Diamond Cutting Blade dr.schulze SHARK HARD 350 mm / 25.4 mm bore

Diamond cutting blade dr.schulze SHARK HARD 350 mm with 25.4 mm bore is a professional cutting tool designed for hard and abrasive construction materials. The blade combines a reinforced core with a diamond cutting rim engineered for precise, efficient cuts in masonry, natural stone, concrete and similar substrates. It fits angle grinders and power saws that accept a 25.4 mm arbor and is intended for tasks where a segmented or continuous rim is required to balance cut speed and edge quality.

Advantages

The SHARK HARD blade offers long life and consistent cutting performance due to its optimized diamond grit distribution and robust steel core. Its design reduces vibration and ensures straight, accurate cuts with minimal chipping on hard materials. The 350 mm diameter provides a deep cutting capacity suitable for many construction and renovation applications while the 25.4 mm bore ensures secure mounting on compatible machines.

Suitable for

• Cutting masonry blocks and bricks
• Cutting natural stone such as granite and sandstone
• Cutting reinforced and plain concrete
• Short runs on tiles and pavers when a hard-rim blade is required
• Use with compatible angle grinders and cut-off saws with 25.4 mm arbor

Key specifications

• Diameter: 350 mm
• Bore (arbor) diameter: 25.4 mm
• Cutting rim: diamond (hard rim, suitable for abrasive/hard materials)
• Construction: reinforced steel core with diamond-bonded edge
• Typical applications: masonry, stone, concrete, pavers

How to use

Select a power tool compatible with a 25.4 mm arbor and ensure the machine's maximum RPM rating matches or exceeds the blade's rated speed. Mount the blade following the tool manufacturer's instructions, making sure it is secured and oriented correctly. Use steady feed pressure; avoid forcing the blade to extend blade life and reduce risk of binding. For best results on hard materials, make progressive passes rather than attempting a single deep cut. Always allow the blade to spin up to full speed before contacting material and let it slow naturally before stopping work.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection, gloves and respiratory protection when cutting dusty materials. Use water cooling if recommended by the tool or blade manufacturer to extend blade life and reduce dust when cutting certain stone types. Inspect the blade before each use for damage, and do not use a blade that is warped, cracked or excessively worn.
