This Klein Tools Hole Cutter will be used primarily for conduit as I am rewiring my workshop and many of the electrical boxes on hand do not have knockouts.The 7/8 inch size is needed for the 1/2 inch conduit. There are many very useful features found in this hole cutter. The pilot hole drill bit is surrounded by a spring. My old hole cutter required pliers to pry out the metal piece but the spring in the Klein cutter pops the piece out. The pilot hole bit is replaceable and the allen wrench for the screw is included. The cutters are very sharp and did not even get hot after drilling a test hole. Another great feature is the flange that keeps the cutter from passing through the hole. A small length of tubing covers the pilot bit when in storage. A very nice reclosable container that stores the hole cutter and allen wrench is also included.

The Klein carbide hole saw is a top quality tool. It is the best cutting hole saw I have ever used. It easily cuts through steel and didn’t seem to dull the teeth. Included is a plastic storage container along with a hex wrench to replace the drill bit. Also the saw has a spring mounted inside to discharge the drilled core. This hole saw will last a long time and provide good service.

The Klein tools 7/8 inch carbide tipped hole cutter looks like a quality made tool. It can cut precise holes in stainless steel, mild steel, iron plate, copper or brass sheet up to 3/16 thick. The pilot bit can be replaced and it comes with the Allen key. The drill bit is meant to be used only in the forward cutting direction, so not in reverse. This hole cutter should last for quite a few holes.

The KLEIN tool carbide hole cutter is a great tool. It is made from heavy duty materials was very sharp. The cutter bit through the material very easily leaving a clean hole. I needed a metal support brace where a pipe ran and the bit worked great leaving a clean hole for the pipe. I would highly recommend this and other size bits for DIY’ers to professional workers.

I used the carbide hole cutter to help create some indents for cabinet hardware that I was putting in. I also used it to cut some holes in wood where I wanted to line up to 2 by 4s in order to create some holders for my tools that attach to my workbench. Really easy to use with a drill; and overall pretty happy with the consistency in the holes. Easy to clean

This is a nice drill bit, especially when you get into bigger diameter holes. It has a inner bit that helps to keep it centered and stable. It also has a spring around the inner bit to kick off the piece of metal that gets trapped between both bits to save a lot of time if you have a lot of holes to drill. It seems to be very well made and it doesn’t take long to drill with this bit.

The Klien Tools hole saw is a quality piece. The cutting blades are carbide tipped for wear resistance and long life. This cutter is for sheet metal up to 3/16 and there is a flange that keeps you from cutting too deep. The shank is 3/8 so it will fit most standard drills. There is a pilot bit that can be moved or replaced with the loosening of a set screw, allen wrench included. The tool also comes with Klien Tools warranty. I gave it a good rating because of the cost.

Welcome to the strange world of electrical parts sizes. A 1/2 inch thinwall conduit (EMT) actually measures about 5/8 inch inside and just under 3/4 OD. The fitting for that conduit fits into a steel electrical box with a “1/2 inch knockout” hole which actually measures 7/8- inch. That’s where this wonderful drill bit (actually a hole cutter) comes in. Quite often the knockout locations on a larger piece of electrical equipment such as a circuit breaker panel aren’t where you need an opening. Perhaps your wiring or conduit would work better and be cleaner if it entered the box in a different location. It is usually allowable to drill additional holes in these panels as long as they don’t interfere with other components or interior parts and it is done in a “workmanlike manor”. Actually, many electrical panels don’t even come with knockouts at all, and the electrician is expected to cut them in where needed.This Klein 7/8 hole cutter is designed for the 1/2-inch EMT fittings, NM cable clamps and other fittings that are designed to fit the “1/2-inch” hole into electrical boxes and enclosures. The best part is that it works great. It is carbide-tipped, so it works fast and cuts a clean precise hole, unlike hole saws. Little if any filing is needed to remove burrs. It also works well for drilling holes in steel studs, since often there are no factory holes in the studs where you need to run conduitThe cutter portion of this tool is removable from the pilot bit in case it needs replacement or sharpening, and an allen wrench is also included for that purpose. It is also designed with a spring around the pilot bit to pop out the center slug. While it comes with a paper giving recommended speeds for various metals, and a plastic display box, I would have liked to see a box that was more durable for long-term use that would protect it, with the speed chart permanently attached to the box. I take good care of my tools and expect them to last a long time, and a good storage case shouldn’t be too much to ask for the price. I found this cutter to be well designed, and should be a real time-saver as opposed to a traditional knock-out set. I suggest using it like a traditional hole saw and drilling straight to avoid binding, and don’t exceed the recommended speed. For most users with battery drills this will seem very slow, but I suspect going too fast would damage the cutter and create an undesirable cut.
