Features Versatile Compatibility: Fits shaft diameter 6mm and chuck diameter 6mm, suitable for both drilling machines and pistol drills, providing adaptability for various tools and applications. Efficient Water : Easy loading and unloading, allowing water to enter from the hole opener, facilitating easy drainage of slag under water pressure, reducing friction, and maintaining the integrity of the hole edges. and Smooth Drilling: Ensures neat, smooth holes with no broken edges or tremors, enhancing the overall drilling quality and accuracy. Enhanced Performance: Minimal incision resistance results in increased opening speed, improving efficiency and productivity during drilling s. Multi-material Application: Suitable for drilling hard and brittle materials such as glass, ceramics, marble, and widely used in various industries including glass, ceramics, jade, and shells. Features: 1、Suitable for drilling machines (table drills) and pistol drills, and then with the hole opener 2、Easy to load and unload, because the joint between the water head and the water pipe, the water can enter from the hole opener (drill bit), and the slag generated inside the hole can be easily drained under the pressure of water, reducing the broken friction between the slag and the diamond and the inner wall of the base. 3、The holes are neat, smooth, and have no broken edges, and no tremor 4、Small incision resistance, increased opening speed 5、Easy to decorate after slotting and remove chips 6、Can be used for drilling hard and brittle materials such as glass, ceramics, marble, etc. 7、Widely used in glass, ceramics, jade, agate, shells, etc. Specification: Item Type: Water Nozzle Drill Chuck Material: Tungsten Steel Weight: 6x6 (164g) 6x10 (189g) Size: Approx. 10 x 4 x 4cm / 3.9 x 1.6 x 1.6in Package List: 1 x Water Nozzle Drill Chuck Package List 1 x Water Nozzle Drill Chuck
