Set of 10 diamond hole saws, Zola, diameter 6-68 mm, 500-900 rpm, suitable for drilling hard materials.

The set includes 10 diamond-coated hole saws, ideal for professionals or amateurs who require reliable, durable, and efficient tools for drilling hard materials. With this complete kit, precise work is achieved on tiles, ceramics, glass, marble, granite, or porcelain without the risk of surface damage or breakage.

Each hole saw features an electroplated diamond coating, providing clean, smooth, and fast drilling. They are designed to offer maximum flexibility, covering the most common diameters for household or industrial installations. From small holes for expansion screws to large diameters for electrical panels or iron connections, this set ensures you always have the right diameter available.

An important advantage of these hole saws is their durability and high performance. The thick steel body and diamond coating provide wear resistance and long service life, even with intensive use. Additionally, their design allows efficient heat dissipation, helping maintain performance over time.

For optimal results, it is recommended to use the hole saws wet, that is, with continuous water cooling. This method reduces friction, prevents overheating, and ensures precise drilling. However, they can also be used for dry drilling, although their lifespan will be shorter.

Important usage instructions:

• Prepare the surface before use, ensuring it is clean and kept wet throughout the operation.
• Start drilling at a 45° angle to prevent the hole saw from slipping.
• Once the tip has penetrated the material, gradually bring the drill to a vertical position and continue drilling at medium speed (500–900 rpm).
• Do not apply excessive pressure; let the tool work on its own.
• Always use water for cooling – a spray bottle or a wet sponge is enough to protect the diamond coating and extend the hole saw's lifespan.

The set includes 10 hole saws with the following diameters:

• 6 mm, 8 mm, 10 mm – ideal for expansion screws
• 16 mm – suitable for bases and threads
• 20 mm, 28 mm – for heating pipes and domestic hot water
• 35 mm, 45 mm, 50 mm – used for batteries and drainage
• 68 mm – ideal for electrical panel installation

The hole saws come in a practical protective case for easy storage and transport, keeping them safe and organized so they are ready for use whether you are in the workshop or on site.
