Drill a hole of the size you need to guide your masonry bit in a piece of wood and then use some double sided tape to stick it to the wall. The hole in the wood keeps the bit from wandering. If, after drilling, they do not line up you could plug the hole with a wood dowel and adhesive and drill that out.
Try a good quality drill bit, designed for masonry and don't lean too hard on the drill. The drill bit should do the work, if you lean too hard on it then it can overheat and blunt off. Set it to hammer and let the drill do the work, might take a while but cheaper than an SDS.
To avoid cracking the brick, follow these steps: Always drill at least an inch away from the edges of the brick. Apply steady, even pressure rather than forcing the drill. Start with a smaller pilot hole before moving to larger bit sizes.
To keep your drill bit from slipping, start by creating a small indentation at the drilling point using a center punch. This helps guide the bit in the correct direction. Using a lower speed and applying steady, even pressure can also prevent slipping.
You can use a center punch if accuracy is critical, as starting a bit can allow a bit of drift before the bit bites. Step sizes up until the hole size you need is reached. Keep the drill square to the surface of the door to make sure your hole is usable when you're done.
A damaged drill bit can have a bend in the shank, which makes it hard for the tool to grasp the bit. Replace damaged or crooked drill bits with undamaged bits. Drill Bit Warehouse supplies high-quality drill bits at competitive prices.
Stick-slip is caused mainly by rotational friction induced along the drillstring, from the drill bit cutting the rock formation to the bottom hole assembly and drill pipe that contact the well bore.
Centre-punch the drill hole beforehand to prevent the bit from slipping. Stick masking tape over the marked area for extra grip. Switch off the percussion or hammer function on your drill and work carefully and cautiously, applying gentle pressure.
It's always best to use masonry drill bits or concrete diamond point screws. Both are designed to grind and bite into the material. A regular drill will require more force to push through the concrete or brick and all-purpose drill bits are more prone to snap under that pressure.
To keep a drill bit from wandering when drilling in metal, put the point of a center punch or nail set on the spot you want the hole, then tap it with a hammer to make a small dent in the metal. Chuck the drill bit in the drill, place the bit on the dent, and drill the hole. Watch the video above to find out more.
For best results when drilling into concrete it is recommended that you start by using a pilot hole before widening it out with the larger drill bit size you are using for your project. This will help ensure that your hole will be as straight as possible. Drill straight while applying pressure.
Faulty equipment and warped or bent drills are likely to wander and may also break. An inaccurate starting position will make drill wander inevitable. Using the wrong feed pressure and speed, or inconsistent drilling, can make drill wander more likely.
Ensure That You Are Applying the Right Amount of Pressure
Applying steady pressure through the drive bit or screwdriver helps to ensure that the tip engages fully with the screw head and cannot slip easily.
The part of the drill that holds the bit in place is called the chuck. Inside the chuck there are three jaws, which you can see when you rotate the collar, the jaws either open or close depending on which direction you are rotating the collar.
Slowly start up your drill and allow it to make a start on drilling the hole. Don't push too hard as this will heat up the bit too quickly. Once the hole is started and it can't wander off, you can start to build up the speed. Move the drill bit back and forth to clear the dust and debris out of the hole.
As mentioned earlier, drilling through tile requires a specialist drill bit – regular or even masonry bits simply won't do the job as they're not strong enough to penetrate tiles' hard surfaces. Instead, you should opt for either carbide-tipped or diamond-tipped drill bits.
