TCT Core drills

[Scoby_Beasley]

Do you use these on hammer or rotary action ? ?
Used mine on rotary and took ages (Mind, me 15yr old B&D hammer drill has told me it's time to retire. Good excuse for a Bosch sds+ eh ??)

Rotary only. Can cause a lot of damage to core drill otherwise.

Scoby, TCT cutters are good, but you do need at least a 750W drill to be effective, and that is only on a 100mm cutter.

If you increase the cutter to 125mm or 150mm, then you really do need a 1000W or better.

We have a 1350W Bosch that is designed for core drilling, even that struggles occasionaly with the big cutters, depending on the material being cut.
