Diamond drill bit for glass/ceramic hole saws – 40 mm with centering drill bit, ideal for tiles and porcelain

• Features: Suitable for stone, tile, ceramic, glass, etc. The center-positioning drill bit helps cut precise holes.

• Long service life: Reduced drilling speed, low drilling pressure, and increased use of water lubrication will extend the drill bit's life.

• Clearance hole: Diamond drill bits with a clearance hole facilitate the entry of cooling water and the removal of drilling chips. This makes the drilling process easier.

• Clean and smooth cut: The diamond hole saw creates smooth, high-precision cuts without broken edges. The white zinc plating on the tips maximizes tool life with excellent corrosion resistance.

• Tips: Please use at low drilling speed and pressure. Always work with coolant (water) when drilling. Not suitable for drilling tempered glass, plastic, or wood.

Product Description:

1. Smooth and precise finish to lower cutting resistance and drilling pressure, increasing sharpness and the effectiveness of water lubrication.

2. Produces clean, accurate holes in minutes with little to no chipping. The center-positioning drill bit helps cut precise holes.

3. White zinc plating on the bits maximizes tool life with high corrosion resistance. Ideal for drilling holes in glass or ceramic and significantly extends drill bit life.

4. Diamond drill bits with a clearance hole facilitate the entry of cooling water and the removal of chips and other drilling particles. Makes the drilling process easier.

5. Suitable for stone, tile, ceramic, glass, etc. Works best with a power drill (except for this item). Note:

1. Always use lubrication (water) when operating the drill bits.

2. Low drilling pressure and increased use of water lubrication will prolong the drill bit's life.

3. Not suitable for use in concrete or for depths greater than approximately 1.27 cm.
