Truvic 20mm Diamond Coated Hole Saw Tile Ceramic Glass Marble Core Drill Bit Tool

The primary purpose of purchasing this tool was to have a hole for the LPG hose on a 17 mm granite slab. Initially, I was skeptical about this tool considering reviews but gave it a try for the price point.•••••••••••••••••••🎁 INSIDE BOX•••••••••••••••••••1x tool1x plastic toolbox••••••••••••➕ PROS••••••••••••1. Good quality tool with smooth operation2. Can cut through up to 30 mm slab with home dia ~20mm3. Can be easily used with a drill machine (non-hammer mode)4. It would last for 8-10 holes (justified for the price, and most of the end-users won't cross that limit)5. Takes 2 to 3 mins at max to drill the hole••••••••••••➖ CONS••••••••••••1. Shaft for drill chuck is only 25 mm long2. Not suitable for professional usage•••••••••••••••••••⚙️ Operation•••••••••••••••••••1. Fix the tool to the drill chuck2. Add some water to the place you want to drill a hole3. With drill at full speed, gently touch the surface with the rotating tool4. Keep the drill stable, and you need not apply any pressure if drilling from top5. Keep adding water to cool the tool and contain dust (but be cautious of mud and dirty water, which will spread out at high rpm- you may create confined space with cardboard to contain it)••••••••••••••••🏆 VERDICT••••••••••••••••Overall a recommended tool for the said purpose, at a given price point (<200).

Worked as intended.Used to cut hole on granite for gas pipe installation.

It does the work. I drill a hard slab in kitchen and it did the job but took close to 20 minutes to finish.It is a good product if u are going to use at home.

I have seen a lot of negative review saying the drill bit is breaking or not functional etc. I ordered it any ways to give it a try.. It cuts granite smoothly... No issues at all...You have to start drilling in an angle first then slowly bring the drill machine perpendicular, do not apply to much pressure while drilling and keep pouring water while it's cutting the stone.....

I used this to drill hole for gas pipeline in granite. Good result. Worked fine. But i think it can be used once. Even then at this price it's fine.

Gud quality

I bought it for my aquarium drilling,8mm glass drilling with in one minute.
