Everything You Need to Know About Cranial Drills
Complete Guide to Cranial Drills: Types, Uses, and Essential Tips
Cranial drills are indispensable tools for professionals who perform circular cuts in materials such as wood, metal, concrete, stone, stainless steel, and others. With different configurations and specific features, these drills ensure precision and functionality across various fields such as construction, electrical, hydraulic, and sanitary installations. Let’s explore how these drills work, the correct way to use them, and the main benefits they offer.
How to Use Cranial Drills
To use cranial drills effectively and safely:
- Choose the right drill for the material to be cut (metal, stone, wood, concrete, etc.).
- Check the fitting: for example, an SDS Max drill requires specific hammers to ensure a secure connection.
- Lubricate when necessary: for stainless steel or heavy metals, it is recommended to use cutting oil to ease the process and increase tool durability.
- Use accessories: some models require a pilot drill or adapters, which help start the cut precisely and prevent the tool from slipping at the beginning of drilling.
- Work steadily and at moderate speed, allowing the drill to cut without applying excessive pressure, thus preserving the tool’s lifespan.
After understanding how cranial drills work and the best usage practices, it’s important to choose the ideal drill for each specific application. PECOL offers a variety of cranial drill models, each designed for specific needs and materials, ensuring optimal results every time.
Below, we present the main types of cranial drills and the benefits each one can bring to your work.
Cranial Drill for Metal
Made from M2 steel, the HSS M2 Cranial Drill is ideal for those seeking high durability and resistance for frequent metal drilling. The central spring system facilitates material removal, making the work faster and more efficient. Cuts are precise and burr-free, saving time and ensuring a professional finish.
Applications: Recommended for precise drilling in metals up to 7–8 mm thick, as well as in tubes and round surfaces.
The HSS Cranial Drill for Magnetic Drill Presses is designed to deliver high-precision cuts in metals such as iron, steel, and aluminum. Made from HSS steel, it offers superior durability and provides smooth, burr-free cuts even in harder materials. Specifically developed for magnetic drill presses, it ensures stability and efficiency in industrial applications.
Applications: Ideal for use in metalworking, steel construction, and other industries that require high-precision metal cutting.
Cranial Drill for Stainless Steel
The HSS Cranial Drill for Stainless Steel (TCT) features a tungsten carbide tip that provides superior strength, essential for drilling hard materials such as stainless steel, reducing wear and extending its service life. The use of cutting oil during the process is recommended to keep the temperature under control and further increase durability.
Applications: Suitable for drilling tough surfaces such as stainless steel, cast iron, and steel alloys, as well as for cutting curved surfaces and metal profiles.
Cranial Drill for Concrete and Stone
The SDS Max HD Cranial Drill is made with tungsten carbide tips that provide robustness and precision for cutting construction materials such as concrete and brick. This model facilitates deep and accurate drilling. The optimized design allows for faster drilling, saving time and ensuring high-quality finishing.
Applications: Ideal for sanitary installations, ventilation, central heating, and holes for switch boxes. It is widely used by installers and electricians in civil construction projects.
Bi-Metal Cranial Drill for Wood
The Bi-Metal Hole Saw offers fast and precise circular cuts in a wide range of materials, such as aluminum, wood, drywall, and laminated plastics. Made from M2 high-speed steel, it ensures superior durability and efficient performance, with a cutting depth of up to 38 mm. The variable tooth pitch design reduces effort and noise during use, providing smooth, burr-free cuts. Recommended for drills in rotary mode, it is a tool for those seeking efficiency and precision.
Applications: Suitable for work in areas such as plumbing, carpentry, and electrical installations.
