Buying Guide – What to Consider when Choosing the Best Drill Bits for Brass
If you’re working on a project that requires you to drill through brass material, you need high-quality drill bits.
However, there are a couple of factors to consider before you go shopping to ensure you get the right product. These include:
The first thing to consider is the kind of material the tool is made from. Generally, drill bits for brass are manufactured from two main types of materials, including HSS and cobalt steel alloy.
Units made from cobalt steel don’t break easily and are heat-resistant. They are also less prone to damage, which ensures quality drilling performance and results.
High-speed steel bits, on the other hand, are also durable but not as much as their cobalt steel counterparts. However, they offer high-speed drilling and relatively cheaper.
Another feature to look out for is the design of the shank. The shank is the part of the bit at the end that you “plugin” to the drill. Therefore, the shank design of the bit you choose should be compatible with the chuck size of the drill.
Some of the common shank designs suitable for drilling brass are straight and hex. The straight shank is the most common design as it is a perfect match for a standard drill chuck. More so, it is associated with minimal “walk” or “wander”.
When it comes to hex shanks, the design allows the bit to remain steady during drilling. This means you don’t have to worry about the bit wobbling or bending.
Also, it is worth considering if the tool is coated. This feature is critical, especially if you’re using a High-Speed Steel device.
A good coating will ensure better wear-resistance, thereby increasing the bit’s longevity. The coating will also minimize friction and protect the drill from rust and corrosion.
Generally speaking, most bits for cutting through brass feature a titanium coating. This type of coating is suitable for prolonged and repetitive tasks. Besides, titanium is rust, heat, and corrosion resistance.
The size of the bit is also equally important. Basically, the right size will depend on the hole size you would like to make.
So, if you will be making the same size holes, then we would recommend you get a bit of the same size. Also, if you’re a novice, you should consider getting bits in the standard size spec range.
But what happens if you will be making different size holes? Well, then it would be wise to invest in a set that comes with bits in various sizes.
If you take a closer look at the different metal drills available, you’ll notice that they have a distinct splint point. This point is usually at the tip of the bit.
For metals like brass, you will need a device with at least a 135-degree split point. This type of tip will ensure you don’t use a lot of force to remove the metal. Also, this tip design helps prevent the bit from “walking”.
Common Questions People Ask Concerning Drill Bits for Brass
If you’re new to drilling holes into brass material, here are some frequently asked questions just for you.
Q: Which is the best type of drill for drilling brass?
A: Generally, straight fluted bits are the most common types for drilling through brass. Unlike twist bits, they have less of a tendency to grab or dig in the material.
Q: What is the strongest drill bit for brass?
A: Any bit from cobalt steel alloy material is best for drilling brass. Compared to HSS bits, it boasts much faster cutting and extra-long life.
Q: Is brass easy to cut?
A: Yes, as long as you’ve got a zero-rake drill bit or straight fluted drill bits. This is because brass is good at grabbing the sharp edge on the bits.
Q: Is brass harder than steel?
A: No. it’s not as hard or strong as steel. However, it is stronger and harder than copper.
