Diamond Core Bit SPECIALIST WAART Rounded Cylinder Cutter 10–25 mm, M14 shank

Diamond core bit SPECIALIST WAART Rounded Cylinder Cutter 10–25 mm, M14 shank is a precision diamond abrasive tool designed for drilling holes with diameters between 10 and 25 mm. The rounded cylinder cutting head provides controlled cutting action and consistent hole quality in hard materials that require diamond-grade abrasiveness. The M14 threaded shank fits angle grinders and other rotary tools that accept M14 accessories, allowing use with standard power tools for rapid material removal and accurate hole formation.

Advantages

The diamond-impregnated cutting head ensures long-lasting cutting performance and maintains sharpness when working on dense or abrasive substrates. The rounded cylinder geometry reduces chipping at the edges of drilled holes and promotes stable penetration. The M14 shank provides secure connection to compatible angle grinders and rotary tools, enabling high-speed operation and straightforward accessory changes. The tool is suitable for precise, repeatable hole drilling where dimensional accuracy and surface integrity are important.

Suitable for

• Drilling precise holes in ceramic tiles and porcelain
• Creating openings in natural and engineered stone
• Punching holes in glass and glazed surfaces with controlled feed
• Forming holes in concrete and masonry for light fixtures or anchors
• Installation tasks requiring 10–25 mm diameter holes

Key specifications

• Cutting head shape: rounded cylinder
• Drilling diameter range: 10–25 mm
• Shank type: M14 threaded shank compatible with M14 tool spindles
• Abrasive material: diamond-impregnated cutting edge for hard substrates
• Intended use: dry or wet drilling depending on material and tool recommendations

How to use

Fit the M14 shank securely into the tool spindle and tighten according to the power tool manufacturer's instructions. Mark the hole location and start drilling at low speed to establish the initial position, then increase speed with steady, moderate pressure. Depending on the material, use intermittent feed or cooling to prevent overheating—apply water when recommended for the substrate and tool. Withdraw the cutter periodically to clear debris and check the hole diameter. Maintain a perpendicular angle for straight holes and avoid lateral forces that can fracture the cutting head or the workpiece.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, gloves, and respiratory protection when drilling dusty materials. For tile, glass and stone, water cooling is often recommended to prolong tool life and improve hole quality; for masonry or concrete follow the power tool manufacturer's guidance on wet versus dry use. Check compatibility with the specific angle grinder or rotary tool and ensure the maximum allowed RPM of the cutter matches the tool speed.
