Diamach 125mm x 150mm Longreach Diamond Core Drill
High-Performance Stone & Masonry Core Bit (SKU: 125CORESTONELONG)
The Diamach 125mm x 150mm Longreach Diamond Core Drill is the ultimate heavy-duty solution for fast, clean, and deep-hole drilling in high-density materials. Engineered specifically for demanding trade applications, this professional-grade core bit features an extended 150mm drilling depth and a substantial 125mm cutting diameter, making it ideal for running pipework, structural anchors, and drainage holes through tough substrates.
Equipped with a highly versatile dual-thread connection, it seamlessly incorporates an M14 internal thread and a 1/2-inch Gas BSP external thread. This universal design allows direct mounting onto high-speed angle grinders, hand-held stone polishers, industrial water swivels, or advanced CNC machinery without requiring frustrating aftermarket adapters.
Whether you are a stonemason profiling premium granite or a concrete specialist drilling thick masonry, the 125CORESTONELONG delivers exceptional tool longevity, rapid material penetration, and clean, chip-free finishes.
Key Features & Benefits
• Extended 150mm Drilling Depth: Engineered with an extra-long barrel to tackle thick masonry walls, deep stone slabs, and concrete in a single pass.
• Dual-Thread Versatility (M14 & 1/2" Gas): Offers universal compatibility. Universal internal M14 threading fits standard angle grinders, while the external 1/2" Gas thread integrates perfectly with wet-feed swivels and automated CNC machines.
• Premium Diamond Matrix: Infused with commercial-grade diamond segments engineered to self-sharpen, maintaining a high cutting speed through hard aggregates.
• Wet & Dry Operational Flexibility: Capable of dry cutting for quick jobs, though highly optimized for wet drilling to drastically extend tool life and completely suppress hazardous dust.
• Clean, Chip-Free Holes: The advanced segment geometry minimizes breakout on the exit side of the material, preserving the structural integrity of your workpiece.
Material Compatibility
This commercial-grade core drill bit is optimized for aggressive cutting across heavy masonry and natural stone applications:
• Excellent Performance: Granite, Engineered Stone, Sandstone, Quartzite, and Limestone.
• Construction Materials: Reinforced Concrete, Solid Brickwork, Blockwork, Cinder Blocks, and General Masonry.
• Product Limitation Note: This segment matrix is explicitly designed for stone and masonry; it is not recommended for ultra-hard porcelain or brittle ceramic tiles.

Pro-Tool User & Safety Tips
1. Dust Suppression: To strictly comply with modern safety standards regarding crystalline silica dust, always operate this core drill wet whenever possible.
2. Speed & Pressure Management: Let the diamond segments do the work. Avoid applying excessive downward pressure, which can overheat the matrix and glaze the diamonds.
3. Tool Adaptability: If your setup requires an SDS+ or standard hex-shank power drill, separate Diamach adapter shanks can be easily retrofitted to the M14 thread base.
