C.K Tools T3115 070 Punta per calcestruzzo 7 mm x 105 mm con attacco esagonale da 1/4"

Drilling into stone, masonry or concrete with a standard twist bit quickly dulls the cutting edge and can overheat the tool. The C.K Tools T3115 070 masonry drill bit solves this by pairing a carbide tip with a tough 40CR steel body, so you can bore clean holes in hard materials without destroying the bit.

Who is it for

Electricians, plumbers, HVAC technicians and serious DIYers who need to anchor into brick, block or stone. The 1/4" hex shank makes it especially useful for cordless impact drivers and quick-change chucks, letting you swap bits in seconds without a key.
