Borrhuvud: unveiling the essence of drill heads

When delving into the world of drilling, one cannot ignore the pivotal role played by the borrhuvud, commonly known as drill heads. These inconspicuous yet indispensable components are the unsung heroes behind the precision and efficiency of drilling operations.

At its core, a borrhuvud is the business end of a drill, the part that directly engages with the material being drilled. Understanding its intricacies is paramount for anyone seeking to master the art and science of drilling.

The anatomy of borrhuvud

Let’s dissect the borrhuvud to comprehend its anatomy. Typically made from robust materials such as high-speed steel or carbide, the drill head comes in various shapes and sizes. The choice of material and design depends on the specific drilling task at hand.

The primary components include the cutting edges, flutes, and shank. The cutting edges are the sharp protrusions responsible for creating the initial hole, while the flutes aid in chip evacuation, preventing clogging during the drilling process. The shank, on the other hand, connects the drill head to the drilling machine.

Types of borrhuvud

Borrhuvud comes in an array of types tailored to different applications. Twist drill heads, for instance, are ubiquitous and versatile, suitable for a wide range of materials. On the other hand, spade drill heads excel in creating large-diameter holes, making them ideal for specific tasks.

Specialized drill heads like diamond-tipped heads cater to the demands of robust materials like concrete and ceramics. Understanding the nuances of each type ensures optimal performance in diverse drilling scenarios.

Choosing the right borrhuvud

The selection of the appropriate borrhuvud is a critical aspect of any drilling operation. Factors such as material hardness, drill bit speed, and the desired hole size play pivotal roles in making the right choice. Ignoring these considerations can lead to inefficiencies, premature wear, and even damage to the drilling equipment.

Consulting the drill head manufacturer’s guidelines and understanding the specifications of the drilling machine are imperative steps in ensuring a seamless and effective drilling experience.

Maintenance and longevity

Like any other tool, borrhuvud requires proper maintenance to prolong its lifespan and ensure consistent performance. Regular inspection for wear and tear, timely sharpening, and adherence to recommended usage guidelines contribute to the longevity of these crucial components.

Investing in high-quality borrhuvud and following a robust maintenance routine not only enhances the efficiency of drilling operations but also proves cost-effective in the long run.


Q: how often should i sharpen my drill head?

A: The frequency of sharpening depends on the intensity of use. As a general rule of thumb, inspect and sharpen the drill head if you notice a decline in performance or witness signs of wear.

Q: can i use the same borrhuvud for different materials?

A: While some drill heads are versatile, it’s advisable to use specialized ones for specific materials. This ensures optimal performance and extends the life of the drill head.

Q: what precautions should i take during drilling to prevent overheating?

A: Ensure proper lubrication, use the recommended cutting speed, and periodically withdraw the drill to allow for effective chip evacuation. These measures help prevent overheating and prolong the life of the borrhuvud.
