ADI Tools STONE WORM Diamond Core Drill Bit – 10mm Shank and Side Slot

ADI Tools STONE WORM Diamond Core Drill Bit – 10mm Shank and Side Slot

The ADI Tools STONE WORM diamond core drill bit is a high-quality professional tool, specifically designed for drilling stone materials on CNC machinery and machining centres. Thanks to its advanced construction technology, which combines a robust steel body with a high-performance diamond crown, it is the ideal choice for creating non-through ("blind") precision holes with an impeccable finish.

Main Features

• Application Versatility: Specifically engineered for drilling marble, granite, natural stones, and abrasive materials, ensuring high and consistent performance across all types of stone surfaces.
• Side Discharge Slot: Functional design featuring internal water-feed compatibility, which ensures the rapid expulsion of swarf and processing debris. This technology prevents the diamond crown from overheating, significantly increasing both tool life and drilling speed.
• 10mm Straight Shank: Universal standard fitting, perfectly compatible with the tool holders and spindles of CNC machinery and machining centres.
• ADI Tools Certified Quality: Choosing an ADI Tools product means relying on a global leader in the diamond tool industry—a synonym for extreme reliability, millimetric precision, and an unbeatable durability-to-cost ratio.

Application Materials

The Stone Worm core bit has been rigorously tested to deliver excellent cutting performance and a clean finish on:

• Granite: Effective across all hardness classes, from the softest to the most abrasive stones.
• Marble and Limestone: Ideal for precision drilling without the risk of surface chipping.
• Quartz Agglomerates: Designed for engineered and synthetic materials (such as Silestone®, Okite®, and similar).

Technical Specifications

• Model: STONE WORM
• Manufacturer: ADI Tools
• Drilling Type: Wet use (internal cooling to maximise performance and tool life)
• Shank Diameter: 10 mm (Straight/Cylindrical shank)
• Available Diameters: Ø 4 – 5 – 6 – 8 – 10 mm
• Design: Steel body with side discharge slot for debris extraction

Usage Recommendations

To maximise the diamond crown's service life and ensure excellent results, the following guidelines are recommended:

• Cooling: Always use a generous supply of water (internal cooling). Constant lubrication is essential to achieve clean holes, even on the hardest and most compact materials.
• Working Pressure: Avoid applying excessive pressure during drilling; allow the quality of the ADI Tools diamond to perform the cut progressively.
• Swarf Management: The side slot is designed to facilitate cooling and the automatic expulsion of debris, but it is vital that the water flow remains continuous to prevent the buildup of abrasive slurry.

Why choose Stone Worm?

Unlike common low-cost core bits, the ADI Tools Stone Worm ensures a constant feed rate and a chip-free finish, drastically reducing processing times and the risk of material breakage.
