It’s important to ensure the bit you choose has exactly the same size as the hole you are going to make. Going for a bit that is a little bit larger than the hole you wish to create is also fine.
In most instances, you’ll need a drill bit of standard length, but like we mentioned, there are longer bits if you need something longer.
Regardless of the of the type drill bit you choose, the golden rule here is to ensure that you pick a drill bit that is made of a high-quality and durable material, which is coated with carbide, diamond powder or titanium carbon nitride.
You need to examine the drill bit shank and ensure it’ll be grasped perfectly by the chuck of your drill. However, choosing a drill bit that’s compatible with your drill does not necessarily mean that you have to buy bits of the same brand. No!
When it comes to length, there are standard lengths, but there also long masonry drill bits that range from 300 to 400 mm.
The good news is that they rarely overheat and are highly durable. You can also use them to drill holes in timber is you need to.
If you do all this, you will be able to pick the right masonry drill bit every time you visit a drill bit store. Check out our drill bits for brick work or our products page for various tools and building supplies.
While some are meant for wood, others are specially designed for glass, metals, and masonry projects. Therefore, you want to ensure that the bit you pick is meant for masonry.
When selecting a drill bit, you have to consider the material it’s made of. There are masonry drills bits made of low carbon steel. These drill bits are cheap and can be used to drill soft surfaces.
BTA stands for Boring and Trepanning Association, and is also sometimes referred to as STS (single tube system) drilling, as it uses one single drill tube for the BTA tool, compared to other processes such as ejector drilling, which use two.
Cheap bits are usually made of substandard material and have a history of overheating and shattering when subjected to pressure. Buying them is a waste of your hard earned money, not to mention that they can ruin or delay your project.
BTA drilling tool heads are threaded or mounted onto long drill tubes, and use multiple cutting surfaces on a single tool to remove chips efficiently, exhausting them using high-pressure coolant through holes in the tool head, then out the drill tube and through the machining spindle. BTA tooling is available in brazed or inserted carbide configurations.
Consider the type of job you want to do; ensure the bit you choose is compatible with your drill; refer to your pilot chart to know the bit size and length needed; ensure you go for masonry drill bits and avoid the cheap ones.
Deep hole drilling machines that are designed to perform BTA and related processes are complex systems of high-precision components, designed and built for extremely deep holes and strict tolerances. View a machine diagram to learn about BTA drilling machines.
This is another important question that you should ask yourself. You should choose a drill bit that is compatible with your drill type.
The choice of drill bit largely depends on the project at hand. If you’ll be drilling small holes into light concrete or artificial stones, you can go for any masonry drill bit.
BTA drilling tools are chosen and integrated into the deep hole drilling system to achieve the highest tolerance standards possible.
If you go for a drill bit made of HSS, however, make sure it’s coated with carbide, diamond powder, or even titanium carbon nitride. This helps make it tough and good for masonry. The coating also helps reduce corrosion and wear.
BTA deep hole drilling is the ideal process for a range of larger deep hole drilled depths and diameters. BTA drilling, and secondary processes, are capable of drilling extreme depth-to-diameter ratio holes while achieving strict tolerances.
Choosing a drill bit that matches your project’s needs can be confusing and time-consuming because of the diverse drill types available. It’s much more complicated than you might think.
BTA drilling is a deep hole drilling process that uses a specialized drilling tool on a long drill tube to produce deep holes in metal, from holes with a diameter of 20 mm [0.80 in] and larger, up to depth-to-diameter ratios of 400:1. BTA drilling is the most effective method of drilling deep holes, as it is a cleaner, more reliable and capable process than conventional twist drills, and can achieve larger diameters and higher feed rates than the alternative gundrilling.
You should, however, avoid bits made of substandard material regardless of the quality of concrete you’ll be drilling. They’ll overheat quickly and do a shoddy job.
This will make your job easy and smooth. It’ll also help ensure that your drill will never be damaged by discordant drill bits.
Some drill bits are made of high-speed steel (HSS). These bits are a bit more expensive than those made of low carbon steel.
Yes, it’s good to consider the price when buying drilling bits, but that does not mean that you should go for cheap bits.
BTA drilling can achieve drill feed rates of typically 5-7 times faster than gundrilling at the same diameter, due to the tool design, more efficient chip exhaust, and machine design and power. BTA drilling machines introduce coolant around the tool head, and evacuate chips through the drill and machine spindle, compared to gundrilling, where coolant is introduced internally and chips exit through an external groove. BTA drilling is effective in holes from 20 – 200 mm [0.80 – 8.00 in], a greater size range than gundrilling.
In this piece, we are going to discuss tips that will help you pick drill bits that match your project needs. The tips will also help you avoid the mistakes that most buyers make when selecting masonry drill bits.
These drill bits are effective in penetrating stones, concrete block, solid concrete, and other hard and soft materials found in the construction world.
You can even carry your drill to the store to try the bits before you buy them. This will help ensure you don’t make any mistakes.
If you’re dealing with hard concrete and natural stones, ordinary drill bits are not for you. Go for drill bits that have tungsten carbide or durum tips. They are usually stronger, more efficient, and penetrate hard surfaces better and faster than the typical drill bits.
