Ochrana korunkového vrtáka Smart365 5–10 mm, HEX, 4-dielna

Smart365 hole saw set 5–10 mm, HEX, 4 pieces contains four diamond-edge hole saws with HEX shanks in sizes 5 mm, 6 mm, 8 mm and 10 mm. The set is intended for cutting precise small-diameter circular holes in materials compatible with diamond cutting edges. The HEX shank ensures a secure, torque-resistant connection with compatible drill chucks or holders and simplifies bit changes during plumbing, electrical installation and general DIY tasks.

Advantages

The diamond cutting rims provide accurate, clean holes with reduced chipping on brittle surfaces. The HEX shank design prevents slippage in the drill holder and transmits torque efficiently for controlled cutting. A compact 4-piece range covers common small-hole sizes used for pipes, cables and fasteners, reducing the need to stop and change tools. The set is lightweight and convenient to store, making it suitable for both on-site and home use.

How to use

Select the hole saw with the required diameter and insert the HEX shank into a compatible chuck or quick-change holder. Secure the shank firmly to avoid wobble. For brittle or fragile materials, start drilling at low speed and use light, steady pressure to allow the diamond edge to grind the material. Apply cooling or intermittent drilling if recommended for the material to avoid overheating. After cutting, withdraw the tool carefully and clear any debris from the cutting edge before storing.

Recommendations

Use appropriate personal protective equipment, such as safety glasses and gloves. Match the work speed and cooling method to the material being cut — for tile and glazed surfaces, use water cooling and low to moderate speeds; for other compatible materials follow manufacturer guidance. Do not use the diamond hole saws on materials not compatible with diamond abrasives to avoid tool damage.
