For safety, both the HMD904 and the HMD927 mag drills incorporate exclusive features to insure a safe work environment — including a no-adjustment safety switch, which 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. Both the HMD904 and the HMD927 are made in the U.S.
