HSS bi-metal hole saws (crown saws) for professional and precise drilling work

Do you want to saw or drill large holes in hard materials? Then HSS bi-metal hole saws, also known as crown saws, are the right choice. These hole saws are specially developed for professional use and are available in various diameters, so you always choose the right size for your application. They are widely used on the job site and in the workshop for various tasks within construction, installation, and metalworking.

HSS bi-metal hole saws are excellent for boring holes in steel, stainless steel, aluminum, wood, and plastic. Thanks to the combination of hardened HSS teeth and a reinforced cobalt alloy, these saws have a very high wear resistance. This results in a long lifespan, stable performance, and a lower risk of breakage, even with intensive use. Through our webshop, you can easily purchase HSS bi-metal hole saws that fit your project and machine.

What are HSS bi-metal hole saws and crown saws?

HSS bi-metal hole saws consist of two different materials that together form one strong saw. The saw teeth are made of High Speed Steel (HSS), while the body of the saw is flexible and impact-resistant. Due to this bi-metal construction, the saws combine sharpness, durability, and break resistance.

Crown saws are used to saw round holes with a larger diameter, where standard drills fall short. They are a staple in professional drilling work where accuracy and reliability are essential.

Applications of bi-metal hole saws

HSS bi-metal hole saws are used for a wide range of applications. They are suitable for cutting holes in metal such as steel and stainless steel, but also in aluminum, wood, and plastic. This makes them ideal for installation work, construction work, ventilation openings, and technical passages. Due to their versatility, these hole saws are used in sectors such as construction, industry, metalworking, and HVAC installations.

HSS bi-metal hole saws in various diameters

HSS bi-metal hole saws are available in a wide range of diameters, allowing you to choose the right size for each application. Smaller diameters are often used for precise passages and fixings, while larger diameters are suitable for technical installations and ventilation openings. Diameters around 20 to 40 mm are ideal for cable passages and light assembly work, while 60 to 80 mm are widely used for electrical junction boxes. For larger applications, such as pipes and ventilation, HSS bi-metal hole saws with a diameter of 100 mm to 160 mm or larger are the preferred choice.

By working with the right diameter, you prevent unnecessary wear and achieve a clean drilling result. In combination with a suitable centering drill and holder, this ensures efficient and safe drilling work, both on the job site and in the workshop.

HSS bi-metal hole saws versus other hole saws

Compared to standard HSS hole saws, HSS bi-metal hole saws offer a significantly longer service life and better performance with hard materials. While simple hole saws wear out or break faster, bi-metal hole saws stay sharper and more stable for longer. For very hard or abrasive applications, carbide or diamond solutions may be suitable, but for general professional drilling work, HSS bi-metal hole saws are the most versatile and economical choice.

Working safely and efficiently with hole saws

To work safely and efficiently with HSS bi-metal hole saws, it is important to maintain the correct speed and provide sufficient cooling during metalworking. A stable setup and regularly removing chips extend the lifespan of the saw and ensure a clean drilling result. By using it correctly, you limit wear and reduce the chance of jamming or breaking of the hole saw.
