Drill Bit FAQs

What is the strongest drill bit you can buy?

The strength of a drill bit primarily depends on the material from which it is made. Among the options known for their robustness: Cobalt drill bits are recognized for their exceptional hardness and resistance to heat, making them well-suited for drilling into tough materials like stainless steel.

Carbide drill bits are extremely durable and excel in drilling hard substances such as concrete, masonry, or metal.

Titanium drill bits, featuring a coating that enhances hardness and durability, prove effective across various materials, including metal and wood.

Diamond drill bits, specifically crafted for drilling into exceptionally hard materials like tile, glass, or ceramics, are renowned for their strength.

The choice of the strongest drill bit ultimately relies on the specific material you intend to drill, with options like cobalt, carbide, titanium, and diamond bits providing varying degrees of durability and longevity.

How do you tell what size a drill bit is?

Determining the size of a drill bit involves examining its markings or measuring it’s dimensions. Look for markings on the shank, which often indicate the size in inches or millimetres. 

For bits without markings, use a drill bit gauge or calliper to measure the diameter of the bit at it’s widest point. Alternatively, compare the bit visually to a set of standard drill bit sizes. 

Keep in mind that fractional and numbered sizes are common in imperial measurements, while metric bits are labelled in millimetres. 

Accurately identifying the size ensures the proper fit for screws or bolts and precise drilling in various applications.

What is the best drill bit for metal?

The best drill bit for metal depends on the type of metal you are working with. For general metal drilling, cobalt drill bits are highly effective. They are made from cobalt alloy, providing durability and heat resistance, making them suitable for drilling through tough metals like stainless steel. 

High-speed steel (HSS) drill bits for metal are another versatile option, offering good performance and durability. For specific metals like aluminium or brass, consider specialised drill bit sets designed for softer materials. 

Always match the drill bit material and type to the metal you are working with to ensure efficient and precise drilling results.

What are the 3 types of sizes of drill bits?

Drill bits are available in three main size types. First, there are fractional sizes, expressed as fractions like 1/8 inch or 3/16 inch, and commonly used in both wood and metal drilling applications. 

Second, there are numbered sizes, indicated by numbers such as #8 or #10, prevalent in imperial measurements and often associated with specific screw diameters, making them suitable for tasks involving screws. 

Lastly, there are letter sizes, designated by letters of the alphabet, such as A, B, or F, used in imperial measurements and typically employed in machine work and metal drilling. 

Understanding these size types within your drill bits sets is crucial when selecting the appropriate drill bit for specific applications and materials.

What drill bits should you use for brick?

When drilling into brick, it's essential to use the right drill bits for optimal results. Masonry drill bits are the most suitable choice for brick.

Drill bits for masonry feature a carbide or tungsten carbide tip, designed to handle the hardness of masonry materials. Additionally, the flutes on drill bits for masonry help remove debris efficiently. 

It's advisable to use a hammer drill in conjunction with your masonry drill bits set for better performance. Select the appropriate size of masonry drill bit based on the diameter of the anchor or screw you intend to use. 

Always prioritise safety by wearing protective gear, such as safety glasses, when drilling into brick.
