25mm Diamach Longreach Diamond Core Drill 150mm Depth M14 and 1/2 Inch Gas Attachments 25CORESTONELONG
The 25mm Diamach Longreach Diamond Core Drill (SKU: 25CORESTONELONG) is an industrial-grade masonry and stone drilling tool engineered for trade professionals. It is uniquely configured with dual-mounting connections: an internal M14 thread to mount directly onto high-speed angle grinders, and a 1/2" Gas (BSP) male thread to connect seamlessly into specialized core drill rigs, water swivels, and CNC machinery.
Boost your workshop’s production output with the Diamach 25mm Longreach Diamond Core Bit. Standard tiling hole saws from competing brands are built shallow, capping out at a limited 35mm to 60mm cutting depth. The Diamach Longreach series shatters those limitations by providing a massive 150mm drilling depth capacity in a single pass, completely erasing the need for tedious core-snapping pauses or specialized barrel extensions.
Whether executing deep anchors, roughing-out plumbing lines, or running complex architectural stonemasonry details, this heavy-duty core drill delivers pristine, chip-free results through granite, engineered quartz, natural marble, reinforced concrete, brick, and dense sandstone.
Key Performance Advantages
- True Deep-Coronary Barrel: The industrial 150mm long body is engineered specifically for boring deeply into thick structural retaining walls, substantial masonry blocks, and heavy stone kitchen counter slab fabrications.
- Dual Spindle Adaptability: The hybrid design houses an M14 grinder mount alongside a 1/2" Gas thread, letting operators switch instantly from handheld grinder cutting on-site to high-torque CNC workstation routing.
- Optimised Material Clearance: Specially formulated diamond segment structures quickly eject slurry when running wet, preventing dangerous bit-binding inside deep stone channels.
- Versatile Cutting Modes: While running the tool wet maximizes segment lifespan, it safely supports dry drilling patterns in standard masonry and brick configurations when equipped with proper HEPA dust extraction.
Pro-Targeting Operation Tips
- Angle Grinder Startup: Because small-diameter core drills lack a centering pilot pin, always start your plunge at a 30-degree tilt to establish a stable crescent guide-track before swinging the tool smoothly up to a perpendicular 90-degree drilling plane.
- Speed Management: Keep operating speeds steady. Running at an excessive RPM burns the premium matrix bonding, while cycling with light, oscillating pressures allows dust to clear efficiently.
