If you’re looking to add a splinter free dado set to your tool inventory, then you owe it to yourself to have a look at the 8"x24Tooth CMT Precision Dado Set, model # 230.524.08.

When I think of “must have” accessories for the table saw the first thing that comes to my mind is an accurate miter gauge, the second thing that immediately pops into my mind is a quality dado set. A dado set is invaluable when it comes to cutting dados and rabbets but did you know that a dado set can be used for so much more. Used to cut tongue and groove joints, box joints, half lap joinery, tenons etc., a quality dado set is a table saw accessory that is well worth the investment.

However, with the number of dado sets available today the question has always been, “which dado set is right for me”. If you’re plowing out dados in construction grade material where a splinter free finish is not a concern, then almost any dado set will do but if you’re looking to cut precision dados, rabbets and joinery, you’ll need to step up your game and that’s where the CMT Precision Dado Set comes in.

The CMT 8"x24Tooth Precision Dado Set comes packaged in a rigid carrying/storage case and includes (2) 24 tooth outside cutters, (4) 1/8” four wing chippers, (1) 3/32” four wing chipper (made especially for undersized plywood), (1) 1/16” four wing chipper, and a ten piece colour coded plastic shim set. With the various thickness chippers and the shim set, the user can cut a multitude of dado widths between 1/4” and 29/32”.

Features include the anti-kickback design which greatly reduces the chance of “overfeeding” material while cutting, four tooth chippers that cut smooth flat bottom dados, large CMX-4 micrograin carbide teeth for repetitive sharpenings, laser cut high grade German steel blade body with Rockwell hardness of 42 to 44 and CMT’s specially-formulated silver-copper-silver brazing, attaching the carbide teeth to the steel plates.

When looking at the dado set you immediately notice the generous amount of carbide along with the anti-kickback design and the quality brazing that holds each tooth in place. Some dado set manufacturers sell dado sets specifically designed to cut splinter free in melamine and plywood. They then offer another dado set that cuts splinter free in softwoods and hardwoods. The CMT Precision Dado Set, model # 230.524.08 claims to be able to cut splinter free in all of these materials….does this dado set accomplish what it claims to be able to do….let’s find out.

CMT Precision Dado 230.524.08

In order to cut a dado that’s truly splinter free on the surface of any material, the two outside blades of the dado set have to be able to slice surface wood fibers and CMT accomplishes this by using a combination of flat-top-grind (FTG) and a 20 degree, alternate-top-bevel-grind (ATB) on the outside blades of this dado set.

However, this desired “slicing effect” can come at a price, namely “bat ears”. Bat ears are a result of using a high angled alternate top bevel grind on the outside blades of a dado set. Some dado sets have a very pronounced “bat ear” while others like the CMT Precision Dado Set have bat ears that are within the realm of acceptability. It is a bit of a trade off so to speak, a splinter free dado with a perfectly cut 90 degree shoulder with only a minor bat ear is completely acceptable in my book. I have dado sets without the high angled alternate top bevel grind on the outside blades and they simply do not produce a splinter free surface. If I wanted to completely eliminate the bat ear effect, I would cut dados with a router bit but then I would lose out on all the benefits that a quality dado set offers.

So, with all that said, the question that begs for an answer is, does the CMT Precision Dado Set deliver on its claim of being able to cut splinter free dados in melamine, plywood, softwoods and hardwoods….absolutely! The CMT Precision Dado Set cuts splinter free dados in veneered sheet goods and cuts equally as well in hardwoods and softwoods.

The CMT Precision Dado Set performed flawlessly in all the materials I tested and without the slightest bit of splintering, even when it came to cutting dados in melamine-coated particleboard, a material that is notorious for splintering. And all without using a zero clearance throat insert in my table saw.

With splinter free cuts, this dado set is ideal for cutting more than just dados and rabbets. This dado set works well when cutting various types of joinery and its four winged chippers make easy work of plowing out material, leaving a flat bottomed dado or groove.

An added bonus to this dado set is its ability to run smoothly. I installed the complete dado set, with all the chippers included, into my table saw and cut a number of dados. I was amazed at just how vibration-free this set ran. I tried the same set up with three other dado sets I own and the CMT Precision Dado Set ran the smoothest of the four sets I tried.

CMT Precision Dado 230.524.08

Without a doubt, the 8"x24Tooth CMT Precision Dado Set, model # 230.524.08 lived up to its claim of being able to deliver splinter free cuts in melamine, plywood, hardwood and softwood. From its blade geometry to its ample supply of carbide and so many other features, this dado set is the dado set I now reach for when I need to cut dados, rabbets and so much more.
