New Industrial Four-speed Mag Drill
Hougen Manufacturing, Inc. has released a new model of portable magnetic drill, the HMD934, offering increased power and performance for holemaking in serve industrial applications.
The HMD934 was developed to give metal fabricators more strength and torque to drill large deep holes in steel, and is able to drill holes up to 4” deep and up to 3-1/16” in diameter.
the HMD934 has a number of features and innovations that provide convenience and ease of use for the operator, the manufacturer said. The mag drill pilot light is a LED light built into the base of the magnet that allows the operator to more efficiently and quickly line up the pilot with the holes center location in all lighting conditions. A guide rail feed system maximizes cutter stability and rigidity. Powering the drill is a proprietary high torque two speed Hougen motor. The two speeds along with interchangeable gears gives the drill four speeds which help maximize tool life and increases torque when using large diameter cutters. Magnet holding power is increased with the use of impactor points and the two stage magnet which further increases magnetic holding power by 30 percent when the drill motor is turned on. This also saves energy and increases magnet life.
The HMD934 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 robust housing design with ergonomic carrying handles and a ring on the back of the magnet for quickly attaching the safety chain. There is an adjustable depth pilot and positive slug ejection which ensures the slug is ejected when the feed handles are reversed. An optional pressurized coolant system is available to provide additional coolant volume and better flow for deep hole drilling.
Portable and compact in size, the HMD934 weighs 72 lbs., measures 26-1/4"H x 10"W x 17-3/4"L and provides drilling capacities from 5/8" up to 3-1/16" (16-77mm) diameter and 4" (100mm) depth of cut using Hougen’s “12,000-Series” annular cutters. The drill has an electrical rating of 13.5A and provides 70/120/200/332 RPMs.
For safety the HMD934 incorporates 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. The HMD934 is made in U.S.
