In demolition projects, the Wet Concrete Core Bit is a valuable asset. Its ability to drill through concrete and other masonry materials with ease makes it an essential tool for efficient demolition.

Our wet diamond core bits are tailored for wet drilling tasks in concrete, brick, sandstone, limestone, and various masonry materials. Designed to be paired with water, they efficiently dissipate heat, minimize dust, and prolong bits life by reducing friction. These bits excel in drilling large holes or penetrating dense or reinforced materials, offering optimal performance and longevity.

While they provide mid-grade performance, our wet diamond core bits offer exceptional value at a lower price point compared to high-end alternatives. Despite lasting half as long as premium bits , they enable customers to drill the same distance for half the cost, ensuring cost-effectiveness without compromising quality. However, it's essential to select the correct bits size and type for the task and adhere to manufacturer instructions for optimal results and longevity.

It's crucial to note that while our wet core drill bits are primarily designed for concrete, they can handle certain types of rock, albeit at the expense of reduced bit life. Using them on materials beyond their primary scope is at the user's discretion and not covered under our standard policy. For faster coring and extended bit life, opt for wet core drill bits with high diamond concentration and superior quality, suitable for wet drilling in concrete, masonry, sandstone, limestone, and similar materials, including those with light steel reinforcement.

FAQ

Q: What speed do you need to drill a diamond core?

A peripheral speed of 2.7 to 4.7 metres/second (9 to 15.5 feet/second) measured on the outside diameter of the bit crown will often provide an acceptable rate of penetration (ROP).

Q: How to sharpen a diamond core drill bit?

Pour into kerf a thick (1/4") layer of silica sand, the coarser the better. Resume coring for approximately 3 to 5 minutes with very little water and at a lower RPM if possible. Gradually increase water flow to flush sand from kerf. Repeat as needed.

Q: Will a diamond core bit cut through metal?

Diamond drills can cut through almost all materials, including some of the toughest materials such as concrete, metal, and glass.

Q: Which is stronger, carbide or diamond?

Diamonds remain the most scratch-resistant material known to humanity. Metals like titanium are far less scratch-resistant, and even extremely hard ceramics or tungsten carbide cannot compete with diamonds in terms of hardness or scratch-resistance.
