Hougen Manufacturing (Flint, MI) is now incoporating its patented swivel-base, drill-to-magnet coupling design into the model HMD925S (S-designates swivel base) power-feed model drill that features heavy-duty hole-making capability. The unit?s base coupling creates both a pivot axis for up to a 1-1/8 in arc of side-to-side motion and a straight-line axis of up to 1-3/8 in of front-to-back movement. These additional axes allow operators to fine-tune the drill position and precisely locate hole center points after the magnetic base has been engaged. Final adjustments are easily made, even when drilling in horizontal or upside-down positions.
The HMD925S uses Hougen?s Rotabroach® annular cutting tool system to produce holes from 7/16 in to 1-1/4 in (12 mm to 32 mm) diameter through materials up to 2 in thick using the power-feed option, or 1-1/2 in (38mm) diameter in manual-feed mode. The HMD925S weighs 40 lb for excellent portability and ease of use, making the Hougen drill lighter than power feed models of comparable hole making capacity. It measures 17-1/8 in H x 10-13/16 in W x 11-3/16 in L.
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 increased productivity, long tool life and lower tooling costs, with excellent hole quality in both dimensional and finish aspects. The feed motor, gearing and drive system are enclosed in the drill housing to maintain a compact profile.
It has a heavy-duty 120V, 50/60Hz at 8A and 960W electrical system, featuring a 7.2A motor delivering a high-torque 450 rpm. A 230V model is also available. The magnetic base of the HMD925S measures 3-1/8 in W x 6-9/16 in L and develops 1240 lb of dead-lift strength on 1 in thick plate and 965 lb on 3/8 in thick plate.
All of the operational controls of the HMD925S, including motor on/off and magnetic engagement, are located on the feed-handle side of the unit, providing good ergonomics and ease-of-use. The control panel has a safety switch indicator light, linked to the motion detector switch in the base of the magnet, that visually alerts users to the possibility of non-secure magnetic operation.
The power-feed activation switch is positioned in the center of the feed-handle hub, a simple lift of the latch-type handle engages the system, pushing it in halts the feed. This design, unlike other units that use the feed handles as the power feed switch, is instrumental in preventing accidental engagement of the power feed system when the drill is being used in the manual feed mode.
The HMD925S package is complete with a safety chain, hex wrench, cutting fluid, and operator?s manual. Slick-Stik soft tube lubricant is available for inverted or horizontal drilling applications to help safeguard cutting edges and materials.
