RotaFoam™ is a foamy spray lubricant that is sprayed onto the cutter before each hole.įor best results use the mag drills coolant system. The user applies a glob to the inside and cutting teeth. RotaMagic™Ĭoncentrated Cutting Fluid is a biodegradable coolant that is mixed with water and used with a mag drills coolant system. Number of different kinds of lubricant depending on the application. Coolant increases annular cutter tool life dramatically. Always use a safety chain especially in horizontal & overhead positions. Hougen mag drills have a built-in safety circuit that stops the motor when the drill lifts from the material. ![]() If it does shift or lift during the cut, it is very possible the cutter will break. A safety chain or strap also helps to prevent injury if the drill shifts. Obtaining optimal holding power, which can cause the drill to shift or lift during operation. Uneven surfaces or large debris buildup prevents the magnet from Make sure the drill’s magnetic base is clear of chips and debris and is securely attached to a clean surface. Situations where the magnet will have reduced holding power.Ĭ) Chips, dirt, or grease between the magnet and the materialĭ) Curved surface (Surface should be flat. For non-ferrous materials use a Vac-pad™ (HMD904 & HMD905 only) or clamp a piece a steel on top of it.Ī clean smooth surface will allow the magnet to ‘stick’ better. Material that is clean and free from coatings will offer the best surface for the magnet. Clamp another piece of steel on top or below the thinner steel for stronger adhesion. If the material is thinner, the magnet will not hold well. Mag drills must magnetize to a solid surface. From ultra low profile to large multi-speed models. Depth of Cut)Īvailable in a variety of sizes. Use this chart to determine which mag drillto use.
