Customer Questions & Answers

Can this be used on acrylic?

Im making a terrarium and I need a 3/8 dia hole every 6inches in an acrylic sheet.
Asked by: Nicco
Howdy Nicco, Usually a pilot drill and guide are provided to locate and center the hole saw. Coarse-tooth saws should be used for cutting Plexiglas acrylic sheet. The Plexiglas acrylic sheet should be cut halfway through, turned over, and the finishing cut made from the other side. When cutting sheet greater than 0.236 inches thick, a detergent/water lubricant and coolant should be used. A saw-cut hole is typically rough and often melted, requiring a post-finishing operation. Better quality holes can be achieved by machining with a router or circle cutter. I find a 3/8 bit that was titanium or carbide worked just fine as long as you drilled slower than usual. Happy drilling, Coach Dave

can this be used to put holes to plywood. spades are chipping on the edges

Asked by: Gopal
No. This bit is not made to cut through plywood. For this application, we recommend using one of our Hole Dozers™ for cutting through plywood.

Instructions located, in side packaging, where concise. Only required for on hole in one 12 x 18 Italian ceramic tile. Very minor chipping due to an inexperience operator, me. Very much worth the cost.

Rated 5 out of 5 by from Life Saver!! This bit is a little expensive for what i needed, but it got the job done. Went to my local Home Depot looking for something i could use to cut into granite countertop. I had purchased a countertop and undermount porcelain sink from another vender and it came with clips with anchors that needed to be inserted into the counter with epoxy but had no way to drill it. After about 5 mins of looking for something diamond tipped i came across this bit. Didnt want to spend this much for 4 holes but was better than the way i was told to install it. All i can say is use plenty of water from a spray bottle and go slow and let the tool do the work. After i got to the depth i wanted i took a small chisel and hammer and lightly tapped on the center plug and it broke free clean and didnt damage the top at all. First pic is of some practice holes i made on an extra peice of granite i had to make sure it would work, 2nd is after install

Rated 5 out of 5 by from drills holes through tile, porcelain, hardened steel bolts Bought this to drill through porcelain tile to mount my toilet flange to the plywood sub floor. The, stripped out a hardened steel engine head bolt. No other way to remove it. It took about 5 minutes off slow drilling and some oil for lubricant. Bit is still in great condition.
