Why choose the 80mm SDS+ hole saw? Key benefits
When working on a construction site or during home renovation, two things are crucial: speed and precision. This diamond hollow core saw has been developed with maximum productivity and long service life in mind. Here are the main benefits of using this top-of-the-line tool:

Exceptional durability and quality of materials: The saw is made of high-quality alloy steel, which is resistant to high loads and overheating. The teeth made of premium carbide alloy BK8 (sintered carbide) ensure exceptional sharpness and long service life, even when drilling frequently in hard materials.
Fast and clean cutting: Brazed tungsten carbide teeth are ideal for cutting clean, regular and precise holes without chips on the edges.
Efficient dust and chip removal: The spiral core of the crown reduces friction during operation, while special exhaust holes on the outside of the cylinder allow for continuous dust and chip removal. This prevents clogging and extends the life of the tool.
Universal SDS Plus system: The included adapter with M22 thread allows quick and easy mounting on all rotary hammers and drills with SDS Plus clamping system. Changing is quick, safe and requires no special tools.
Precise centering: The integrated TCT guide with a pointed drill bit ensures stability at the start of drilling, prevents the crown from slipping and enables faster and extremely precise hole positioning.

Versatile use for various building materials
This 80 mm diameter diamond core saw is perfectly optimized for making holes for electrical installations, junction boxes, switches and sockets. It is suitable for processing a wide range of construction materials:

Classic and reinforced concrete
Red and silicate brick
Gypsum-cement boards and gypsum boards (Knauf)
Clinker and various wall tiles
Other related building materials

Instructions for safe and effective use
To achieve the best results and maximize the life of your hole saw, we recommend following these steps:

Assembly: Screw the hole saw onto the M22 threaded adapter and insert the pilot drill. Then clamp the adapter into the SDS Plus head of your drill.
Starting drilling: Start drilling with the pilot drill installed at lower speeds to create a stable pilot hole.
Drilling without impact: We recommend drilling without using the impact function (especially with more delicate materials), as this maintains the sharpness of the carbide teeth and prevents damage to the material around the hole.
Walking and cleaning: During prolonged drilling, periodically pull the core saw out of the hole to allow dust to escape and the material to cool.

Frequently Asked Questions (FAQ)
1. Is this core saw suitable for drilling into reinforced concrete?
Yes, the core bit is designed for drilling into concrete and brick. However, special care is required when drilling into reinforced concrete (with iron reinforcement). If the drill bit hits a steel bar, drill slowly and without excessive pressure to prevent damage to the BK8 carbide teeth.
2. What kind of drill do I need to use this hole saw?
To use this hole saw, you need a hammer drill or a more powerful drill with an SDS Plus chuck. The included 100 mm adapter fits perfectly into this standard chuck system.
3. Is a pilot centering drill included in the package?
Yes, the package includes a complete set, which includes an 80 mm hole saw, an SDS Plus adapter with M22 thread, and a TCT pilot drill bit, which allows for extremely precise centering without slipping.

Instructions for using the product:
• Check that the saw is properly assembled and ready for use. Check that all parts are properly installed and secured.
• Before starting work, make sure you have the appropriate protective equipment, including safety glasses, gloves, and headphones.
• Before using the saw, check that the blade is properly installed and secured. Make sure the blade is clean and sharp.
• Before starting cutting, make sure that the work area is well lit and that there are no obstacles that could interfere with your work.
• Hold the drill firmly and steadily while cutting. Do not press too hard, but let the blade do its work.
• After finishing work, turn off the drill and put the saw in a safe place. Wait for the blade to come to a complete stop before removing or storing it.

Useful tips for work:
• When cutting, wear appropriate protective equipment such as safety glasses, gloves and earplugs. This will protect your eyes, hands and hearing from possible injury.
• Before starting work, make sure the work area is well lit. Good lighting will allow for more accurate drilling and reduce the chance of errors.
• Hold firmly and steadily while drilling. Do not press too hard, but let the blade do its work. Too much pressure can cause damage to the blade or an uneven cut.
• After finishing work, turn off the drill and put it in a safe place. Wait for the blade to come to a complete stop before removing or storing it.
• Maintain your saw regularly by cleaning it after each use and regularly checking the condition of the blade. If the blade is damaged or worn, replace it with a new one.

Warnings:
• Before drilling, always check the wall for electrical cables, pipes or other hidden wiring.
• Wear safety glasses, hearing protection and appropriate respiratory protection when working, as drilling concrete and brick produces a lot of dust.
• It is also recommended to use protective gloves when handling the crown, as the cutting edge has sharp or hard segments.
• Before changing or removing the hole saw, switch off the power tool and disconnect it from the power supply or remove the battery.
• Do not use a damaged, cracked or deformed crown.
• Do not use excessive force or attempt to stop the crown by hand.
• Drilling can cause strong vibrations and torque, so always hold the tool with both hands if the tool design allows it.
• The core saw is intended for drilling suitable building materials; do not use it for materials for which it is not intended.
• After finishing work, wait until the crown has completely stopped, as it can become very hot during operation.

Answers to frequently asked questions

For which materials is this diamond core saw best suited?

The hole saw is specially designed for precise drilling of holes in concrete and brick, making it suitable for most masonry and assembly tasks in these materials.

Can the saw be used with all SDS+ drills?

Yes, the SDS+ connection allows use with most standard drills with this attachment, but we recommend checking the maximum allowed diameter with the manufacturer of your tool.

What should I consider for a long blade life?

It is recommended to use the saw exclusively for the intended materials, work with intermediate breaks if necessary, and avoid excessive pressure while drilling, as this reduces wear on the diamond segments.

Can I use the saw for both dry and wet cutting?

Always check the manufacturer's label before use; most diamond core saws allow for both dry and wet drilling, but wet drilling is recommended for optimal results and less dust.

Is this saw suitable for professional use or just for occasional projects?

The 80 mm diameter model is more geared towards occasional or hobby projects and smaller electrical installations; for intensive professional use, we recommend checking out specialized models designed for heavier loads.
