The hole saw is one of those products that can either make or break your day, par ticularly when using a masonry variation on materials like tiles, porcelain and stone. An inferior product won’t have the cutting power due to not enough diamond material on the teeth, producing dull and time-consuming cuts.
The Kango range of Diamond Pro hole saws features rapid removal slots, with an abundance of leverage points for fast plug removal, increasing productivity. In fact, in all our testing we didn’t experience a single stuck plug. The plug literally fell out on its own or came out with a single poke.
Even though we tested the hole saws with our 18V AEG hammer drill, you can opt for drill- or grinder-compatible arbors, giving great options in how you use the product.
Other features include the ability for either dry or wet cutting and a thin kerf design, which produces faster cuts and more of them per battery charge.
A high-quality alloy steel backer enhances durability and Kango’s world-leading diamond-retention techniques are said to produce unmatched saw lifespan.
TEST #1: DRY CUTTING TRAVERTINE TILES
Choosing to wet cut will definitely extend the life of a hole saw, but a dry cut will really test cutting quality and performance.
Our first cut was with the biggest of the hole saws: the 64mm.
This big bruiser did an exceptional job at the dry cuts through the 25mm Travertine tiles we sourced for the test. The cuts all looked great. Let’s be clear: I’m not a professional when it comes to cutting stone and tiles, so I was impressed with the results.
Our next dry cut was with the smallestoption, the 29mm hole saw. For this test we dropped down to a 10mm tile and again the results were excellent, with quick, clean and precise cuts.
TEST #2: WET CUTTING PORCELAIN TILES
We selected a mid-range sized hole saw for the harder porcelain tile, a considerably tougher test than the previous Travertine, and added the water and slowed down the cut.
We chose to take our time with this test, and it showed in the stunning results. The water worked to lubricate the cut as well as clean out the dust while keeping the saw teeth cool, and it produced crisp, clean-cut edgesand really showed the potential and ability of this range. It’s great to know that if you need to dry cut you can, but to prolong saw life and reduce the abrasion and friction on the diamond teeth I would say wet cutting is the way to go.
THE GOOD, THE BAD AND THE UGLY
The only ugly on this test was probably my terrible stone-cutting technique.
It’s been a long while since I’ve used a masonry hole saw. If I can get decent results, you tradies who really know what you’re doing and cut stone regularly will appreciate the features Kango has built into the Diamond Pro hole-saw range. The rapid removal slots worked well, and the design meant the plugs seemed to come out on their own. There was no wrestling trying to remove the plugs and the thin kerf didn’t overwork the drill, so there’ll be no burning through batteries while using the hole saws.
The diamond retention on the hole saw was evident on inspection after our testing. You could easily see and feel there was still plentyof bite left on the hole saws to rip through a pile more cuts.
Nice job on the new product range, Kango.
