So are they Universal? Well, No.
Drill bits are not universal because different tips are used to perform different projects. Besides, there is no tool that can efficiently cover the whole field but some can be said to somehow be universal.
For instance, there are High-Speed Steel ones designed for wood and metal and other hard materials, those of which are carbide tipped.
That said, universal tips like hex shank tips are perfect for drilling holes in a wide range of materials including concrete, plastic and wood.
However, some may not be ideal for drilling holes into fragile materials like glass and ceramics, which explains why “universal” may be a strong word to use.
Can You Use Any Drill Bit in Your Drill?
One thing you need to know is that there are some classed as norma, standard. However, you need to be aware of the shank size and ensure it fits your cordless drill.
Avoid buying larger tips that may not fit into the shank. Common chuck sizes include:
- ½-inch (13 millimeters) – Accepts tips with shafts measuring ½-inch and are suitable for heavy-duty applications.
- 3/8-inch (10 millimeters) – Accepts tips up to 3/8-inch shaft and is ideal for light-duty tasks.
Are Drill Bits Interchangeable?
Yes. They are interchangeable with different shanks if they fit.
For instance, if you have been using a ½-inch tip with your old machine, and end up buying a new one, you can use the same tip if the shaft size permits or if it is universal.
Additionally, there is no need to stick to the same manufacturer for either home improvement or professional applications.
For example, a Dewalt machine comes with tips that are fitted for that specific equipment. So, if you will need them in different sizes that were not included in your package, you can buy the right size from somewhere else and use it as long as the shaft size permits.
Similarly, Dewalt tips can be used to create holes with different drills provided that they are the same size.
How Do You Tell the Difference Between Drill Bits?
It can be difficult to distinguish between wood and metal tips because the two are very similar looks wise. However, it’s crucial to know how to tell the difference because we use them for different applications or projects.
Wood Drill Bits
These feature a lip and a spar. The spar ensures the tip is centered while drilling to prevent it from wobbling as this can damage other sections of the wood.
The lip acts like a chisel and cuts through the wood to create holes with smooth finishes. Wood bits can be black or silver however they can also come in other colors.
These can also be used to make holes in other materials like plastic, especially when fitted on a hand drill. However, they’re also not universal.
Metal Drill Bits
These tips have an angular tip and may have gold, copper or black finish. However, they do not rely on color as a differentiating point as it may vary.
What Are the Different Types of Drill Bits?
There are three types of drill bits:
Wood Drill Bits
You need the correct drill bits set for wood for perfect woodworking which include:
- Brad-point
- Auger
- Wood spade or paddle
Metal Drill Bits
Metal bits are also referred to as twist bits and they are commonly used for an electric drill. They include:
- Masonry drill
- Universal
Special Drill Bits
These types of drill bits perform specific types of drilling, usually in professional applications and home improvement. They include:
- Tile
- Glass
- Saw
- Screwdriver
