What Is A Magnetic Drill?
A magnetic or mag drill is a boring device used on metals. The drill has four parts – the magnetic base, a motor, a drill stands, and a chuck or arbor. It is a portable drilling tool with a magnetic base. It can use used with twist drill bits, milling cutters, annular cutters, and other rotary cutters. Using the right kind of cutters, it can also be used to countersink, ream and tap threads.Magnetic drills are versatile tools used to bore holes in metal and wood. If you are working on steel girders or large pipes. Positioning a fixed magnetic drill can be cumbersome. A portable magnetic drill allows you to handle these jobs in situ. You can use it in a horizontal, vertical and bottom-up position. The portable drills allow for optimal handling and drill ensuring that the piece does not move and you get accurate results. The magnetic strength is related to steel. Usually, they are used on steel plates 3/8 inches thick. These tools are used in product design and development, construction, fabrication, and woodwork.
How to use a Magnetic power drill?
The drill transfers the rotational power generated by the motor to the arbor. The working of this drill is no different from the regular drills. The only differences are that these are magnetically fitted on to the metal piece. This helps get an accurate result on a slippery metal surface. Here is the step by step process of using the magnetic drill.
- Place the mag drill close to the material where you want to drill holes.
- Tighten the safety chain around the drill press. This prevents the tool from slipping in case the tool loses power and the tool disengages.
- Next, fit the drill bit and secure it.
- Then fill the coolant reservoir with coolant. Usually, the manufacturer recommends it.
- Align the drill bit with the marks or the pilot holes on the material.
- Switch on the magnet.
- Turn on the tools power switch.
- Begin drilling slowly into the material. Once the cutting groove has been set, apply more pressure. Hold the tool in place until the drilling is complete.
- Switch off the power and clean the drill chips from the tool. Then move on to the next hole.
How Does A Magnetic Drill Work?
The working parts of a magnetic drill are :
The Motor – on the magnetic drill is mostly a brush DC motoror a brushless motor. It may run on battery power or electricity. Battery driven magnetic drills are more popular nowadays. The drill may also have grease gearbox and oil bath gearbox motors. The gearboxes are an economical option compared to the oil bath motors. The latter cost more and have a longer life.
The Arbor – gives more control over the drill. The user has the option of using the manual or quick changing option with the cutter.
The Front Support Brackets – connect the arbor and the cutter. It also serves as a guide for drilling holes. They control the depth to which the drill cuts.
The Annual Cutter – is a hollow tool that makes various types of holes. This is because of the various groove options the tool comes with. It is used to drill holes in the workpiece.
The Electromagnet – has a soft metal core that behaves like a magnet when electricity is passed through it. The electromagnet helps the drill to be firmly attached to the material you are working on at a press of a button. This gives the user control over the tool and its boring action. This also keeps the user safe.
The Housing – protects the components from the elements and damage. Some models have plastic housing while others may have metal ones.
Pilot light – is positioned just above the cutter. It helps you see better. The improved visibility helps gain accuracy in work. The tool may or may not have it – but it is a useful feature.
Types of Magnetic Drills
All mag drills have magnetic bases that stick to the work material. There are 3 types of magnetic drills – hydraulic, electrical and pneumatic. Each of these drills has pros and cons.
Electric powered drills – are lightweight with plenty of power. They carry all the above-mentioned features and are very dependable. These mag drills come in various sizes and some have reversible motors. The only downside is – you cannot use them in wet conditions.
Pneumatic drills – use compressed air to do the job. This means you can use them in wet and flammable conditions as there are no sparks. Their downside is – they are costly.
Hydraulic drills – harness the power of a pressurized liquid. These are specialized tools mostly used underwater as the aquatic environment does not bother them.
Essential Features on a Magnetic Drill
If you are interested in investing in one of these tools then here is what to look for…
Power – is expressed in watts or amperes. There is no right value per se but consider drills above 8 amperes or 1000 watts and above.
Design & convenience of use – A good design will be compact and well-balanced. This well-balanced design will facilitate easy portability and safe use of accurate results. The unit should have carrying handles. Reversible handles lend consistency and stability to the tool. Some have removable handles that make the tool ambidextrous. The handles can be removed and fitted to the right or left side of the tool.
Appropriate size – A larger drill is not always the better drill. Consider the material you are working with, the workspace and then consider the requirements.
The weight– leads the tool stability and portability. When the tool is well-balanced it handles better while doing the job. After the job is done it is easier to move to the next site. The benchtop models weigh less than the floor models. Note the weight of the tool that you are comfortable with – they come with certain features such as a low profile and compact size.
Magnetism – A Magnetic drill should be able to attach to any surface. It offers consistency in work and stability. When used in vertical applications the strength of the magnet is particularly important. If you work in shaky or unstable environments such as a boat on undulating water this feature lends stability. The magnetism should be powerful enough to stay pressed to the point even on a vibrating surface. Magnets work differently on different models. Some activate only after the drill starts running. Acquaint yourself with the tool as there are specific models to meet your specific needs.
The cutting capacity – of magnetic drill presses differs from model to model. These drills are used to create holes in a workpiece.
The power source in portable mag drill is usually the 20V, 40V or 60V Li-ion batteries.
Safety – Check for the safety rating of the drill. It should have easy to use buttons; automatic turn-offs a control to keep you safe. Some may have overload limits and rubber over-molds. These prevent slippage of tools and other accidents.
The Price – Dissociate price with quality and performance. Do your research and sacrifice additional features for performance and quality. Your tool should be able to handle the work pressure.
Type of Model – There are floor and benchtop models of magnetic drill presses. The floor models are meant for larger projects. Correctly set up they bring you accurate results. The benchtop models are meant for smaller projects. You may use them if there is a dearth of space.
The available space – Pick a model based on the size of the work area. You can opt for a floor drill press or a benchtop drill press accordingly. Both are portable.
The accessories such as spotlights, removable handles improve the functionality of the tool. The kit may include a drill press table, laser guide, tool tray, clamps, press bits, chucks, bit sharpeners, and extensions.
The serviceability of a magnetic drill allows you to prolong its life. You should be able to replace the worn parts with ease.
