What Width Diamond Blade Do I Need?

Generally speaking, faster, more efficient cuts are made using the narrowest kerf blade.

Why Do They Make Wider Blades?

As blade diameters increase, so must the thickness of the steel cores (blanks) that the diamond segments are attached to. When using a 36″ diamond blade for cutting 15″ deep, the blade is generally at least .175″ wide. Professional cutters often prefer to save time and money by starting the cuts with a smaller, less flexible, more cost effective blade, like an 18″ or a 24″ blade. When doing so, either of these blades must be at least .175″ wide. Also, when cutting with a diamond chain saw or Partner Ring Saw, money can often be saved when by cutting to the 4″ or 5″ first with a hand held chop saw and a blade that is at least as wide as the chain or the ring blade. We have these blades in stock at Diamond Tool. You get the idea!

Can Dry Blades Be Used Wet?

Yes, of course, and we will see that more and more as we attempt to hold down the dust when cutting dry. Just because you can cut dry does not mean you should.

Why Spend More Money On A Blade?

That is a great question! We are glad you asked. As a norm, the difference in the cost of manufacturing the least expensive dry diamond blade and the most expensive one is determined primarily by the quality and quantity of the diamond used. The diamonds can be thought of as Good, Better, and Best, while the quantities vary substantially. Because there are ten to twelve steps in producing one of these blades, adding six or ten times to the cost, quality and quantity of diamonds will only increase your cost by two or three times. The good news is, that your life and speed can increase by four to six times for the small extra investment up front. Regardless of price, the bond and the “way the blade is made” also have significant impact on the speed of cutting and life of the blade. Dealing with Diamond Tool ensures that you will get the correct blade for the conditions you face.

Is Segment Height A Measurement Of Blade Quality & Life?

Sometimes yes, and often, no! Telemarketers have become notorious for importing blades from the Pacific Rim made with higher segment heights. All the while, some companies boast of meaningless and unverifiable diamond concentration percentage. One of the best Professional Wet Asphalt blades we ever tested had one of the lowest segment heights. Go figure. Now back to the “yes” part. Reputable manufacturers like Diamond Products (Core Cut brand), list increasing segment heights as an indication of increasing quality and life in their Pro Wet Blade series. Confused? Pick a distributor that you trust (hopefully us), and ask for a recommendation as to the best blade for your project and budget.

How Do We Anchor Our Core Drilling Rig For Maximum Performance?

Three general methods are used in order of frequency of use in the industry.

1. Mechanical Anchoring – Drop in anchors through the anchor slot and a piece of threaded rod. 1/2″ are most common.

2. Jack Poling – Use where typical ceiling heights are encountered of steel or concrete, that are not too high. Not generally used for holes over 6″ in diameter.

3. Vacuuming – used where smooth floors are available and anchoring presents a problem with the flooring material. A small vacuum pump is used to displace the air from under the core rig base with rubber vacuum gasket installed.
