What Customers Are Saying
This diamond-coated drill bit performs well for drilling clean holes through ceramic, glass, and tile materials, especially when used with water to keep the bit cool. However, it can be challenging to start the hole and keep the bit steady, particularly on porcelain tiles. Users recommend starting the hole at an angle, gradually straightening the bit as it cuts, and using a low drill speed. The bit may wear down quickly, especially on thicker or harder materials, so it's best suited for light to moderate use.

Would RecommendStarts fairly easily at higher speed at an angle. Makes a clean hole with very little chipping. Very fast to complete the cut. No noticeable wear on the bit after drilling. Wet drilling is faster than dry. Overall, a very good drill bit for ceramics.

Not the best option
Would Not RecommendDifficult to start cleanly, bit skates over the surface. Center hole fills with material and slows drilling down. Not very fast even at speeds higher than recommended. For this size hole, this bit is harder to use than a single point bit. Hole was clean with little chipping.
Difficult bit
Would Not RecommendTried the quick change ¼” shank but preferred to insert directly into drill chuck. Bit seemed to work much better wet than dry. Slotted for material extraction, but center of bit fills up, particularly if wet. For a ¼” hole, this bit was very hard to start and skated easily on tile. Packaging says to operate at maximum speed of 400 rpm, but needs to operate much faster to drill in a reasonable time. Appears to be durable with no signs of wear after one hole.

Fast clean cuts
Would RecommendDoes cobalt wholesale makes fast clean cuts. The one and three eights inch size makes it perfect for cutting through tile, ceramic and so forth for installing inch and a quarter waterlines for drains for vanities . It made a fast clean cut With no cracking or chipping of the ceramic tile. I particularly like the large clean outs on the sides that you can simply stick a screwdriver in and knock out the plug that you just cut. I have always had great success with Kobalt tools And this is no di...
Great
Would RecommendThis works great for cutting holes in boards and timber! Wish it had a pilot cutter as well though! It’s Kobalt so it will last a lifetime! Fits any drill and super sharp! Definitely recommend this tool for your toolbox!

Superb Quality
Would RecommendThis saw bit is a great quality product you expect. Although I did not have a piece of granite, marble, ect to use it on, it will work like a dream when that time comes around! Very sturdy construction and well made. When I get new countertops put in the kitchen, this should be the perfect size for making holes for kitchen faucets. It can be used on dry or wet applications.

Great hole saw for tile
Would RecommendI wasn’t sure what to expect with this. I’m used to having an arbor to make sure my hole is where I want it. I soon figured out the trick is to start an edge then straight down. It cut extremely well. Did not chip the edges.

Cuts well
Would RecommendThis one was a little bit of a challenge. Being only 1/4”, it’s not as easy to start it. It wants to travel on you. If you’re able to hold it still enough for the edge to start, you will be fine. Like the others, the edges were clear of chipping, and smooth.
