Cylindrical drill bushing / guide bushing: DIN 172 - DIN 179

Drill bushings

What is a drill bushing?

Drill bushings, also called guide bushings, are essential components in machining operations such as drilling or counterboring. They are hollow cylinders with a through axial hole, designed to precisely guide a cutting tool such as a drill bit.

Once inserted into a pre-drilled hole (via a drilling template), the bushing is used to hold and guide the cutting tool, allowing for increased precision and avoiding any deviations.

Why use drill bushings?


Drill bushings are a quick and efficient solution for drilling parts in batches without the need for measurements or prior markings. This handy tool guides the drill straight into the template, allowing you:

  • Maximum precision thanks to the preset drill angle and hole depth.
  • Perfectly uniform, ideally suited to batches of several dozen, hundred or thousand parts.
  • They also save you a considerable amount of time as they simplify the machining process.


Unlike manual drilling, using a guide bushing gives you guaranteed clear, consistent results, while reducing the risk of errors.


Drill bushings offer a quick and effective solution for batch-drilling parts without the need to measure or mark the holes. These handy tools guide the drill bit directly into the drilling device, ensuring a personalised drill template and preventing any drill deviation.

The different types of drill bushings

At Gardette Industries, we offer various types of drill bushings:


DIN 179 drill bushings are known for their cylindrical shape, and are an ideal solution for positioning and precision. They are easily configurable for an optimal user experience.

Our standard drill bushings come in form A, i.e. the hole is rounded at one end.



The collar on DIN 172 standard drill bushings means you have total control of positioning when drilling - thanks to this collar, they don't sink to the bottom when used. That's why the collar on DIN 172 guide bushings is slightly raised.

When should drill bushings be used?



As previously mentioned, drill bushings are used for precision machining processes.



Drill bushings can be found in many different sectors, such as:

  • Aviation
  • Manufacturing tools for the automotive sector
  • All sectors where CNC machining is used



These drill bushings allow you to make precise, consistent holes repeatedly, guiding your drill bit with extremely high precision.

Made of quenched steel with a hardness of 63/65 HRC, Gardette Industries drill bushings offer excellent wear resistance and a particularly long lifespan.

Advantages of Gardette Industries drill bushings
