CNC Straight Router Bits For Engraving Marble Granite
CNC Straight Router Bits, specifically engineered for engraving and milling hard stones like marble and granite. These tools are made from cemented carbide (tungsten steel), with diamond-impregnated or specially coated cutting edges to withstand the high hardness and abrasiveness of stone. As seen in the image, the bits have a tapered body with a sharp cutting tip and a standard threaded shank at the bottom, designed to be mounted on CNC engraving machines or machining centers for tasks such as flat engraving, contour cutting, and grooving.

Key Characteristics
🔹Cemented Carbide Body: The tool body is made of high-hardness, wear-resistant tungsten steel, ensuring it does not deform or chip under high-intensity cutting.
🔹Diamond Cutting Edge: The cutting tip is embedded with diamond particles or features a special wear-resistant coating, effectively resisting stone abrasion and maintaining long-term sharpness.
🔹Straight Flute Design: The straight flute design is ideal for linear cutting, grooving, and flat milling, offering high processing efficiency.
🔹Standard Threaded Shank: The bottom features a standard thread (e.g., 1/2"G), allowing for easy installation on various CNC engraving machine spindles, ensuring high versatility.
🔹High-Precision Machining: Precision-ground cutting edges ensure a smooth surface finish and dimensional accuracy, reducing the need for subsequent polishing.
🔹High Durability: The robust overall structure is suitable for long-duration continuous operation, making it ideal for industrial production environments.
Usage Scenarios
🔹Stone Engraving: Used for deep engraving of text and patterns on marble and granite tombstones and monuments.
🔹Countertop Grooving: Cutting grooves in kitchen or bathroom countertops for installing sinks, faucets, and other fixtures.
🔹Building Facade Processing: Machining edges and connection grooves on stone facade panels.
🔹Floor Stone Inlay: Cutting and engraving patterns for stone floor inlays.
🔹CNC Machining Centers: Widely used in various CNC stone machining centers for automated, high-precision mass production.
🔹Stone Craft Production: Used in the creation of stone sculptures, decorative items, and other crafts.
