Browse all brands ». Browse all categories ». One of the most widely used power tools for carpenters is the table saw. We are not including cordless table saws in this test as we plan on doing another head-to-head exclusively for cordless table saws later this year as several are available now.

Once again our team has put some serious time and effort into our Head-to-Head evaluation to bring you the most comprehensive information available. All 8 of these freigyt table saws are similar in size and capacity.

Each of the saws 10 table saw blade harbor freight zero a 10 inch blade, 15 amp motor and they are all able to use a dado set.

Specific differences in the saws are listed below. One of the things we looked at was the ease of assembly out of the box. We had the same person assemble each of the saws and timed the assembly to see if blace are any significant differences between the models. The assembly time for the saws ranged from 21 minutes to 48 minutes.

We also did some testing of dust collection to see if there were any significant differences between the saws. We attached a Bosch dust extractor to each saw and measured the weight of dust collected for a fixed number of cuts. The bottom line is with a good dust extractor attached there was negligible difference between the saws.

Lastly, we spent some time evaluating the fences. Rack and pinion fences are quicker to adjust, hold in place better during cuts, and provide better accuracy.

In the commercial construction business, we typically buy a job site saw for each project and use it up during the course of an month job. When these saws hit the site, they are unboxed, assembled and immediately put into use. We rip stacks and stacks of sheet goods with these saws and the tolerances of the cut materials are not very critical.

What if a contractor uses their job site saw for high quality built-ins or high tolerance finished cuts? In that case, saw accuracy is critical for that work. In this use case, if the saw is immediately put into use, success depends upon the out-of-the-box accuracy from the manufacturer. The quality of the cuts and more importantly the potential safety of the operator is going to be a function of the as-shipped accuracy of the saw from the manufacturer.

TBB compared the relative accuracy of the test saws as soon as we assembled and set them up. We measured the manufactured tolerances and found out.

We analyzed the data from the tests and ranked these saws for as-built accuracy. To assess the manufactured accuracy of the eight saws, TBB looked at six areas to measure and compare: Table Flatness, Accuracy of 45 Deg. Stop, Accuracy of 90 Deg. We evaluated the flatness of the table by measuring the flatness by placing fable edge of a precision ground flat bar across the table and placed feeler gauges in any gaps to measure any difference between the bladde bar and the table.

TBB took measurements in four directions. As the operator faces the saw, we measured the flatness at the arbor from front-to-rear; we measured the left-to right flatness at the arbor; we measured the flatness from the upper left-to-lower right table corners; and, finally, we measured the upper right-to-lower left flatness 10 Table Saw Blade Harbor Freight Meter between the corners.

We compiled this set of data and created a ranked set of results by assigning a rating to the relative values bladde the test measurements. Then we ranked the saws for overall as-manufactured table flatness. As a point of interest, a typical sheet of copy paper is approximately. Flatness measurements varied from 0.

All of the data for the table saw flatness can be found here. The overall ranking of the table saw flatness is in the following table:. TBB measured the accuracy of the factory-set 45 degree stop by using a Wixey WR digital inclinometer. This device has hqrbor accuracy of 0. We placed the Wixey gauge on the table and calibrated the inclinometer to the table by zeroing 10 table saw blade harbor freight zero the gauge.

After that calibration, the measurements shown on the gauge give a result that is relative to the saw table. We attached the gauge to the blade and used the saw mechanism to adjust the blade incline to the point at which the blade or trunnion hit the factory-set 45 degree stop and recorded the measurement.

TBB ran the test twice to ensure the repeatability of the measurement. In every case, the result came out to within 0. Ridgid was almost a full degree off from the 45 stop. TBB measured the accuracy of the factory-set 90 degree stop by using a Wixey WR digital inclinometer. After that calibration, the measurements give a result that is relative to the saw table. We moved the blade to an 10 table saw blade harbor freight zero position of 70 degrees off vertical.

TBB attached the gauge to the blade and 10 table saw blade harbor freight zero the saw mechanism to adjust the blade incline to the point at which the blade or trunnion hit the factory-set 90 degree vertical stop and recorded the measurement. The results are shown below for the accuracy of the 90 degree stop. The Hitachi, Delta and SkilSaw could use some calibration.

TBB used an iGauging digital dial indicator to measure the accuracy of the blade position to the table miter slot. This instrument has an accuracy of.

As 10 table saw blade harbor freight zero of the table saw set-up, TBB installed a new Diablo blade in each saw and these never-before-used blades were used in the measurement test.

To ensure that any wobble in the blade did not enter into the test results, TBB marked a 10 table saw blade harbor freight zero tooth as the reference point for the measurement. The blade position was moved to the front of the saw to allow the iGauging dial indicator to hit the tooth immediately behind the carbide tooth, The iGauging dial indicator was calibrated and the indicator had a reading zer zero.

We rotated the blade to the rear of the saw to enable the 10 Table Saw Blade Harbor Freight Ii dial indicator to contact the same location of the same tooth behind the carbide portion. We positioned the dial indicator to the rear of the saw placed onto the blade and the reading recorded. If the blade and the miter slot were closer together at the rear of the saw, the dial indicator has a negative reading.

If the blade and the miter slot were father apart at the rear of the saw, the dial indicator showed a positive reading. The results for the blade parallel to the miter slot are shown below. Again the SawStop had a perfect reading right out of the box and the Ridgid needs some extra calibration in order to get the blade more parallel to the miter slot.

The accuracy and safety of any given saw is dependent upon the blade being parallel to the rip fence. Since we tested the amount of difference in parallelism between the saw blade and the miter slot in the previous test, we need only to see if the miter slot is parallel to the rip fence to see if the saw has a parallel relationship between the blade and the rip fence.

TBB used the same iGauging digital dial indicator to measure the accuracy of the as-delivered 10 table saw blade harbor freight zero fence sero the table miter slot. Next, we positioned the dial indicator to the rear of the saw placed onto the rip fence and took the reading. If the fence and the miter slot were closer together at the rear of the saw, the dial indicator has a negative reading.

A negative reading meant that the materials being cut might be subject to being pinched and a kick back more likely to occur. Remembering that a sheet of paper is approximately 0. One term you may hear when reading about table saw accuracy talbe blade runout.

Runout is a term that describes whether or how much the outside edge of a saw blade wobbles while being held by the motor shaft. Sometimes, operators measure runout by using a saw blade. In that case, the very use of a saw blade presumes that bkade specific blade is perfect or nearly perfect 10 table saw blade harbor freight zero its flatness.

Using a saw blade that has any warping will not give a clear indication of blade runout. To ensure that our runout measurements were accurate, TBB used a Freud calibration plate. While TBB does not have a means to measure the accuracy of this specification, we did put this calibration plate on top of a polished granite calibration table and could not shine a light under any portion of the plate or slip freighf 0. We used the Freud calibration plate on each of the test saws to measure runout.

We removed the new Diablo blade, installed the calibration plate, and raised the trunnion to its maximum vertical adjustment. Before measuring the runout, we placed a black mark hlade the calibration plate to give a consistent starting position for the runout test.

The same iGauging dial indicator provided habror test measurements, only this time, the units were set to read out in mm. TBB noticed that in the initial saws, the movements were sufficiently small to need the smaller metric units.

TBB placed the dial indicator on the starting position of the calibration disk and calibrated freiight position on the dial indicator to a reading of zero. We were very careful to rotate the creight plate by using the outside rim so as not to impart any side-to-side force on the plate that might introduce errors into the measurements.

While we rotated the plate, we freighy the maximum reading on the dial indicator. We validated each maximum reading by running the test for a second time and noting that the readings were consistent.

TBB also noted that as 10 Table Saw Blade Harbor Freight Online we performed these tests on all eight saws, the maximum readings occurred at different parts of the plate along its rotation.

Because the max readings were in different and discrete parts of the calibration plate, TBB hable a very high level of confidence in the flatness of the calibration plate, itself. As you can see above the runout ranges from 0. Typically values below 0. Both the Bosch and SkilSaw are in a range that needs further evaluation especially if the saw is to be used for finish work. From the 10 table saw blade harbor freight zero of the six individual tests above, we compiled a summary ranking for the overall winner of the as-built accuracy.

The ranking for the summary follows:. As we said in the bladee of this section, many of these saws will be used, right out of the box, 10 table saw blade harbor freight zero rough cutting materials and the fine accuracy may not matter so much in that application. If this is the case for a saw, the quality of the cuts and more importantly, the potential safety of the operator is going to be a function of the as-shipped accuracy of the saw from the manufacturer.

So, TBB wanted to see how the various saws compared right out of the box. The results are in and, as a group, 10 table saw blade harbor freight zero eight saws measured up quite well for out-of-the-box accuracy.

It should be noted that all of haarbor saws were 10 table saw blade harbor freight zero after the accuracy evaluation prior to the performance testing.

With the exception of blade runout the other adjustments can be made to dial in the saws. The first measurements we looked at with the performance testing was blade speed cutting all three of the test materials.
