20-35-50mm Diamond Step Chamfer Drill Bit - High-Quality Tools from China Suppliers and Factory
Product Overview
This diamond step chamfering drill bit is a professional tool designed for efficient and multi-functional stone and masonry work. It is compatible with both wet and dry environments and can be safely applied to various materials such as ceramic tiles and marble. The core design features three step sizes (20mm, 35mm, 50mm) and a unique step chamfering shape, enabling drilling, reaming, edge grinding, and chamfering in a single operation, significantly improving installation efficiency and precision. Its M10 threaded interface is specifically designed for 100mm angle grinders, ensuring a secure and reliable connection.
Product Features
Vacuum Brazing Process
Utilizing advanced vacuum brazing technology combined with high-concentration, high-quality diamond, faster cutting speeds and significantly extended tool life are achieved.
Multifunctional Stepped Chamfer Design
The unique integrated structure of steps and chamfers can not only drill standard holes, but also easily enlarge holes, grind and chamfer stone, making it an essential tool for installers.
Cracking Prevention and Finishing
Effectively reduces the risk of cracking in standard and large-format tiles (such as in areas under tension, such as when installing pipes or LED lights). At the same time, it significantly improves the edge finish of exposed holes, achieving a more professional appearance.
Exceptional Adaptability and Compatibility
Supports both wet and dry operation, adapting to various working conditions. The three-step size provides extensive operational flexibility, while the M10 thread ensures a perfect match with common 100mm angle grinders, guaranteeing a secure installation.
M10 Standard Threaded Interface
Featuring an M10 standard threaded interface, specifically designed for 100mm angle grinders, the interface offers a high degree of fit, ensuring a secure fixation after installation and minimizing the risk of loosening or shifting. During high-speed rotational machining, it maintains a stable machining state, preventing tool vibration from affecting machining accuracy and providing a solid guarantee for precise and safe drilling and chamfering operations.
Frequently Asked Questions
QWhat materials can this diamond step chamfering drill bit be used on?
This drill bit is designed to work on a wide range of hard materials, including ceramic tiles, marble, and general stone or masonry surfaces. It is suitable for both standard and large-format tile applications.
QCan this drill bit be used for both wet and dry cutting?
Yes. This drill bit supports both wet and dry operation, making it highly adaptable to different job site conditions. Wet cutting is generally recommended for extended use to prolong tool life and reduce dust.
QWhat are the three step sizes available on this drill bit?
The drill bit features three integrated step sizes: 20mm, 35mm, and 50mm. This allows operators to drill, ream, and chamfer at different diameters in a single tool without switching accessories.
QWhich angle grinder is this drill bit compatible with?
This drill bit features an M10 standard threaded interface, which is specifically designed for 100mm (4-inch) angle grinders. The threaded connection ensures a secure, vibration-resistant fit during high-speed operation.
QHow does the vacuum brazing process benefit tool performance?
The vacuum brazing process bonds high-concentration, high-quality diamond particles to the bit under controlled conditions, resulting in superior bond strength. This leads to faster cutting speeds, reduced heat buildup, and a significantly longer tool lifespan compared to conventional electroplated bits.
QCan this drill bit help prevent tile cracking during installation?
Yes. The stepped chamfer design effectively distributes stress during drilling, reducing the risk of cracking — especially in tension-prone areas such as around pipe openings or LED light recesses. The chamfering action also delivers a clean, finished edge on exposed holes for a more professional result.
