Rosfix Hole saw set for metal, steel, wood, 5 pieces (16mm/18.5mm/20mm/25mm/30mm) Set of titanium coated HSS core drill bits for wood, steel and metal A hole saw set is a collection of tools that are used for drilling holes in various materials, such as metal, steel and wood. The set includes five hole saws with different diameters: 16 mm, 18.5 mm, 20 mm, 25 mm and 30 mm. Each of these hole saws has a specially designed blade that allows for precise and efficient drilling in appropriate materials. Hole saws are extremely useful tools for professionals and DIY enthusiasts who regularly work with various materials. Using different hole saw diameters allows you to adapt the size of holes to your specific needs. A set of five hole saws allows you to drill holes of different diameters, which is especially useful for a variety of projects. With these tools, you can easily create holes in furniture, metal structures, or other items, increasing their functionality and adapting them to your individual needs. High-quality materials: These taper drill bits are made of high-quality HSS high-speed steel, ensuring their durability and strength.

Specification: Material: 4341 HSS with titanium coating 16 mm 18.5 mm 20 mm 25 mm 30 mm Intended use: Metals Wood Plastics For best results when drilling steel , it is recommended to keep the speed at a maximum of 380 rpm. The correct speed is crucial as it ensures precise and efficient drilling while minimizing the risk of damage to the tool or material. For copper, zinc, nickel, brass and aluminum, the rotation speed should be slightly higher. For these materials, we recommend drilling at a maximum rotation speed of 480 rpm for copper, zinc, nickel and brass, and 580 rpm for aluminum. Adapting the rotation speed to the material type guarantees optimal drilling performance and precision. For even better results, we recommend using oil when drilling. Lubricating oil significantly helps the hole saw glide through the material, reducing friction and extending the tool's life. Additionally, the oil also protects the tool from overheating during operation. It's also worth noting that the hole saws in this set are equally effective for drilling holes in wood. When drilling wood , it is recommended to maintain a minimum speed of 1000 rpm to ensure smooth and efficient drilling.
