Accordingly, when meeting end users they all tell us once having experienced the ProFit system they’d never again want to do without. Something we’re suitably proud of! It'd be good to get one of the multi-purpose bits for down lights and things like that. But yeah. So yeah. Pro-Fit Hole Saws. I'd probably try them out if you're ever thinking of a new hole saw set or just because they're easy to use. There are two centre drills 8mm for up to 32mm diameter holesaws and a 10mm HSS Centre drill for sizes greater than 33mm. A hole enlarging arbor is also included. Lots of space in the case for additional holesaws. Pro-Fit® tungsten carbide tipped TCT holesaws are perfect for plumbers, chippies and electricians. These TCT holesaws are the correct product for the job. Bi-metal holesaws are really designed for cutting through metal. In 2021 Pro-Fit hole saws are exclusively available from merchants which are part of the National Buying Group NBG Partners and online from Monument Masters.

A. The 8mm centre drill fits holesaws from 16mm to 32mm. The 10mm centre drill fits holesaws from 33mm to 330mm. The only downside I can see with this is that the drill bits, where they're all built in, means you have to buy a whole thing if your drill bit goes blunt. Worst case, you just pilot and use this as a guide, but still something to think about.

I'm going to put it to a test on this bit of timber now. Obviously, you'd never drill a hole this size in a bit of timber this size, unless it wasn't structural. If I have to give you a negative point and it is only a small one, it's that this piece doesn't have an interchangeable drill bit. So if it gets blunt, you are into sharpening it. If you haven't got that piece, then you are going to be looking at buying a new arbour shall we say. But as long as you're careful, you know what you're drilling through, I don't see that as a problem really. Great piece of kit. Love it. I shall be putting this into my toolbox and using it as much as possible. It comes in a nice little box. There's two there for a starter kit.

Okay, go from the other side. Pull it out. And that's the difference when you go from one side to the other. You don't get the damage.It's handy to note that the higher the TPI, the less likely the hole saw is to tear your workpiece. The lower the TPI, the more likely this is. We typically advise that 1-4 teeth per inch equals a low TPI, whilst 10+ teeth per inch equals a high TPI. Well that's pretty impressive, actually. The difference between this one and these is you've only got one cutting edge, one tungsten tip there, and that's what's doing the work against all these pulling away at the same time. I do believe that sometimes when you're cutting holes, or it's happened to us, and you've measured up and you're slightly out of line, what you find is that you're trying to cut a bigger hole here. You can try and do it with one of these, but you tend to skate when you get off the centre, so your hole goes out of line. Each and every day professional end users -around the globe- experience the fact that our tools work faster, last longer and basically make life a whole lot easier. In addition they can rely on ProFit making the widest range of diameters available bar none. Hi, my name's Ian Winnard, and I'm from Ian Winnard and Son Heating and Plumbing. Today, we're going to be testing a new piece of kit that's been sent out to us from the Tool Talk testing kit, courtesy of Harrison. We'll just zoom in and show you this that's arrived in the post. It's got this little bar there. It's got the Pro-Fit name on it. Quite a substantial little piece of kit. And a series of cutters, there's two cutters here. The first cutter is a Pro-Fit, and it's 20 millimetres, so be okay for 15 mm pipe. The other one they've sent out is 25 mm, so you could put a 22 mm pipe through cupboards or units or even floors with this type of stuff.

Q. When cutting thru thin plywood on a [kitchen] cabinet with a painted finish, what side do I start ? There are different types of hole saws and they generally range in size between 14mm and 210mm in diameter. Holes below this size can usually be achieved using a standard drill bit, while larger holes will generally require alternative cutting methods. This is the starter kit, and what's in the starter kit is a 32mm whole saw set and a 20mm. There are Two drill bits. One is for the bigger, it goes on like that. And this one's for the smaller one, that's it simple as that. Obviously, again, the 10 is for these bigger size hole saws. I assume the 8 probably goes up to 25, maybe 32. And then above that, obviously, you do want a bigger shank anyway.

Hole Saws HM Multi Purpose from PROFIT

As I say, I've been using these a couple of weeks. As you can see here, I've already drilled a couple of holes in this wet bit of three by two, and it flies through. I can do another demonstration. Straight through. As you can see, the plug is in the holesaw. You literally just press the button in, pull the holesaw towards you, that leaves the plug there. You can twist it off the drill bit and that's the plug out. They come in different sizes. You can get several kits, but the one that I've got here is the 38mm. I've got a scaffold board and an old bit of kitchen. Cuts through it like a hot knife through butter. Easy. Easy to clean out. Straight out. Give it a little clean. Easy as that. It cuts though stuff really easily. Kitchen cupboard flew through it. Pro-Fit. Great bit of kit. Brilliant. I'm impressed with the way that this cut through this. In fact, it's so good, I want to give it another go, because I want to see if the piece of wood that I cut out stays inside.
