# The PGM standard, a guarantee of quality for concrete drills

When it comes to drilling concrete or masonry, precision and safety are essential criteria. The PGM standard “Prüfgemeinschaft Mauerbohrer e.V.” ensures that drill bits for these materials meet rigorous quality standards, ensuring efficient and reliable drilling. Let's look at the importance of this standard and what it entails, based on information from the video on the certification of PGM concrete drills.

The PGM standard is a certification issued by an independent body based in Germany, which evaluates and validates concrete drills according to precise technical criteria. Created in 1978, this standard has established itself as an essential standard for building professionals and experienced do-it-yourselfers. It ensures that certified drill bits are compatible with modern anchoring systems, such as dowels, and offer optimal results in terms of safety and performance.

# PGM evaluation criteria

PGM-certified drill bits are subject to strict controls, covering several key technical aspects:

1. Dimensional accuracy

• The diameter and height of the cutting plates must be within very precise tolerances. This ensures regular drilling, which is essential for the use of dowels and anchors.
• These specifications are particularly important in applications where fastener safety is critical, such as for suspended structures or heavy installations.

2. Concentricity and eccentricity

• The PGM standard verifies that the cutting plate is perfectly centered and aligned. Poor concentricity can lead to irregular or overly large holes, compromising the hold of the ankles.
• This feature also ensures better stability when drilling, reducing vibration and the risk of deflection.

3. Wear resistance

• PGM drill bits are designed to withstand heavy use on abrasive materials such as concrete or brick. The standard ensures that the tools retain their effectiveness even after many drilling cycles.

The PGM-certified drill bits guarantee a perfectly calibrated drilling, ensuring optimal anchor hold. This is essential for jobs where fastener safety is critical, such as suspended structures, heavy installations, or anchors in load-bearing walls.

Non-compliant drill bits can create irregular or overly wide holes, compromising the effectiveness of the dowels and increasing the risk of fastener failure. In contrast, PGM-certified drill bits are designed to produce precise and uniform holes, minimizing these risks.

2. Compliance with European standards

PGM-certified drills meet the requirements of the European Technical Assessments (ETEs), especially for dowel extraction tests. These standards ensure that the products meet quality standards that are recognized throughout Europe, especially in the context of the use of dowels for structural loads. By choosing PGM drills, you automatically comply with the regulations in force, a crucial point for building professionals.

For example, PGM drills are specifically tested for applications that match documents such as EAD 330232, which is for metal dowels in concrete. These tests involve tight tolerances on hole diameter and consistency, which are critical factors for the durability and safety of anchors.

3. Outstanding accuracy

A PGM-certified drill bit stands out for its precision. With rigorous control of the concentricity and eccentricity of the cutting head, these drills ensure a straight, well-aligned drill. This is especially important in projects where multiple holes need to be aligned to accommodate dowels or fasteners.

This accuracy also reduces the chances of damage to the surrounding material, such as cracks in the concrete or weakening of the areas near the hole. This not only preserves the aesthetics of the structure but also ensures its long-term solidity.

4. Durability and resistance

PGM-certified drill bits are designed to withstand heavy use on abrasive materials such as concrete, brick or stone. Thanks to the use of high-end materials, such as tungsten carbide, and an optimized design, these drill bits offer increased durability. They retain their performance even after many drilling cycles, making them economical in the long run.

Plus, their wear resistance means you can use them for demanding projects without fear of rapid tool degradation. This reduces the need for frequent replacement, a definite advantage for professionals who work on jobsites where productivity is a priority.

5. Versatility in applications

PGM drill bits are suitable for a wide range of applications, from electrical or sanitary installations to renovation or construction projects. Their ability to drill through a variety of materials, including reinforced concrete, makes them versatile tools for do-it-yourselfers and professionals alike.
Whether it's for small-diameter holes for lightweight dowels or larger holes that require structural anchors, PGM drills provide reliable and consistent performance.

6. Recognition and Quality Assurance

The PGM logo, engraved on certified drills, is a visible assurance of their compliance with the strictest standards. It certifies that the product has been tested by an independent body, thus providing transparency and a guarantee of quality. This marking inspires confidence in professionals and individuals alike, allowing them to choose tools they can rely on.

# How do you recognize a PGM-certified drill bit ?
