Vacuum Brazed Diamond Chamfer&Finger Bit for Ceramic/Porcelain/Stone

This product series comprises vacuum brazed diamond chamfer bits and finger bits designed for edge profiling and surface grinding applications on ceramic tiles, porcelain, marble, and granite. The range includes multiple models (JD868202058, JD8682020M14, JD868202558, JD8682025M14, JD868223558, JD8682235M14, JD868205058, JD8682050M14) with diameter ranges from 0–20mm to 0–50mm, chamfering diamond heights of 20mm–42mm, a consistent grinding diamond height of 30mm, lengths of 60mm–82mm, and thread options of 5/8”-11 or M14, catering to precise chamfering and grinding needs from light to heavy-duty tasks.

a. Product Features and Advantages:

• Vacuum Brazing Technology: Ensures strong adhesion of diamond particles to the matrix, delivering superior durability, efficient material removal, and precise performance for chamfering and grinding.
• Integrated Chamfering & Grinding Function: Combines edge chamfering and surface grinding capabilities in one tool, streamlining workflows for multi-step profiling.
• High-Quality Diamond Coating: Features a textured, silver-grey metallic diamond-coated surface with dense abrasive particles, providing excellent wear resistance and aggressive cutting action.
• Diverse Model Specifications: Offers 8 models with varying diameters (0–20mm to 0–50mm), chamfering heights (20mm–42mm), lengths (60mm–82mm), and thread types (5/8”-11/M14) to match different equipment and application requirements.
• Precision Design: Pointed tip for intricate detailing, paired with a cylindrical blue shank (marked “20MM” for working length/diameter and “5/8”-11” for standard threading), ensuring stable mounting on rotary tools (grinders/drills) and clean edge formation.
• Wide Material Compatibility: Suitable for hard materials including ceramic, porcelain, marble, and granite, maintaining consistent performance across surfaces.

b. Product Applications:

Ideal for edge chamfering and surface grinding on ceramic tiles, porcelain, marble, and granite. Specifically used in construction, tile-laying, and stoneworking projects for creating clean edges, intricate detailing on countertops, and precise profiling of tiles or stone slabs.
