    Extra Coarse Grit Tools for Aggressive Cutting & Contouring

    Discover the power of extra coarse diamond burs engineered for rapid, aggressive material removal. Our Extra Coarse Grit collection is specifically designed for dental professionals and industrial technicians seeking high-performance rotary instruments that deliver consistent results with minimal effort. These dental burs extra coarse options provide enhanced durability, long service life, and superior shaping capabilities.

    Coarse Grit Abrasives for Rapid Material Removal

    When precision and speed are critical, coarse grit abrasives are the tool of choice. Whether you're reshaping ceramics or contouring hard surfaces, our extra coarse rotary instruments offer unmatched cutting power. The abrasive grit levels in this collection range between 60 to 120 grit—perfect for shaping and debulking with accuracy and control.

    Understanding Grit Classification and Grit Number Scale

    The grit size chart is key to selecting the right tool. A lower grit number, such as 60 or 80, indicates a coarser grain, ideal for heavy-duty cutting. Our extra coarse grit dental burs are suited for procedures that require removing large amounts of material quickly. These burs are designed to endure repeated use while maintaining their sharpness and cutting edge.

    Shaping and Contouring Burs Built for Speed

    Each bur in our collection is tailored for coarse surface preparation and rough shaping. The aggressive texture allows for effective use in dental lab procedures, surgical preparation, or industrial grinding tasks. The tools are built with precision to ensure efficient removal without compromising surrounding structures or material integrity.

    Why Choose Extra Coarse Grinding Burs for Dental Labs?

    1. Superior durability: Crafted for repeated use in high-friction environments.
    2. Fast cutting speed: Reduces chair time and enhances procedural efficiency.
    3. Shape variety: Available in flame, wheel, round, and taper forms.
    4. Multi-application: Ideal for rough contouring, debulking, or crown prep.
    5. Long service life: Maintains cutting efficiency over time.

    FAQs about Extra Coarse Grit

    What grit is extra-coarse?

    Extra-coarse grit typically ranges between 60 to 80 on the grit number scale, making it suitable for heavy material removal and surface shaping. In abrasive grit levels, this range provides highly aggressive cutting and is commonly used in grinding tools, rotary dental burs, and sanding discs. Extra coarse diamond burs in dentistry are designed to remove enamel or ceramic material quickly during procedures like crown prepping or tooth shaping. Always refer to the grit size chart to match your application needs—lower numbers indicate coarser textures that cut faster but leave a rougher finish.

    What does coarse grit mean?

    Coarse grit refers to an abrasive grade with larger particles, generally ranging from 40 to 100 grit. This grit is ideal for removing excess material and performing rough shaping tasks in both dental and industrial applications. In dental burs, coarse grit abrasives are used for procedures like rapid tooth reduction or ceramic adjustment. The lower the grit number, the more material is removed with each pass. Tools labeled as coarse grit are more aggressive and are not intended for finishing or polishing but rather for foundational shaping and coarse surface preparation.

    What grit is DMT extra-coarse?

    DMT extra-coarse products typically feature a grit level of 60 microns, equivalent to about 220 mesh or 60 grit on traditional abrasive scales. These sharpening tools are designed for the most aggressive material removal, whether you're sharpening blades or reshaping hard substances. In the dental field, similar extra coarse grit diamond burs serve comparable purposes, offering fast cutting performance and durability. When choosing extra coarse grinding tools, always consider the type of material and the required finish level. DMT grit classification helps users identify the appropriate tool for rough grinding and initial shaping.

    Is 1000 grit coarse?

    No, 1000 grit is not considered coarse—it falls into the fine grit category. Used mainly for polishing and finishing, 1000 grit is suitable for smoothing surfaces rather than removing large amounts of material. In contrast, extra coarse grit tools range from 40 to 80 grit, making them ideal for shaping and contouring. In dental applications, a 1000 grit bur would be ineffective for procedures requiring aggressive cutting. Instead, opt for extra coarse diamond burs when quick reduction or rough grinding is needed. The grit number scale helps differentiate coarse from fine abrasive levels.

    What does grit stand for?

    Grit refers to the abrasive particle size on a cutting, grinding, or polishing tool. It measures the coarseness or fineness of the abrasive surface—lower grit numbers indicate coarser abrasives that remove material faster, while higher grit numbers are used for smoothing or polishing. For example, extra coarse grit tools may be rated at 60–80 grit, making them perfect for rapid contouring or debulking in dental burs or grinding instruments. Understanding the grit classification helps professionals choose the right tool for their task, ensuring both speed and surface quality.

    Which is coarser, 100 or 180 grit?

    100 grit is coarser than 180 grit. In the grit number scale, lower numbers represent larger abrasive particles, which are more effective for heavy material removal and coarse surface preparation. 100 grit tools are often used for aggressive shaping or smoothing down rough materials, while 180 grit is better suited for light sanding or pre-polishing. In dental applications, using a 100 grit extra coarse diamond bur allows faster tooth reduction compared to finer burs. Always match the grit level to your task—choose coarser grits for speed, and finer ones for precision and polish.
