A roll pin is a type of fastener that has a cylindrical shape and slightly tapered ends. It is used to secure two or more pieces of material together. In order to remove a roll pin from a blind hole, you will need a few tools including a punch, hammer, and vice.
First, use the punch to gently tap the roll pin until it starts to loosen from the hole. Next, use the hammer to lightly strike the end of the punch until the roll pin pops out of the hole. Finally, use the vice to grip the end of the roll pin and twist it until it comes free from whatever it was securing.
- Using a punch slightly smaller than the roll pin, drive the roll pin until it is flush with one side of the blind hole
- Place a drift punch on the opposite side of the blind hole and gently tap it with a hammer to start driving the roll pin out from the other side
- Continue driving the roll pin out until it is completely removed from the blind hole

How to Remove a Broken Roll Pin from a Blind Hole
If you’re working on a project that involves a blind hole, there’s a good chance you’ll need to remove a broken roll pin at some point. Here’s how to do it:
1. Start by drilling a pilot hole in the center of the roll pin.
This will give you something to grip onto when you start extracting the pin.
2. Next, use a pair of pliers or vice grips to grab onto the pilot hole you just drilled. Apply pressure and twist the roll pin until it starts to come out of the blind hole.
3. Once the roll pin starts to come out, use a punch or other sharp tool to drive it the rest of the way through the blind hole. With any luck, this will dislodge the broken piece and allow you to remove it from your workpiece entirely.

How Do You Remove a Hard Roll Pin from a Blind Hole?
There are a few different ways that you can remove a hard roll pin from a blind hole, but the most common method is to use a drift punch. First, you’ll need to identify the center of the roll pin. Once you’ve found the center, align the tip of the drift punch with it and gently tap the punch until it penetrates the roll pin.
Next, continue to apply pressure to the punch while rotating it in a clockwise direction. As you rotate, the roll pin will begin to unscrew from the hole. Finally, remove the punch and roll pin from the hole.
How Do You Remove a Groove Pin?
A groove pin is a type of fastener that is used to secure two pieces of material together. It consists of a small metal pin with a grooved head that fits into a matching slot in the other piece of material. The pin is then driven into the slot using a hammer or other tool, and the two pieces are locked together.
To remove a groove pin, you will need to use a tool called a drift punch. This is a long, thin rod with a pointed end that is used to drive out pins and nails. Place the tip of the drift punch against the head of the groove pin, and tap it with a hammer until the pin pops out of the hole.
How Do You Remove Spring Dowel Pins?
Dowel pins are one of the most commonly used fasteners in the world. They are simple, strong and easy to use. However, they can be a bit tricky to remove, especially if they are stuck in place.
In this blog post, we will show you how to remove spring dowel pins quickly and easily.
The first thing you need to do is identify the dowel pin that you want to remove. Once you have found it, take a look at the surrounding area.
If there is any debris or rust around the pin, you will need to clean it off before proceeding.
Once the area is clean, apply some penetrating oil to the dowel pin. This will help loosen it up and make it easier to remove.
Let the oil sit for a few minutes before trying to remove the pin again.
If the pin still won’t budge, you may need to use a punch or other tool to drive it out from behind. Be careful not to damage the surrounding area while doing this.
Finally, once the dowel pin has been removed, inspect it for damage and replace if necessary.
What Size Hole Do I Drill for a Roll Pin?
When it comes to drilling holes for roll pins, size really does matter. If the hole is too small, the pin won’t be able to properly grip and secure whatever it is you’re trying to fasten. On the other hand, if the hole is too large, the pin will have a lot of wiggle room and could eventually work its way out.
So what’s the perfect size hole for a roll pin?
The best way to determine this is by using a drill bit that’s slightly smaller than the diameter of the pin itself. This will allow for a snug fit that won’t be too tight or too loose.
Keep in mind that you’ll also need to take into account the thickness of whatever material you’re drilling through. For example, if you’re attaching a roll pin to a piece of wood, you’ll want to use a thinner drill bit than you would if you were attaching it to metal.
In general, it’s always better to err on the side of caution and go with a slightly smaller hole rather than risk making it too big.
With that said, there are some cases where using a slightly larger drill bit can actually be beneficial.
Conclusion
It’s not uncommon to need to remove a roll pin from a blind hole. While there are a few different ways to do this, the most common is to use a drift punch. Here’s how:
First, start by drilling a small pilot hole in the center of the roll pin. This will give you something to start with when using the punch. Next, insert the drift punch into the pilot hole and tap it gently with a hammer until it starts to drive the roll pin out of the hole.
You may need to wiggle the punch around a bit as you go to get it started, but once it’s moving, just keep tapping until the roll pin pops out.
