Application: Wide application for porcelain ceramic tile granite marble stone masonry brick. Feature: 1. Dry or wet drilling. 2. Vacuum brazed technology provides much longer working life than electroplated technology. 3. High quality diamond grain provide fast and smooth drilling. 4. Minimizing any breakage and safe for operator. 5. Less chipping, minimizing breakage, less heat generation, better finish quality.

• Application: Dry or wet drilling holes in porcelain tile, ceramic, marble, quartz, granite, masonry, etc. Not recommend for drilling glass and wood.
• Recommended Machine: Hand drill, bench drill. General hand drill speed is 2000RPM-5000RPM. Ensure that the drilling speed is not less than 2000 RPM. The higher the speed, the longer the work life. Don't use the impact or hammer mode.
• Durable and Sturdy: Vacuum brazing processing technology make diamonds are more exposed; So that core drill bits are sharper and improve work efficiency. The average service life of vacuum brazed drill bits is 3-5 times that of electroplated tools.
• Good Effect: U-Grooves Design helps chip removal and improve the working efficiency of hole drilling. #40 sharp diamond, less debris and edge breakage on materials and better finishing effect.
