Have you ever needed to drill an exact depth? Look no further, as we introduce you to the world of drill stops. These affordable accessories can help you achieve precision and efficiency in your drilling projects. In this article, we will explore what drill stops are, how to use them, and provide some alternative options. So, let’s dive in and discover the power of drill stops!

The Power of Drill Stops: Achieve Precision and Efficiency

What are Drill Stops?

Drill stops, also known as depth stops or collars, are essential tools for achieving specific drilling depths. They fit around your drill bit, allowing you to control the depth and prevent the drill from going any further. Drill stops are available in various sizes to accommodate different drill bit sizes, ensuring versatility in your projects.

How to Use a Drill Stop

Using a drill stop is incredibly easy. Simply slide the collar over the drill bit and position it at the desired depth. Tighten the collar using a hex key, ensuring a secure fit. Now, you’re ready to drill your hole! The drill stop will prevent the drill from exceeding the set depth, guaranteeing consistent results.

Tightening Mechanism

Drill stops can also be used with other types of drill bits, such as Spade or Forstner bits. To use them with these bits, you’ll need an additional accessory. Slip a collar of a similar size as the shank (usually 3/8″) onto the bit, then attach a “jig it” drill guide. This combination will not only limit the drilling depth but also ensure perfectly perpendicular holes.

DIY Depth Stops

If you’re a DIY enthusiast looking for a budget-friendly alternative, you can make your own depth stop! This method allows you to create a custom stop for any drill bit size. Here’s how:

  1. Determine the length of the drill bit that should protrude from the wood.
  2. Cut a piece of scrap wood to match that length.
  3. Drill a hole through the scrap wood using the desired drill bit.
  4. Slide the piece of wood onto the drill bit, and you now have your homemade drill stop.

This method provides flexibility, as you can easily customize the depth stop for different drill bit sizes. Plus, if you have leftover scrap wood lying around, it’s a perfect way to put it to good use!

Alternative Options

While drill stops are highly effective, there are other options available if you don’t require absolute precision or need to make repeated holes.

Mark with a Marker

For less critical drilling tasks, such as avoiding drilling all the way through the wood, you can simply mark the desired depth on your drill bit using a wet-erase marker. This allows you to visually control the depth and prevent over-drilling. If you only have a permanent marker, you can remove the mark by rubbing alcohol or a whiteboard marker over it.

Masking Tape

Another quick and easy alternative is using masking tape to mark the desired depth on the drill bit. Although not as durable for repeated holes, masking tape serves as a temporary depth guide.

Drill Presses

If precision and efficiency are paramount in your projects, investing in a drill press is highly recommended. Drill presses not only provide accurate depth control, but they also ensure perfectly vertical holes. Most drill presses come with built-in depth stops, making them the ideal option for repetitive drilling tasks. However, keep in mind that the size of your workpiece must fit on the drill press table.

Plunge Routers

When it comes to drilling holes of a specified depth, plunge routers excel. These versatile tools are designed for precision, although they may have limitations in terms of depth due to the short length of router bits.


Q: What is the purpose of a drill stop?
A: A drill stop allows you to control the drilling depth and prevent the drill from going any deeper, ensuring consistent results.

Q: Are drill stops compatible with all drill bit sizes?
A: Yes, drill stops are available in various sizes to accommodate different drill bit sizes, providing versatility for your projects.

Q: Can I create my own depth stop?
A: Absolutely! You can easily make a DIY depth stop using scrap wood and customize it for any drill bit size.


Drill stops are invaluable tools for achieving precise drilling depths. Whether you choose to invest in a set of drill stops or make your own, they offer the convenience and accuracy needed for various drilling projects. With drill stops, you’ll enjoy efficient and consistent results, saving you time and effort. So, equip yourself with the power of drill stops and take your drilling skills to the next level!
