About this item
  • Drill Bit Design: The drill bits are made of diamond grains with wax lubricants, which melt during dry drilling and cool the cutting surface. Water can serve as an additional coolant to prevent diamond loss and extend the lifespan of drill bits
  • Strong Compatibility: The round shank design of diamond tipped drill bit is compatible with machines, such as electric drills. The marking line on the side can assist in marking the drilling depth and improve the efficiency of drilling
  • Easy To Carry And Use: Diamond drill bits for porcelain tile are packaged in paper boxes and are easy to store. Five sizes of drill bits are more convenient for drilling various materials
  • Hard Material Drilling: Hard diamond drill bits are suitable for drilling on various hard materials, such as tiles, stones, and other hard surfaces, but not suitable for drilling on wood. The side groove on the drill bit helps to drill quickly and smoothly, removing debris
  • Package Includes: 5pcs 6mm/1/4 inch, 1pcs 8mm/5/16 inch, 1pcs 10mm/3/8 inch, 1pcs 12mm/1/2 inch diamond drill bits, and 1pcs 6mm/1/4 inch carbide drill bit, many sizes bits can meet daily drilling needs

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
