NEO TOOLS 55-319 sada diamantových korunkových vrtákov, 5-dielna (6, 8, 10, 12, 16 mm) s kufrom

Cutting clean holes in tile, porcelain, or stone often means risking cracks and wasted material. The NEO TOOLS 55-319 diamond hole saw set gives you five common diameters—6, 8, 10, 12, and 16 mm—so you can drill precise openings for pipes, anchors, or fixtures without chipping the surface. Each bit uses industrial diamond grit bonded to a high-carbon steel body, and the hexagonal shank fits standard drill chucks. Use water for cooling and longer bit life. A plastic case keeps the set organized on the job or in the workshop.

Why choose it

Diamond grit cuts through hard, brittle materials that standard bits cannot handle. The set covers the most requested hole sizes for plumbing and electrical work, and the hexagonal shank prevents slipping under load. Wet drilling keeps the bit cool, extending its service life and producing cleaner edges. With five sizes in one case, you avoid buying individual bits and always have the right diameter at hand.

Ideal use cases

• Drilling holes in ceramic wall and floor tiles for pipe penetrations
• Creating openings in porcelain tiles for shower fixtures and faucets
• Cutting glass, marble, granite, and stone for decorative or functional purposes
• Professional tile setters, plumbers, electricians, and serious DIYers

Good to know

Always use water as a coolant and lubricant when drilling—this reduces friction, prevents overheating, and prolongs bit life. Start the hole at a slight angle to create a guide groove, then straighten the drill. Apply steady, moderate pressure; let the diamond grit do the work. The bits are not intended for metal, wood, or concrete. Store them in the provided case to protect the diamond coating from damage.
