Diamond Cutting Disc Distar CLASSIC H12 125 x 2.2/1.3 x 22.23 mm

Diamond cutting disc Distar CLASSIC H12 125 x 2.2/1.3 x 22.23 mm is a diamond rim blade designed for use with angle grinders to cut hard materials such as concrete, natural and artificial stone, brick and ceramics. The segmented rim with diamond abrasive delivers fast, precise cuts while the 125 mm diameter and 22.23 mm arbor make it compatible with a wide range of handheld grinders used in construction and renovation work.

Advantages

The Distar CLASSIC H12 disc combines a thin cut width with a durable segment thickness to balance cutting speed and blade life. Its diamond rim ensures consistent performance on abrasive building materials, providing accuracy and reduced chipping on ceramic and stone surfaces. The blade’s construction supports stable rotation at typical angle grinder speeds, helping to maintain straight cuts and minimise material waste.

Suitable for

• Cutting reinforced and plain concrete
• Cutting natural stone and engineered stone
• Trimming and cutting brick and paving blocks
• Cutting ceramic tiles and porcelain
• On-site renovation and finish carpentry tasks requiring angle grinders

Key specifications

How to use

Mount the disc on an angle grinder with a matching 22.23 mm arbor and secure it according to the grinder manufacturer’s instructions. Use appropriate personal protective equipment including eye protection, hearing protection and dust mask. Start cutting with light steady pressure, allowing the diamond rim to do the work; avoid excessive force that can overheat the blade. For wet cutting use only if the disc and tool are rated for wet operation; otherwise carry out dry cuts with intermittent pauses to reduce heat buildup. Follow safe operating speeds and machine limits indicated by the angle grinder.

Usage recommendations

For best results, select cutting speeds and feed rates appropriate to the material: slower feed for dense stone and faster, controlled passes for softer masonry. Replace the disc when segments show significant wear or when cutting becomes inconsistent. Store the disc flat in a dry place to preserve diamond segment integrity.
