Amtech F1210 50mm (2") Core drill

Product Information

With everything assembled it’s time to start drilling your hole. Position the tip of the guide drill on your drilling mark and start the drill slowly, increasing speed slightly until the pilot drill starts biting into the wall. At this point you will only have around half an inch or so to drill through so take your time and once done you will be left with a nice neat and clean hole. In general, the bigger the hole, the more expensive it’ll be. However, you can also expect to pay less per hole if you’re getting a lot of holes done as opposed to just a few.

Most domestic use diamond core cutters will always have a removable guiding drill bit which acts as a pilot hole to guide the core drill.As always at DIY Doctor we advise the use of purpose built tools for DIY use. Safety must always come first. Wear the appropriate safety equipment, gloves, dust masks and eye protection at all times. Due to the amount of heat created during the drilling process it is necessary to keep diamond core bits as cool as possible to prevent unnecessary damage to the cutting teeth to a minimum. If the surface of the cutting teeth are subjected to too much heat the metal encasing them melts covering the diamonds and reducing cutting efficiency. If this happens the drill bit then needs to be “redressed” to expose the diamonds once more.

Keep drilling until the core drill teeth hit the surface of the wall. You will feel them bite once they do. In the majority of domestic cases the largest hole you will need to drill will probably be around 6 inches in diameter through a standard cavity wall which will be around 300mm in depth. For anything up to this size a dry cutting diamond core bit will be more than up to the job.CLEAN AND PRECISE CUTS - Enjoy clean and accurate drilling with our segmented design, providing outstanding cutting performance and minimizing the need for an additional filling.
