Choosing the right kind of core bits may not be obvious for everyone. Let us help.
Dry core bits, like the name suggests, can be used without water; while wet bits require water-cooling to operate. Using dry bits is convenient and more friendly to DIY users, but it is often not powerful enough to match the drilling power of wet core bits. Here we have put together a quick guideline to help you determine which bit to use depending on the target material, and equipment.
