Questions about this product

Will this fit my drill or angle grinder?: It uses a universal M14 thread, so it attaches to most standard drills and angle grinders with that fitting. You may need an M14 adapter if your tool has a regular chuck. The maker recommends a high-torque drill for hard materials.
What hole sizes does this kit cover?: The bits run from 20mm up to 110mm. Common increments include sizes like 25, 32, 50, 68, 76, and 102mm. That range covers most plumbing, electrical, and faucet holes in tile or stone.
Do I need to use water when drilling?: Yes, wet drilling is recommended. Running water cools the diamond grit and clears dust, which keeps the bit cutting cleanly and extends its life. Drilling dry on porcelain or granite can overheat and damage the segments.
