Diamond Hole Saw Selected alloys, fast, precise, and stable hole opening! Reinforced brazing, easy to cut, no deformation! Suitable for a variety of scenarios, precise and durable choice! Specification: Size: 8.2*8*8 cm Weight: 205 g Color: as shown in the picture Material: alloy Packing list: 1* 68 mm alloy drill bit Note: 1. Regardless of the hardness of the material you are drilling, adding water will help lubricate and cool the drill bit, effectively extending the life of the hole saw and reducing the replacement frequency. 2. Be sure to wear safety glasses and gloves during operation, keep the work area well-lit and the desk stable, and perform each drilling operation safely and efficiently. 3. Due to monitor color variations, there may be a slight color difference. Since the product is measured manually, there may be some errors.

Selected high-quality alloys and brazing technology enhance the product's high-temperature resistance and anti-friction performance. Diamond particles are tightly embedded in the base steel, facilitating cutting. The cutter body is made of high-quality base steel for effective protection against deformation. [DRILLING EFFECT] The diamond surface coating is treated by sintering, which effectively reduces resistance, friction, and heat. When using, hold the hole opener vertically, remove the drill bit after drilling the circular groove, and continue drilling. It can be water-cooled to ensure performance and lifespan. [PRECISE HOLE OPENING] The center guide drill bit has an auxiliary positioning function. While maintaining high concentricity, it easily locks the center of the hole to prevent drill bit deviation. It ensures uniform force and reduces vibration during drilling. It allows you to drill precise, round, clean, and smooth holes, providing a perfect opening and improved work quality. 【CHIP REMOVAL DESIGN】Diamond hole saws feature a U-shaped groove for fast cutting. Side chip removal holes allow for efficient and quick cleaning. They also facilitate the entry of cooling water, thus extending the hole saw's lifespan. 【WIDELY APPLICABLE】The diamond hole saw is suitable for a variety of hard materials, including porcelain, ceramic, granite, marble, masonry, concrete, glass, etc. Both dry and wet drilling are available to meet the needs of construction professionals and DIY enthusiasts.
