A Guide to Drill Bit Extensions

Have you ever been in a situation where your drill bit was just not long enough to reach the area where you needed to drill? In this article, we will discuss why drill extensions are very important and how they can help solve these problems. We will also give an overview of what some of the best options on the market look like.

What is?

A drill bit extender is a tool that lengthens the product and allows you to make holes deeper in a variety of materials. Counterintuitively, an additional accessory should be slightly smaller than the diameter of the bit itself. When using such an additive, you should carefully adjust cutting modes when drilling.

How does a drill bit extension work?

Drill extensions work by lengthening the product for increased reach which allows for more depth of penetration into materials like metal, concrete block, tile boards just about anywhere!

How to use a drill bit extension?

It’s not hard to use a drill extension. All you have to do is make sure that your device is set up in the right cutting mode, such as high speed or reverse drilling. Put it on and proceed with caution, making sure that everything stays aligned while you are drilling and turning the pieces until they fit together into place when needed.

What size of an extension do I need?

The size of the extension you need is determined by measuring your drill bit and then subtracting the length that will be used after adding in a little buffer.

What size of shank do I need?

The shank size is the diameter of the drill bit extension. It’s important to make sure it fits your chuck size. Usually it fit one on this sizes: ¼” hex shank, ¾” hex shank or the metric equivalent.

Hex or round shank?

The most common drill bit extension is the hex shank. They come in a variety of lengths and diameters, but it’s important to note that not all drills are compatible with them. To find out whether your drill is compatible, you’ll need to examine its shank size – usually found on the side or front of the handle – then make sure whichever extensions you’re considering purchasing match up accordingly.

Hex or round collet?

The most common drill bit extension, and the one that’s compatible with any drill you might have, is the hex collet.
