TCT Core Drills (12 mm – 130 mm): A Powerful Drilling Solution in Hard Materials

Core drills are special cutters used for drilling by removing material in a ring. They are also known as annular cutters. Because they cut a ring rather than the whole hole, there is no need to turn all the material into chips, which makes it possible to produce large holes with modest power. They also drill straight into solid material without a pilot hole. In steel structure work in particular, this type of cutter is preferred both to save time and to keep operator fatigue down.

One important element to use with these cutters is a suitable coolant. Soluble cutting oil can be an ideal option for improving cutting efficiency. Soluble oil is prepared by mixing 1 litre of soluble oil thoroughly with a large carboy of water. Neat cutting oil can also be used as a coolant, but that option can be more expensive and is not easily cleaned off after drilling.

The TCT core drill is ideal for drilling hard materials such as ST52 and Hardox. It also drills stainless steel successfully. These cutters are harder and more durable than HSS cutters and should be used on harder materials. TCT cutters can be resharpened at most three times, which means the number of regrinds is limited. Although they are less often chosen because of their price and limited regrinds, they are essential cutters for hard materials and for special applications such as railway track.

In short, TCT core drills offer an indispensable solution for powerful, effective drilling in hard materials. These special cutters are widely used across different applications in construction and industry. With the right coolant and the right cutter, you can get the best from magnetic core drilling.
