8 Things You Need to Know About Diamond Core Drilling

8 Things You Need to Know About Diamond Core Drilling

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

6. What are some key features of the BBTec Core Drill vs Other Core Drills?

  • LED Motor Overload Protection System with latest generation RGB LED’s
  • 2400W motor with Pulse™ Electronic Motor Protection
  • Redesigned mechanical safety clutch manufactured from new special steel composition

Customer Testimonials

“As a professional engineer with over 10 years industry experience, I have been recommending the use of ICCONS products since first learning of them back in 2017. What makes ICCONS products great is their technical design specifications. The engineering team at ICCONS has gone above and beyond to develop easy to read product manuals, which makes specifying the right product for the job very straight forward. They have also developed free design software for peace of mind. I rest easy knowing ICCONS regularly put their products to the test and perform.   If you’re an engineer, whether it be as a designer or hands on in the field, you will find the detail and ease of use of ICCONS a breath of fresh air. The information is easy to find, easy to use and complies to Australian Standards.”

Steven, Raw Worx
Customer testimonial

“We really loved the Structnail Gripshank Supersharpy as we saved a lot of time compared to the traditional way of screwing the boards on, but the biggest time saving comes from the head of the nail - it doesn’t buff up the board like a screw does, so the finished product looks so much better and basically no sanding and patching before painting compared to screwing it. The finished product looks amazing and we are really happy with it.”

Michael, Cardo Constructions
Customer testimonial

“We purchased the B+BTec core drilling equipment for a large job at Crown Casino and were very impressed with the performance of this product and the auto-feed unit was a dream. The speed at which the B+BTec core barrels cut through steel reinforcement was amazing. The team at ICCONS were fantastic to deal with in assisting with any roadblocks that we encountered with the job.”
