Big Drill Bits

The hammering action of a hammer drill will chisel away the concrete while the rotary action drills the hole. Similarly, veterinarians review our pet articles, lawyers review our legal articles, and other experts review articles based on their specific areas of expertise. There are two dimensions that need to be determined: the diameter of the bit required and the length of the bit.  In fact, about two-thirds of actual drilling time is spent hitting and trying to get through rebar. Concrete brick, or mortar are tough materials and concrete is harder and tougher to get through than normal cement, mortar or brick. I have briefly explained the differences between brick, cement, mortar and concrete. Most bricks that we see everyday are made mostly from clay, which is the pressed into blocks, and heated up in a kiln to make them hard.

They are used for building mainly and are easy broken as you may already know. Depending on how cement is actually made it has different uses such as under water constructions, for setting posts and many other uses. Sure, you can drill a hole or two in a concrete block with a regular drill and a masonry bit, but you’ll want to step it up a notch if you have a whole bunch of holes to drill into 50-year-old concrete.

If there is no force on the chuck, the discs are separated by a clutch and the pounding action stops. Many hammer drills can be used as a regular drill by switching off the hammering action.

Drilling holes in concrete has never been easier. I grew up with drills that were supposedly dual purpose you could switch them …INTRODUCING The New TE YX Hammer Drill Bit – Big Masonry Drill Bits


These bits would fit straight into a ratchet drill, and the ratchet drill would be used against a strong arm, for pressure to push the drill into the work piece.

One example is cylindrical wire wheels meant to be pushed into a pipe of some sort to clean the inside of the pipe, but some ordinary, but mostly rather large, wood drills have threaded shanks as well.

Threaded drill bits may be held in drills meant to reach into very tight spaces, and threaded countersink cutters are widely used (along with finely adjustable depth stops) to create holes which put a matching rivet directly flush with the surface.

Archived from the original on 2007-09-18. Start off drilling slowly, creating a shallow hole that will act as a guide when drilling the rest of the hole. Let the tool do the work- apply even pressure throughout. Hold the drill level during the entire drilling process. This article is meant to serve only as a basic explanation of concrete fasteners. Suitable for drilling concrete, stone and brick. Double-fluted shank for efficient waste removal. Masonry bit for use with impact or percussion drills. Concrete dust can be hazardous to breathe in, so make sure you wear a mask during this process. You can also extract the dust by using a damp cotton swab to wipe it out. Having too many in a small area greatly increases the chance of cracks. How do you drill a medium size hole into cinder block, all the way through the other side? What’s the easiest way to drill into a concrete ceiling? Can a hole be drilled in hydraulic cement for a lead anchor? Then, drill a shallow pilot hole using a low speed or short bursts. Screw into the mortar between blocks, if possible, as it is much easier to drill into mortar than concrete block. For any application where the screw will be subjected to weight (such as a bench, handrail or shelves) heavy-duty lead anchors should be driven with a hammer after the holes are drilled and then screws driven into the anchors.

If your anchor turns as you screw into it, cut a plastic anchor into strips. Do not bear down on the drill with all your strength. You can put up shelves, hang paintings, install lights, and do much more quickly and safely. Read the user manual and learn how to use it. Hold the drill with one hand like a gun, with your index finger on the “trigger”. Place your drill on the mark and drill briefly, using a low speed (if your machine has speed control) or in short bursts (if it doesn’t).

Place the drill in the pilot hole, keeping it exactly perpendicular to the concrete surface. Gradually increase the drill speed and force if necessary, but make sure the drill is stable and under your control at all times. Sometimes, a drill does not go as expected. Take care not to drive the nail too deep to easily remove. The max and min size screw is indicated. Drills bits with a diameter larger than 13 mm normally have a reduced diameter shank so that they can be inserted into a 13 or 16 mm chuck.

If you hold both handles in the “6 o’clock” position i.e. This will almost certainly happen if it is a high power drill without a safety slip chuck. When drilling, back out of the hole every so often to remove material. This is essential with flat wood bits which don’t have flutes (the helical slots on the sides). Lubricate the bit and workpiece with light machine oil if drilling steel. Don’t hold small workpieces while drilling. When drilling heavy or fixed objects, this is unnecessary. A lip and spur (brad point) wood bit is best for drilling plastic. Apply light pressure, just sufficient for the swarf to start spiraling away from the workpiece. Lastly when drilling metal, take it easy as you break through to the other side. Ideally place a block of wood under the workpiece to stop the metal pushing outwards as it thins before breakthrough (this is easier to do if you are using a drill press).

A demagnetizing tool is a useful gadget for removing magnetism from drill bits, screwdrivers and other tools. Spade bits are available to 40 mm diameter and similarly for auger bits. Forstner bit is probably the best option. However you can buy small diamond core bits, similar to the diamond coated bits used to drill glass. I stand much benefited by going through this article and am now in a position to use a drill effectively. I have learnt the art of drilling and that too in just one sitting all by myself. I have learnt the art of drilling and that too in just one sitting all by myself. Please choose which areas of our service you consent to our doing so. If not just use a piece of tape to measure the depth as shown in the picture below. Mark the spot on the wall where you need to drill. I actually keep an old screwdriver in my toolbox just for using on jobs like this. You can use it to mark the hole and also to grind out a bit of the concrete, to help give you somewhere to place the point of the drill bit.

Now place the drill bit on the marked spot and start drilling at a low speed. Go easy at the beginning until the hole starts and then you can apply more pressure. Once you get the hole started, then turn up the speed and let the drill do the work. Check out this video below to see a practical demonstration. So as you can see from the video above, if you have the right tools for the job, then drilling through concrete is a great deal easier than you may have thought.

It depends a lot on what you are drilling the concrete for, as to what size of hole you need to drill, and what type of anchor or plug you are going to put into it.

The bottom line is however, that as long as you have a good hammer drill, a decent quality masonry bit, then all it needs is a little know how and you can get the job done quickly and successfully.

Hopefully that has given you enough information, on how to drill through masonry of various types. and while keyless chucks are handy on a regular drill, they often don’t have the holding power needed for drilling into masonry. The pounding power of a rotary hammer is measured in pounds of impact energy. These drills will also bore into concrete, but slowly. Good for drilling holes in light masonry, and concrete up to 1 in. There’s no reason to burn up both time and bits by drilling deeper holes than you need to. In fact, too much pressure will slow the drilling process and put a whole lot of unnecessary wear and tear on the motor gears.

Also, smaller bits don’t skate around as much as larger bits do, which is helpful when you need a hole in a precise spot.
