DIAMACH 80mm Longreach Stone & Masonry Diamond Core Drill (80CORESTONELONG)
Bore deep, perfect holes through heavy substrates with the DIAMACH 80mm D x 150mm L Longreach Stone and Masonry Diamond Core Drill (80CORESTONELONG). Engineered in Australia by DIAMACH, this trade-tier core drill bit is designed specifically for professional commercial tilers, stonemasons, and plumbing contractors who require flawless, production-grade holes through thick, dense materials.
Standard tiling hole saws and core bits from competing brands feature shallow barrels that cap out at a limited 35mm to 60mm cutting depth. The DIAMACH Longreach Series shatters those performance boundaries by providing a massive 150mm drilling depth capacity in a single pass. This deep-barrel design eliminates the need for tedious core-snapping pauses, barrel extractions, or specialized extensions, allowing you to bore cleanly through double brick walls, structural blockwork, and thick natural stone countertops without interruption.
The engineering cornerstone of the 80CORESTONELONG is its highly versatile dual-spindle mounting layout. It features a hybrid integration of an M14 internal thread—allowing it to mount directly onto standard high-speed angle grinders—alongside an external 1/2" Gas male thread designed to lock seamlessly into specialized core drill rigs, CNC machinery, and production workstations. High-density industrial diamond matrix segments deliver an exceptional service life, working effortlessly through ultra-hard porcelain panels, natural granites, engineered quartz, sandstone, and masonry blockwork.
Why Choose the DIAMACH 80mm Longreach Core Drill?
• True 150mm Core Depth: Massive 150mm body length allows you to bore deep drainage paths, conduit feeds, and anchors in one fluid step.
• Hybrid Dual Thread Configuration: Integrates an M14 female mount and 1/2" Gas male fitting to support instant transitions from handheld grinder cutting to heavy CNC or rig drilling.
• High-Concentration Diamond Matrix: Premium segment chemistry stands up to continuous cutting wear, resisting segment glazing or premature breakdown.
• Wet or Dry Adaptability: Supports high-efficiency wet drilling to clear stone slurry instantly, or dry drilling configurations on masonry when paired with appropriate extraction and PPE.
• Australian-Backed Tooling: Developed and distributed by DIAMACH, Sydney’s preferred brand for industrial diamond consumables and specialized architectural masonry gear.
Professional Operation Tips
• Centering and Entry: Because deep stone core drills lack a central pilot pin, always start your plunge at a 30-degree tilt. Once the diamond segments score a stable crescent guide track into the surface, smoothly swing the machine up to a perpendicular 90-degree plane to finish the bore.
• Maximize Bit Lifespan: While this core drill can be used dry with care, utilizing a continuous water feed completely suppresses hazardous silica dust, cools the diamond segment matrix, and significantly extends the tool's overall working life.
