Diamond cutting disc Diam 350 x 25.4/10 mm BS70 laser, professional (DIBS70350/25)

Professional Diam diamond cutting disc model DIBS70350/25 is a high-capacity 350 mm diameter blade with a dual-size centre hole (25.4/10 mm) designed for demanding cutting tasks on masonry, concrete and similar hard materials. The BS70 laser-segment configuration provides a balance of cutting speed and segment durability, making the disc suitable for use on compatible angle grinders and stationary cutting machines where the specified bore fits. The construction focuses on precise, straight cuts and sustained performance under frequent operation.

Advantages

The BS70 laser-segment design increases cooling and debris evacuation during cutting, reducing overheating and preserving segment life. A robust bonding of diamond grit with the matrix ensures consistent cutting efficiency on abrasive materials such as concrete and masonry. The dual-size centre hole allows compatibility with a range of machine arbors when the appropriate reducer or adapter is used, and the 350 mm diameter provides deeper cutting capacity compared with smaller discs.

Suitable for

• Cutting reinforced and non-reinforced concrete
• Masonry block and brick cutting
• Large-format paving and stone trimming
• Use on angle grinders and stationary cut-off saws with compatible bore mounting

Key specifications

• Diameter: 350 mm
• Centre bore: 25.4/10 mm (dual-size configuration)
• Segment type: BS70 laser-segment
• Intended materials: masonry, concrete and similar hard building materials
• Application: wet and dry cutting depending on machine capability and recommended practice

How to use

Mount the diamond disc on an appropriate angle grinder or stationary cutting machine ensuring the machine arbor matches the disc centre hole or using the correct adaptor. Verify the disc is correctly secured and that the rotation direction marked on the disc corresponds with the machine. Use steady, even feed pressure and allow the disc to perform the cut without excessive force. When cutting reinforced concrete, make multiple shallow passes if required rather than forcing a single deep cut. Follow the machine manufacturer's safety instructions and wear suitable personal protective equipment including eye, hearing and respiratory protection.

Usage recommendations

To maximise disc life and cut quality, use appropriate cooling (wet cutting where possible), avoid prolonged idling under load, and store the disc in a dry environment. Match cutting speed and feed rate to the material; for particularly abrasive materials perform test cuts to determine optimal parameters.
