The smallest size drill bit typically available is a size 80 drill bit, which has a diameter of 0.0135 inches. This is the smallest size that is generally used for drilling a range of materials, but other sizes may be available, such as size 97, which has a diameter of 0.
0095 inches. Micro-drill bits, which are even smaller, are sometimes used for very precise drilling operations. These can be purchased in sizes as small as 0.003 inches in diameter, although such sizes are not commonly used.
What are the sizes of masonry drill bits?
Masonry drill bits come in a wide range of sizes that are commonly measured in millimeters (mm). The most common sizes range between 3mm and 16mm, although some masonry drill bits go up to as large as 25mm.
Generally, the smaller the bit diameter, the shorter it will be, while larger bits can be quite long. Depending on the type of material you are drilling, you may need a wider range of sizes and sizes that are larger than 25mm.
For harder materials like concrete and brick, a masonry drill bit typically ranges between 4mm and 25mm, although sizes up to 32mm may be used for very hard masonry material. For softer materials like cinder blocks and tile, the range of sizes commonly used are between 4mm and 16mm.
When choosing a masonry drill bit, it is important to consider the application as well as the overall hardness of the material. For example, metal-drilling masonry drill bits usually range from 3mm to 8mm and require precise drilling.
Are concrete and masonry drill bits the same?
No, concrete and masonry drill bits are not the same. Concrete drill bits are specifically designed with a carbide tip that is capable of drilling through concrete or other cement-based materials. This type of drill bit requires a higher speed and greater pressure to effectively chip away at the material.
Masonry drill bits, on the other hand, are designed specifically for use in drilling through tile, stone, stucco, and other natural materials. The carbide tip is designed for optimal performance and wear resistance, allowing for better grip and lower pressure.
The shape of the tip and wing-like blades allows the bit to break cuts in the material quickly and efficiently.
How can I tell if a drill bit is for masonry?
A good way to tell if a drill bit is for masonry is to look at the tip of the bit. Masonry drill bits have a carbide tip, which looks like a tiny, tipped cylinder with a rounded bottom. This tip can cut through masonry materials such as concrete, brick, stone, and ceramic tile.
In comparison, drill bits for wood have a spade-shaped tip, with wider, flatter edges, while drill bits for metal have a sharp tip with multiple cutting edges. Additionally, masonry drill bits may be labeled as such, often with “masonry” in the name or inscribed onto the bit itself.
Finally, you can confirm that you are using a masonry drill bit by placing it in a drill and beginning to drill into a brick or stone wall.
Why can’t I drill into brick?
Drilling into brick requires specialized tools and techniques, and can be labor-intensive and time-consuming. Drilling into brick also requires a thorough knowledge of the material and use of the appropriate drill bit.
When using the wrong drill bit, drilling into brick can lead to cracking or chipping of the brick, weaker brick structures, and ultimately, more damage to the brick than originally intended. Furthermore, because brick is a harder material than wood and other materials, it requires more pressure and more time to drill into it.
For example, when drilling into brick, the drill bit must be changed frequently to keep the temperature of the bit low or risk damaging the brick. When improperly done, drilling into brick can also lead to serious personal injury due to flying debris, making it a task that is best left to professionals.
Do I need a masonry drill bit for concrete?
Yes, you will need a masonry drill bit if you are drilling into concrete. Masonry drill bits are specifically designed to work with hard materials such as concrete, brick, and stone, whereas standard drill bits are more suitable for drilling into softer materials such as wood and metal.
Masonry drill bits have a carbide tip and a fluted shape that allows the bit to cut through hard materials more effectively. Additionally, masonry bits typically have a shorter length than standard bits, which helps to reduce the chances of the bit breaking when being used on harder surfaces such as concrete.
For the best results when drilling through concrete, select a masonry bit that is specifically designed for concrete.
How do you tell the difference between a concrete drill bit?
A concrete drill bit is typically identified by its shape, size, and material. Drill bits used for concrete typically have a wide and fluted tip, which helps disperse the dust created by the drilling.
They are usually made with hardened steel or a cobalt or carbide alloy, which helps it hold its sharpness while drilling into hard material like concrete. In terms of size, concrete drill bits can range from 1/4-inch to 1 5/8-inch in diameter, and are usually between 3 inches and 10 inches in length.
Knowing the size you need is important for drilling into concrete effectively. The length of the bit should be the same or slightly longer than the depth of the hole you plan to drill. If a bit is too short, it could lack the strength and energy to break up the concrete material, which could lead to a broken bit.

Are titanium drill bits better than HSS?
Titanium drill bits are often considered to be better than high-speed steel (HSS) drill bits for many reasons. Titanium drill bits are made from a harder metal alloy than HSS so they are better at enduring wear and tear and resisting corrosion.
They are commonly used in tougher materials, such as metal, since they stand up to the pressure better than HSS. Additionally, they have an intense heat resistance which helps make drilling more precise.
This makes them a preferred choice when precise drilling is required, particularly in automotive or aerospace engineering. Finally, titanium drill bits are more expensive than HSS drill bits and are often used when precise drilling is required and the job is too difficult or expensive for an HSS bit.
Does titanium require a special drill bit?
Yes, titanium does require a special drill bit. When drilling through titanium, you will need to use a cobalt or carbide bit to prevent any breakage from occurring. Titanium can be extremely difficult to drill into due to its hardened properties, and so special drill bits are necessary to ensure an easier and more successful drilling process.
If a regular bit is used, it will likely cause more damage than good, and the drill bit could break during the process. For an easier drilling experience and to ensure the drill bit is strong enough to handle the metal, a cobalt or carbide bit is recommended.
What drill bits stay sharp the longest?
The type of drill bit that stays sharp the longest depends on your specific drilling needs, as certain types are better suited for certain materials than others. Generally, the more expensive high-speed steel and cobalt drill bits remain sharp the longest, while titanium-coated and ceramic drill bits may eventually become dull over time.
High-speed drill bits are the typical choice for general use, as they stay sharp in most materials, are extremely durable, and are notably less expensive than other types. For use when drilling into harder materials, like stainless steel, the heat-resistant cobalt drill bits will stay the sharpest the longest.
Finally, for softer materials, such as particle board or plywood, titanium-coated or ceramic drill bits should be used to ensure a longer lasting sharpness.
Is cobalt stronger than titanium?
Comparing the strength of cobalt and titanium is not so straightforward, as the strength of each metal depends on factors such as hardness, toughness, yield strength, modulus of elasticity and ductility.
Cobalt is known to be a hard, tough and highly corrosion-resistant metal, while titanium is known to have approximately double the strength-to-weight ratio of steel, making it lighter and yet stronger.
In terms of hardness, titanium has a Vickers hardness of 170-310 HV, while cobalt has a Vickers hardness of 500-610 HV. This makes cobalt significantly harder than titanium. When it comes to toughness, cobalt has an ultimate strength of 1100-1300 MPa, while titanium has an ultimate strength of 900-1200 MPa.
This means that cobalt is both harder and tougher than titanium.
When it comes to yield strength, cobalt has a yield strength of approximately 1000-1200 MPa, while titanium has a yield strength of 800-1000 MPa – again making cobalt tougher than titanium. On the other hand, titanium has a higher modulus of elasticity (stiffness) than cobalt, indicating that it may be better than cobalt for applications requiring stiffer parts.
In terms of ductility, cobalt has a greater amount of ductility than titanium. This suggests that cobalt could be better for applications that require something to bend before it breaks.
In conclusion, cobalt is generally considered to be stronger than titanium, although it is best to evaluate the two metals on an application-specific basis.
Is carbide better than cobalt?
The answer to this question is that it depends on your particular needs and preferences. Carbide is harder and more durable than cobalt, which makes it a great choice for heavier-duty applications, such as woodworking and metalworking.
However, cobalt is generally much easier to sharpen and can produce a finer edge in lighter-duty applications, including general-purpose applications like kitchen knives. When it comes to cost, cobalt is usually more expensive than carbide, but this difference can vary depending on the supplier you purchase from.
Ultimately, the choice between carbide and cobalt should be made after careful consideration of the tools’ intended uses.
