What Customers Are Saying
Customers praise the drill bit for cutting cleanly through tile, glass, and porcelain without chipping, with most reporting excellent results on demanding projects. Many highlight durability under proper use, noting minimal wear after multiple holes when water cooling is applied. However, some report premature failure including bent shafts or twisting after few uses. Success depends heavily on technique—starting at 45-degree angles with low RPMs and steady pressure yields consistent performance. Despite some quality concerns, most customers who followed proper methods found it reliable and plan future use.

Don’t bother with this tool
Would Not RecommendJunk. Bought this to drill holes in porcelain tile. Less than halfway thru the first hole the bit had bent enough to make it useless. Took a long time to drill as well. Got a Lenox diamond bit and it went thru the next 3 holes like it was wood. Get the brand name!
