In the field of drilling and processing high-strength materials, the selection of the right tool can have a significant impact on efficiency, quality and longevity. This text details the distinctions between conventional and diamond core bits, as well as the reasons why the latter are preferred in demanding projects.
Material and Composition

– Conventional core bits: Generally made of high speed steel (HSS) or tungsten carbide, they are optimal for drilling low to medium hardness materials such as wood, plastics and non-ferrous metals.
– Diamond core bits: Incorporate diamond powder on their surface, which gives them exceptional hardness and resistance properties. They are suitable for cutting very hard materials such as concrete, granite, marble, glass or ceramics.
Performance and Accuracy

– Conventional crowns: They perform adequately in standard applications, but tend to wear quickly when used on hard materials, which can compromise cutting accuracy.
– Diamond core bits: They provide superior performance thanks to their ability to make precise, fine cuts in even the toughest materials. In addition, they generate less vibration, which reduces the risk of damage to the material being processed.
3. Durability

– Conventional crowns: They have a limited service life in high-demanding projects, as heat and friction cause rapid wear.
– Diamond core bits: Their resistance to heat and wear allows them to maintain their functionality for a considerably long period of time, making them a sustainable investment for professionals and companies.
4. Applications

– Conventional crowns: They are an economically viable option for simple tasks or in easy-to-handle materials. They are commonly used in do-it-yourself projects or in low-demand applications.
– Diamond core bits: These are essential tools in sectors such as construction, mining and natural stone processing, where it is necessary to drill hard materials with high precision.
Which tool to use in your project?
If your work involves low to medium hardness materials and you require an economical solution, conventional core bits may be suitable. However, for requirements of precision, durability and optimized performance in demanding materials, diamond core bits are the most recommended option.
