【Multiple Diameters】In addition to the 5, 6, 8, 10, and 12 mm tile drill bits, you also get a 6 mm carbide drill bit. This saves you the hassle of drilling with a diamond drill bit and allows you to drill holes even more precisely and easily.

【Unique Dry Drilling Design】Inner wax provides cooling. Our diamond-tipped drill bits have built-in wax cores that automatically absorb and dissipate heat while working. Dry drilling produces no water and reduces environmental pollution.

【Multiple Uses】Porcelain tile drill bits, ideal for drilling clean holes in hard materials such as tiles, porcelain, granite, ceramics, glass, mirrors, stone, and brick. Note: Not for wood, metal, or plastic.

【Compatible Round Rods】The glass drill bits feature a round shank and are compatible with most machines, such as hand drills, angle grinders, and bench drills. Side grooves help remove debris and drill holes smoothly and quickly. The depth marking is also useful for certain projects.

【High-Quality Materials】The drill bit body with vacuum-brazed diamond technology offers very high efficiency, cuts faster, and lasts longer.

6-piece dry diamond drill bit set - 5, 6, 8, 10, 12 mm, and 6 mm carbide drill bits. Ideal for drilling clean holes in hard materials.

High-quality, high-temperature-resistant diamond grit for efficient drilling. Filled with cooling wax, suitable for dry drilling.

No cooling is required during drilling because the drill bits are equipped with cooling wax inside. However, it can extend the service life of the drill bits.

How to use?

1. Install the hole punch bit on the hand drill for use.

2. The electric drill keeps the speed high and tilts 45° throughout the process to obtain the half-moon groove.

3. After drilling the positioning groove, place the electric drill vertically, shake it slowly in one direction, and drill.

4. Drilling completed.

It is important to rotate slightly when drilling!

This ensures optimal drilling results.

Note
