Andis Clipper Guards Sizes

Let’s start with Andis’s most popular accessory: the brand’s Nano-magnetic combs. The company divides them into two sets – four longer magnetic guards and five shorter. The reason these are so revered is their secure and tight fit, durability, and facilitation of more precise and easier haircuts.

We can assure you that these combs are not going anywhere. And whenever you need to remove them, you’ve to pull quite hard to get them off! It is insane how securely they fit on there from just a small magnet.

Besides, they’re also compatible with some other models of the hair clipper. For example, Andis magnetic guards can fit on Oster Fast Feed without any problem. Make sure to get the double magnetic guards. Here is the Andis magnetic guards size chart itself!

A few of Andis professional clippers and trimmers come with ceramic blades. What is great about them is their longevity, their cool operation mode, and, you know, their overall style. Andis clipper’s ceramic blades will net you up to 70% cool operation, which is great for heavy-duty haircuts. An alternative to ceramic would be the UltraEdge blades, which, however, are not made of this material.

The most popular CeramicEdge blade is Andis BGRc. Andis detachable blades also fit other top hair clippers like the Oster Classic 76. Here is the ceramic Andis clipper blades size chart to help you out.

These blades come in almost all the hair clipper sizes that you’d expect and are shaped exactly as the carbon steel ones. Warning: they are more fragile than the steel version. So, take a close look at the blade to make sure none of the teeth have been chipped or broken.
