1. What is Diamond Core Drilling?

Diamond Core Drilling is a form of drilling which employs a rotary drill with a diamond core tipped bit attached in order to drill the most accurate and quickest hole. Given that diamond is the hardest natural material in the world, this means that it is the perfect tip for drilling into a variety of base materials including concrete, steel and glass.

2. How is a diamond core bit made?

 BBTec uses an advanced sintering technology for the manufacturing of the new HiSpeed diamond core bits. Sintering is the process of forming a solid mass of material through heat and pressure without melting to the point of liquefaction. BBTec has developed a new advanced Sintering Technology called SinTec. The combination of SinTec Technology, the development of special bonds and the exclusive use of top-quality diamond crystals has resulted in a unique range of diamond core bits that guarantee an unparalleled drilling speed and long tool life in a wide range of materials.


3. What are the advantages of diamond core drilling over normal forms of drilling?

Diamond core drilling besides being faster and more effective than normal drilling, is far superior in producing high-quality and accurate holes in a safer manner with less noise and less dust production. Given the quality and toughness of the diamond tipped bit, the lifespan of a general bit will far exceed a normal drillbits. Core drilling will also allow the user to perform better in tough or difficult drilling environments given the flexibility and versatility of the tool.

4. How long will a diamond core bit last?

This is completely dependent on multiple variables when drilling including the quality or density of your drilling material, the amount of water you use while drilling, if the user is applying the correct amount of pressure while drilling, how often the specific bit is being used and the quality of the actual diamonds core bit itself. Luckily, ICCONS takes away all the guess work and makes it so easer to not only have the highest quality diamond tools and bits available but to help guide users on these variables and help increase the lifespan of the bits! One of the most useful BBTec Karat 180 features is the dual built in Motor Protection System. The Motor Overload Protection are 7 bright LED’s that visually aid the operation in maintaining optimal bit feed pressure thus preventing motor overload and increasing drilling performance. As well as this, the Pulse™ Electronic Motor Protection System physically alerts the operator of an approaching motor overload by varying the RPM rate up to 6 times before it shuts down automatically. The introduction of both these systems have resulted in increased machine and bit life and allows the operator to always achieve optimal drilling speed and efficiency. The BBTec Karat 180’s key features are unmatched when it comes to today’s core drilling market!


5. How do I correctly use a diamond core drill?

  • Assess the environment and check for hazards
  • Make sure all relevant PPE is on
  • Attach the correct bit size to the drill and make sure the correct gearing setting is chosen, which will allow for the best drilling performance
  • Confirm your drilling setup is ready to go – whether it is attaching the stand to the ground, connecting water source, angling your drilling route correctly etc
  • Use the Karat soft-start feature to align your bit with your drilling route most accurately
  • Make sure to keep your core drill straight while you drill and remember to go slow when you hit tough materials like rebar
  • Take the core drill out from the base material when finished and remove the concrete core from inside the core bit
