Time to begin our reviews.

In this section, we’ve reviewed the 6 best drill bits for plastic for sale right now, including drill bit sets.

1. Norseman Drill Bit Set

Currently, you can only buy drill bits like these that are designed specifically for use on plastics, including hard plastics such as acrylic.

Both long and short tips have a 60-degree angle, so the tip enters without damaging either. Also with the non-grab design, Norseman’s bits are easy for beginners to use, since they prevent tearing.

A different size drill bit is included in each of the 7 drill bits in this set. While there are no spare parts, we don’t mind since these bits are super durable.

A set like this is not inexpensive. The drill bits below are best for drilling into plastic regularly and need a variety of sizes.

Image

Pros

  • Creates extremely clean holes.
  • Plenty of variety in each set.
  • Durable.
  • Works well with both hard and soft plastics.

Cons

  • Slightly expensive, but worth the investment in our opinion.

Overall value rating

⭐⭐⭐⭐⭐

 

2. Task Tools Dowel Bit Set

Drilling into plastic is particularly easy with dowel bits.

They do this since they have a four-point tip that makes an easy, clean entry into the material you are drilling without requiring excessive force.

Thus, drilling into plastic can be done without cracking it, as long as you do not apply excessive force.

These bits are especially good because they have extra-wide flutes. The reason for this is that plastic chips do not break up easily, so a bit that can remove chips efficiently will prevent heat buildup.

For what you get, these bits are a pretty good value. One problem with them is that they don’t come with a great case.

Image

Pros

  • Reasonable price.
  • Makes clean holes.
  • No excess force required.
  • Dowel bit – easy to get centered exactly where you want the hole.

Cons

  • Included case isn’t the best.

Overall value rating

⭐⭐⭐⭐⭐

 

3. Neiko Titanium Step Drill Bit

You can also use a step drill bit instead of a Brad point/dowel/spur bit to make clean holes in plastic.

The steps will give you more control in drilling than a regular bit with a steep angle tip.

Due to the small tip and gradual enlargement as you drill, the hole is easier to begin exactly where you want it. Step bits (sometimes called uni bits) are much easier to work with when you are working with plastic.

Neiko’s step bit is good because its two-flute design provides a quick chip clearing process.

Despite its reasonable price, it isn’t as durable as it should be. In the future, the tip will wear down if it is continually used on hard plastics.

Image

Pros

  • Makes for extremely clean entries.
  • Good price.
  • Easy to drill where you want to drill.

Cons

  • Could be more durable.

Overall value rating

⭐⭐⭐⭐

 

4. DeWalt Brad Point Bit Set

A Brad point drill bit set for drilling into plastic that works great.

You can expect excellent quality and durability from DeWalt bits.

You would expect them to be a bit more expensive, but they’re not. This leads to less-than-perfect holes. If your material is not used in perfect conditions, you might get jagged edges at the top or bottom.

Even so, the Brad point design allows for easy drilling – the bit won’t “walk” across the surface, which is great.

Ultimately, this set is a great choice for hard or soft plastics that require quick and easy holes.

Image

Pros

  • Nice price.
  • Very durable.
  • Easy to use – won’t jump or walk.

Cons

  • Could make a cleaner hole in hard plastics.

Overall value rating

⭐⭐⭐⭐⭐

 

5. Source One Premium Drill Bit

Acrylic and plexiglass are hard plastics, so you might need a stronger bit with a traditional tip for drilling them.

Designed for clean entry into hard materials without cracking them, this option from Source One meets this need. Furthermore, it removes chips quickly, preventing excessive heat from building up.

A bit pricey, but Source One’s bit will last for a really long time. Because you can’t buy this drill bit in a set, be sure to purchase the right size.

The tip shape of this bit makes it difficult to drill through softer, traditional plastic. In this case, you need to pre-drill a pilot hole to prevent it from bouncing.

As far as polyethylene is concerned, this bit works well.

Image

Pros

  • Tough drill bit.
  • Won’t crack hard plastics.
  • Removes chips efficiently.

Cons

  • A little expensive.

Overall value rating

⭐⭐⭐⭐

 

6. CO-Z Step Drill Bits

If you’re going to drill many holes of different sizes in soft or medium-density plastics, having a set of step drill bits like this can be very useful.

The set has a lot of different bits, and they’re all fairly reasonably priced.

Due to the titanium coating, the durability is excellent for their relatively low price. Unless you’re drilling plastic forever, these bits are practically indestructible.

They are also designed specifically not to walk, so they make drilling holes much easier. Additionally, they are compatible with 1/2′′, 3/8′′, and 1/4′′ chuck sizes.

This set is the best pick for those who like the idea of drilling plastic with step bits.

Image

Pros

  • Excellent value for money.
  • Very tough, when used on plastic.
  • Easy to make super-clean holes.
  • Works with lots of different chuck sizes.

Cons

  • Won’t work for anything harder than acrylic.

How To Find The Best Drill Bits For Plastic

Now we’ll discuss some key things to consider when buying drill bits for plastic.

What types of drill bits are best for plastic?

If you use the right technique, you can drill through plastic with traditional masonry bits or wood bits. When drilling through plastic, these types of bits tend to leave an uneven surface because they are designed to bite into the material.

The best drill bits for plastic are spur bits (also known as dowel bits or Brad points). Four-point tips result in a cleaner entry point and a cleaner hole with these bits.

Alternatively, you can create the depression with a countersink bit. This serves the same purpose as a dowel bit – it ensures that the bit is lined up correctly and does not move during drilling.

People sometimes use step drill bits to drill plastic, to prevent having to switch bits each time they drill a different-sized hole. In addition, you can use these bits without a countersink bit to start your hole.

What about the different types of plastic?

There are a huge number of different types of plastic that you can drill into.

It will be more difficult to drill into acrylic, polycarbonates, and other hard plastics than softer plastics, such as polyethylene. In fact, if you drill the material incorrectly, you can easily crack it, leading to the need to restart the project.

As you begin drilling, the harder your material is, the greater the risk of cracking/chipping. Drill bits will be more crucial as a result.

In any case, it does not mean that drilling into other types of plastic is simple. It may be easier to drill into thin, soft plastic if you place some scrap wood behind it.

Will plastic wear down my drill bits?

If you are planning to drill into plastic, you have to take that into account as well.

The most important thing to remember when drilling into plastic is that the tip remains sharp. It is more likely that your bit will cause jagged/rough cuts into the material when it becomes dull over time.

Drill bits wear down faster in hard plastics. When you get a good drill bit, it shouldn’t become dull, like a masonry bit might after drilling lots of bricks or concrete.

Can drill bits for plastic be used to drill other materials?

Drill bits made for plastic should not be used on wood or masonry, or vice versa.

In general, these types of material will wear down your tip more quickly, making the bit much less effective against plastic.

Plastics are more susceptible to damage when they are drilled with metal and masonry bits, which are designed to bite into the material.

Wood bits, while performing a little better, might not have the perfect tip to drill through plastic cleanly.

Is it worth buying a drill bit set?

You can use a single 3/16′′ drill bit to make holes in a plastic lid if all you need is to poke some holes.

It’s a great idea to go for a set if you frequently work with acrylics or other plastics.

Plastic drill bit sets usually come with five to ten different bits. It means you get different sizes, so you can make holes of different diameters, as well as spares in case you accidentally cut your tip.

However, you should pay attention to the bits included in a given set. When you’re never going to use a drill bit, there’s no point in buying it. Having access to every drill bit you’re going to need every few months, however, can be handy.

Another nice thing about sets is that they often come with nice holding cases. As a result, you’ll always have easy access to your drill bits without having to dig around for them, which is nice.

As compared to wood, concrete, or aluminum, plastic can be extremely brittle when drilling.

You can try taping the top and bottom sides of thin material, and then drilling through the tape to prevent cracking.

Using any other type of bit can create a hole that is difficult to clean, making it imperative to use a drill bit designed for plastic.

You should drill with consistent and firm pressure, to prevent the bit from moving as you drill.

Use a slow setting to allow the chips to escape the hole quickly. When it comes to plastics, friction and heat buildup is the last thing you want.

The drill bit tends to “grab” the material when drilling smaller objects, making it difficult for the drill bit to hold. Be sure to clamp them properly. Getting a Brad point bit, however, should greatly reduce grabbing.
