Anyone who has ever machined a metal part knows that the material must be deburred before it is finished. It is essential because burrs and flash holes will affect your parts’ performance and can even break them down to their base materials. But what if you need to remove these imperfections but don’t know how?

A flash hole is a small gap between two pieces of metal created when the material was cut and separated. During machining, sometimes these holes are not filled in with swarf or removed entirely before being finished; therefore, they produce an imperfection on one side of the part. 

Dealing with machines can be an invitation for burrs on your workpieces. The functionality of the part of the product continuously gets affected, and you need to rely on a professional to get it cleaned. But now, you can rely on yourself but just buying the right deburring tool to have smooth components back again.

Here’s a guide for you all that will explain what causes a burr, how to remove it, and which are the best flash hole deburring tools.

Before learning about hole deburring tools, let’s have a glance at some unfamiliar terminologies.

What is burr?

A burr is a sharp and rough protrusion that may be found at the edge of metal. It can also occur on surfaces where different materials meet, like metal meeting plastic, or wood. Usually, this happens when parts are coming together which have varying degrees of hardness.

What is deburring?

Deburring removes sharp edges by using different types of tools like files or grinding wheels to make them less pointed, so they don’t split materials apart while being cut, smashed into pieces, or just otherwise coming into contact.

What causes Burr?

Burring is very common during the process of machining. Burrs can be caused by:

  •         Turing
  •         Milling
  •         Grinding
  •         Drilling
  •         Plasma cutting
  •         Laser cutting and much more

Types of burrs:

Moreover, the burrs form in three different types too.

Breakout burrs:

A break-out burr is when a sharp edge has been created on the top of the surface, and it’s not yet broken through. This type of burring can be fixed using various tools to file or grind down that area until it is no longer sharp.

Poisson Burrs:

This type of burr will have a sharp edge created on the side or at an angle. It needs to be filed down before it can come into contact with other materials, but if you’re not careful, then you’ll create a new burr in another area.

Rollover Burrs:

These are the simplest ones, and they usually occur near edges where there is an abrupt change from one material to another. They need to be ground down to don’t cause any damage when anything comes into contact with them – like your hands.

So how do you know if there are any flash holes?

The best way to find out for sure is what architects call “throwing light” onto workspace surfaces from different angles to see where the light falls into an opening. That means shining a flashlight at your project piece, which will help show gaps between materials and, even more importantly, Flash Holes! You’ll want to take care of these as soon as possible before they weaken your piece.

Other Ways To Remove Burrs

Following are some other ways that can be used for deburring.

Abrasive blast cleaning is one way to remove the burr. This process uses an abrasive material like sand to clean the metal and make it smooth again. It also removes paint, rust, oil, dirt, or any other contaminants that may have built up on top of the surface.

Using a wire brush wheel with a rotary tool will work as well when you want more control over what area gets cleaned off by hand instead of blasting it from afar in a uniform fashion. 

Other methods for removing these protrusions include grinding machines; lathes; grinders such as cylindrical grinders, bench grinders, vertical spindle grinders; carbide drills (or drills with carbide tips); wire brush machines; and hand tools like screwdrivers, files, scrapers, and sandpaper.

FAQs

When burrs are hard to access, such as those in the cross-holes of tubular components, there are more efficient ways to deburr than by hand. Standard methods include applying brushes, mounted points, sphere-shaped rotating tools, flexible abrasives, and rotating tools with replaceable HSS or carbide blades or inserts.

Deburring tools remove burrs and smooth parting lines, jagged edges, or protrusions on the surface of an object created during machining or casting operations. Chamfering tools are used to create a beveled edge at the intersection of two surfaces, typically at 45 degrees.

It depends on what type of tool you are using. Still, mostly, people prefer brushing their barrels before they do any other cleaning. It removes most of the dirt and carbon built up inside before scrubbing down with chemicals or solvents, leading to corrosion over time.

You must wash and dry your rifle every time after shooting. To help remove any fouling from the bore, use an ultrasonic cleaner or place it in a container with soapy water for about 15 minutes.

The flash holes didn’t need any deburring, but the pockets did. If primer pockets get too dirty with carbon, it can interfere with fully seating new primers.
