sourcing map Diamond drill bit for glass hole saw with center positioning bit for glass, ceramic, porcelain, tile 30 mm

1. Smooth and finished, reducing cutting resistance and drilling pressure, improving sharpness and water lubrication efficiency.

2. Create clean, precise holes with virtually no chipping in minutes. The pilot drill bit in the center allows you to cut precise holes.

3. The drill bit is zinc-plated, which offers high corrosion resistance and maximizes tool life. Ideal for drilling stone or ceramic, significantly extending the drill bit's lifespan.

4. The diamond drill bit features clearance holes, which facilitate the entry of cooling water, allowing certain chips and other particles to escape more easily from the drilled hole. This simplifies the drilling process.

5. Suitable for processing stone, ceramic tiles, glass, granite, etc. Ideal for use with electric drills.

Information

Types of diamond treatment on drill bits include sintering, electroplating, or brazing. Electroplated and brazed diamonds are surface-coated and bonded to the cutting edge. The cutting edge dulls instantly when the diamond detaches. Sintered diamond cutting edges contain diamond particles from the inside out to ensure the edge remains sharp. Sintered diamonds have sharpening properties, but galvanized or brazed diamonds cannot be sharpened.

Diamond Drill Bits

Produce clean, precise holes in minutes with little or no chippingThe pilot drill in the center helps cut precise holes.

Long Lifespan

White zinc plating on the tips for good corrosion resistance. Excellent for drilling holes in wood or ceramic and significantly extends the drill bit's life.

Clearance Hole

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

Tips:

• Start your hole diagonally, make a circular cut, and keep the drill straight.
• Always use water lubrication when operating drill bits.
• Low drilling pressure and increased use of water lubrication will extend the drill bit's life.
• Not suitable for use on concrete or for depths greater than approximately 1.2 cm.

 

Many Uses:

Widely used for cutting precise holes in glass, ceramic, porcelain, ceramic tiles, porcelain tiles, limestone, slate, marble, aluminous stone, and fiberglass. Not suitable for drilling tempered glass, plastic, and wood.

Reduced drilling speeds, low drilling pressure, and increased use of water lubrication will prolong drill bit life. Works best with an electric drill (not included here).
