3D printed drill guide


To drill holes through T-Slot profiles accurately you would usually use a drill press to make sure that you produce accurately positioned holes. we realize that not everyone has access to a drill press and so in order to help you, we have created these 3D-printed drill guides which you can download and print.

With the addition of 2 bearings and some T-nuts and bolts, you will be ready to start drilling holes in your T-Slot profiles whenever you need to.


What is a drill guide?

A drill guide is a small device that can be clamped in position on the profile to guide the drill in a straight line when drilling by hand. The guide will help you to place drill holes accurately and neatly. The 3D printed guide is intended for occasional and light-duty work, it will help you to get your smaller project done and is very useful for when you need to drill a hole on site. For drilling lots of holes, we recommend using a drill press.

Why do you need a drill guide?

When you need to drill a hole through the center of a T-Slot Aluminium profile to do a standard connection it is important to drill accurately. this means that the drill needs to be exactly perpendicular to the profile. The best way to do this is to clamp your material in a drill press. If you don’t have a drill press available the next best method is to use a drill guide. The drill guide is also indispensable when you need to add a drill hole to an existing frame, for example, if you need to make a modification to a frame that is already installed in a factory.
