![]() ![]() HSS annular cutter, you can use a small mag drill with lower power. “This dictates the power (wattage/HP) that will be required. “Mag drills should be selected according to the maximum hole diameter that is going to be drilled and the type of cutter being used,” said McDonald. It is best to pick a drill unit that is rated to cut the size of hole your application requires.īut, choosing a mag drill based on rated HP alone often can be confusing and misleading, said Londrigan. The size of the hole being drilled is another key variable because it will determine how much horsepower is required. In a large, open fabrication facility where height is not an issue, a larger two-speed mag drill might be a better overall choice,” said Londrigan. “If the application is in small or confined spaces, a lightweight, low-profile drill would be a perfect choice. If you are working overhead, you would also want a drill that is lightweight,” said McDonald.īut this again, depends on the diameter of the hole and type of cutter being used. “If you are in a very tight area with low height, you must choose the drill that fits into the area, but this can also be difficult depending on the size of the hole being drilled. Space and physical limitations must be considered. ![]() The work environment also should be taken into account when you are selecting a drill. Predictable work times on contract and serial work is possible because of the FEIN KBM 80 auto’s repeatable and consistent drilling times. Most manufacturers offer both single- and multiple-speed machines.” ![]() This is where variable speed plays an important role. “If someone is using HSS, carbide cutters, and twist drills, they will need a machine with more than one speed. “The type of material and cutter choice also have an effect on the speed requirements,” said McDonald. These applications require a machine with more than one speed. However, a machine used in a shop might also be called in to service for drilling, reaming, countersinking, and tapping. In structural steel applications a single-speed machine typically is satisfactory. The choice between single and multiple speeds mainly depends on the application. “This increases tool life for the cutter, reduces the wear and tear on the motor, and also decreases the amount of physical work performed by the fabricator.” “When you are drilling larger holes, having more speeds allows the operator to get the cutter closer to the correct RPM for the hole diameter and material,” said Greg Londrigan, marketing coordinator for Hougen Mfg. and smaller, there is no real advantage in having more than one speed. For drilling smaller-diameter holes, for example, those 1-1/4 in. Most small, lightweight mag drills have a single speed and the larger, more powerful drills have two or more speeds. “If you are drilling and tapping large-diameter holes in-house, you will need a more sophisticated drill, possibly with two speeds and electronic speed control.” Our tools deliver virtually burr free dimensionally accurate hole formation,, at an impressive speed.“If you are outside, drilling small-diameter holes in structural steel, you may only require a small, lightweight, single-speed tool,” explained McDonald. Perfect interaction between the magnetic base drill, core bits and accessories: everything is ideally coordinated for drilling in steel, stainless steel or aluminum. Thanks to their innovative design, the user has an excellent view of the drilling location. The KBC, KBU and KBA series models additionally feature a magnetic force display. The high magnetic holding force ensures that the machine stays firmly in place, thus ensuring maximum safety for users. The FEIN high-performance motor guarantees fast work progress over the long term. Maximum quality, first-class materials and the best possible material processing ensure maximum machine service life. Ever since we invented the very first electromagnetic drilling machine in 1909, we have continued to contribute to the development of magnetic base drills and core bits. Its extra long stroke enable the longest drill bits to be used, even for twist drilling and tapping. Thanks to their optimal power-to-weight ratio, the operator can also perform mobile work overhead. FEIN's magnetic base drills feature intuitive centrally-positioned control elements. We offer hand-operated magnetic base drilling systems, which are ideally suited for flexible use where space is limited, compact magnetic base drills which are as small as possible and even universal solutions which can also be used for twist drilling, tapping, reaming and countersinking. Whether the requirement is for fully automatic solutions for production work or machines with basic functionality, FEIN is the specialist in magnetic base drilling solutions.
