You can drill holes in stones, bricks, granite or even marble, but you need a hard drill bit made of hard metal to complete it. Masonry drill bits are specially designed to process stones and can easily drill through these hard surfaces. Masonry drills usually use tungsten carbide tips, which can withstand drilling on hard stone surfaces and have large grooves that can pull out a large amount of material when drilling to prevent debris from clogging the drill. Some drill bits even use diamond-encrusted blades to cut this material. They are available in a variety of sizes to meet different needs.
This guide will introduce the factors to consider when buying the best masonry drill bit and review some of the best drill bits for drilling through concrete.
For projects that need to drill through concrete or other stone surfaces, it is important to use a drill that is strong and sharp enough to drill through particularly hard and dense materials. Read on to learn about materials, bit types, bit compatibility, and other key factors to consider when choosing a masonry bit.
Masonry drill bits need to be hard enough to withstand the harsh test of drilling through concrete. With this in mind, most masonry drill bits have steel shafts with cutting tips made of tungsten carbide. Tungsten carbide is much harder than steel and can wear through stones without quickly becoming dull. Some drill bits use diamond particles, which are welded to the cutting edge to bite through hard surfaces such as marble and granite.
Some drill bits have coatings to improve their performance. Black oxide coatings are more durable than high-speed steel because they can prevent rust and corrosion. The tungsten carbide coating enhances the strength of the drill bit, enabling it to drill through stone and concrete.
When buying any type of drill, it is important to consider its compatibility with the drill. Not all drill bits are suitable for all drill bits. A ½-inch size drill will fit drills with a shank diameter of up to ½ inch, while a ⅜ inch size drill will only fit drills with a shank diameter of up to ⅜ inch. Masonry drills are also available in SDS+ and hexagonal shank styles. Hexagon shank drill bits are suitable for standard cordless or corded drill chucks, while SDS+ drill bits are only suitable for electric hammer drill chucks.
Masonry drill bits are available in a variety of sizes to meet a wide range of needs. The smallest masonry bit is about 3/16 inch in diameter, and the larger bit peaks at ½ inch size. The size of the hole saw bit can be up to 4 inches or more.
When buying and using masonry drill bits, there are several important guidelines to follow to ensure success.
The following products take the above considerations into consideration, and select some top masonry drills according to their grades. These drill bits come from some of the most well-known tool manufacturers in the industry.
Bosch’s masonry drill bit is one of the best drill bits on the market, with a design for fast drilling through masonry and a cemented carbide drill bit that can withstand the rigorous test of percussion drills. The wide four-slot design enables these drills to quickly remove material when drilling, preventing the drill from being crimped by debris.
The tip fixes the drill bit in the masonry structure to achieve more precise drilling. With its carbide tip, the drill bit will withstand the hammering impact of these powerful drill bits. The set has five pieces, including 3/16-inch, ⅜-inch and ½-inch drill bits, and two 2¼-inch drill bits of different lengths. The sturdy casing keeps the drill bit organized until needed. The bit set is compatible with electric hammer drills.
This set of Owl Tools includes multiple drill bits and is inexpensive. The drill bit includes a tip that helps to activate the blade in the hard masonry while ensuring accurate placement of the hole. The carbide-coated tip increases durability, while the powerful groove on the shaft allows quick drilling through concrete cinder blocks, tiles and cement.
With its wide range of sizes, this kit can meet most masonry drilling needs; the diameter of the drill bit ranges from ⅛ inch to ½ inch. A convenient carrying case keeps the drill bit in order for easy storage or transportation. The bit has a hexagonal shank end, making it compatible with most standard cordless and corded drills.
Drilling holes in stone requires testing the drill bit, which usually wears them out quickly. Although these Makita drill bits are more expensive than other masonry drill bit sets, they have thicker tungsten carbide tips that do not wear out quickly and have a longer life than most drill bits.
Each drill bit contains a wide spiral groove, which can pass evenly and quickly through stones, concrete and bricks. It comes with five drill bits, ranging in size from 3/16 inch to ½ inch. The drill bit handle is used in conjunction with an electric hammer drill with at least a ⅞ inch chuck size. The included plastic drill box provides convenient storage.
Spending money on special masonry drill bits that are not commonly used may not be the most economical way to expand the drill bit series. This set provides a good choice because the shape of the drill bits and the carbide tip make them suitable not only for drilling through concrete and stone, but also for metal, wood and even ceramic tiles, ensuring that they will not accumulate dust waiting for the next masonry Work.
Each drill bit in the kit has a tungsten carbide head that is hard enough to withstand hard materials. In addition, they have sharp edges and a large U-shaped groove, which makes them faster than standard drills. The hexagonal shank adds versatility, making it compatible with standard drill bits and impact drivers. The kit includes five drill bits: 5/32 inch, 3/16 inch, 1/4 inch, 5/16 inch and ⅜ inch
With their carbide coating and radical design, these drill bits are a good choice for drilling through concrete, bricks and even glass. The spear-shaped tip easily penetrates masonry, allowing precise drilling in concrete, tiles, marble and even granite. The cemented carbide coating increases durability and ensures that these drill bits can withstand repeated use.
The wide U-shaped groove around the shaft can quickly remove dust, prevent clogging around the drill bit and speed up the drilling speed. The kit includes five different sizes of drill bits, including ¼-inch, 5/16-inch, ⅜-inch, and ½-inch bits, and a convenient plastic storage box. The triangular shank of the drill bit is compatible with standard cordless and corded drill shanks.
These Workpro drill bits have ultra-wide grooves, which can quickly discharge debris during work, thereby achieving ultra-fast drilling. The crown-shaped end can provide higher stability and higher accuracy when drilling, and the carbide tip makes the kit have a longer life.
Small grooves on the shank help prevent slipping when drilling at high torque levels. The kit includes eight drill bit sizes ranging from ¼ inch to ½ inch. A durable hard plastic suitcase keeps the drill bit organized and easy to transport to the job site. The handle has an SDS Plus groove, making it compatible with SDS+ hammer drills.
This seven-piece drill bit is made of cemented carbide bits, which can withstand the rigorous test of electric hammer drills. The kit adopts Bosch’s four-edged design, which can quickly discharge dirt and debris when drilling, thereby speeding up the processing speed. The pointed tip allows the drill to be easily centered while creating a smoother hole.
When the drill bit is worn, the wear marks on the tip of the tool can let the user know. The size of the seven bits in this group ranges from 3/16 inch to 1/2 inch. SDS+ shank fits most electric hammer drills. When on the toolbox or workbench, the durable hard plastic storage box keeps the drill bit organized and protected.
Cutting hard surfaces, such as granite, marble and other dense stones, requires the hardness of diamonds. A diamond bit is welded to the tip of this core bit, enabling it to grind some of the hardest materials. The fuselage is made of durable steel and can withstand a variety of uses.
These drill bits are available in a variety of sizes, ranging from less than ¾ inches to 4 inches in diameter. They should be used with angle grinders (or adapters if using standard drill bits). In order to prolong the service life of the drill bit and prevent overheating, please spray the masonry surface with water before and during the use of the drill bit.
If you have questions about how to successfully drill through concrete, please read on for answers to some of the most common questions.
First drill the pilot hole by positioning the tip in the desired position and starting the drill at a low speed setting. Once you have established a ⅛ inch hole, remove the drill bit, blow the dust out of the hole, and continue drilling at a moderate speed while applying steady pressure to the drill bit until the desired depth is reached.
You can use a normal drill bit to drill through the concrete, but it will be slower than using an electric hammer drill.
Grinding drill bits manually with a file or bench grinder is a complicated process. To grind drills yourself, you need a machine specially designed for grinding drills.
