Diamond Core Drill bit- Changing the face of drilling industry by Mark Bruddy
Did you know that conventional, efficient diamond core drill , capable of a far wider range of applications than the original versions, have replaced the early traditional core bits? Today architects, engineers, concrete contractors and government officials can take advantage of these advances in technology by employing specialized drilling contractor who use diamond cutting techniques in the construction industry.
The specialized drilling contractors who perform concrete sawing and drilling services are experts in their field. They can recommend the best techniques and equipment for the most cost-effective cutting and are better prepared to bring projects on time and within budget. In addition, they have the training and experience to select the best sawing and drilling procedures to employ at any stage of the project. Moreover, these contractors know which types and sizes of concrete saw blades, core drill bits and equipment are best for the application, as well as have a comprehensive understanding of working clearance, disposal or other construction site issues.
Concrete cutting advantage
Knowledgeable contractors recommend and use diamond core drill bits because they can provide significant cost advantages over conventional drill bits. These advantages vary depending on the project, but include reduced downtime, precision cutting, maintenance of structural integrity, reduced noise, dust and debris, limited-access cutting, and the ability to cut heavily reinforced concrete. These advantages have revolutionized the concrete cutting industry.
Reduced fatigue, improved safety, and greater efficiency
The drill bit advances itself into the work material similar to a screw, eliminating the need to apply additional force. This unique technology greatly improves the safety and efficiency of handheld drilling while reducing operator fatigue, making it ideal for high-volume and heavy-duty construction applications.
Core Drilling
Core bits used by cutting contractors vary depending upon the application and job site requirements. Core drilling techniques are used when precise, circular cuts are needed. Holes of almost any diameter are easily drilled to make openings for plumbing, electrical and HVAC installations.
Core drilling is also commonly used to create holes for routing cables or placing anchoring bolts, installing load carrying devices or dowel bars, or for concrete sample analysis. Core drills can be operated in any orientation, vertical or horizontal. Core drill machines can be powered by electric, hydraulic or air power sources.
Materials and/or coatings are appropriate for the core bit
The drill bit can be made of typical materials such as oil hardened tool steel, cobalt steel, high-speed steel, or carbide. Coatings such as diamond, titanium nitride, titanium aluminum nitride, titanium carbon nitride, and others can be added to extend the life of the bit and provide heat resistance and lubrication.
Considering the benefits that newly designed diamond core drill bits can deliver, it is interesting to know that many architects, engineers, concrete contractors and government officials have actually embraced the diamond core bits quite passionately.
