Inspired by that Skil HD5510 review, I’m going to ask you all this: how does the 1993-current HD5510 5-1/2” trim saw hold up over such older generations of it, like the original 1983 model 551 and the 1986 model 5510?

1992 was the first year that Skil and the U.S. division of Robert Bosch merged; four years later, RB would buy out Emerson Electric’s 50% (or whatever) share of the joint-venture (Emerson Electric bought the then 55-year-old Skil in January 1979). I’d like to think this was when the quality of most power tools began to decline.

How many of you actually have a circa 1983 model 551 or a circa 1986 model 5510 to show us here?

Thank you,

Ben

It’s been awhile since your post, but I was trying to find out information about my Skil Model 551 and came across this.

FWIW, my Skil 551 came with a manual with a publication date on the back of 11/81, which suggests to me that the original Skil 551 cam our earlier than 1983. Don’t know how to tell otherwise, but thought I’d mention it.

Also, by looking at the specs for the current model ((5510), I discovered a couple of differences: My 551 has a 5/8” arbor, the 5510 has a 1/2” arbor; and the label on my 551 says its RPM is 4000, while the 5510 is spec’d at 4500RPM. Both show that the motor is 6.5A.

I downloaded the 5510 manual to compare it to mine. Much of the content of the two manuals seems the same. The 5510 manual includes more information overall, including a comment that the bearings should be replaced every 300-400 hours (or every 2nd brush change) – that’s not mentioned at all in my 551’s manual. Otherwise, there doesn’t seem to be a lot of difference.

The “Features” of the 5510 stated on the website include statements that it has “Precision cut helical gears for longer tool life” and “Ball Bearing Motor Construction for increased durability, twice the life”. Nothing I have tells me whether either of those statements is also true for my 551.

The cord on my 551 has a 3-pronged plug. I can’t tell from the online or manual pictures whether the 5510 has a 2 or a 3-pronged plug on it.

I also downloaded the parts list (& diagram) for the 5510 – from what I can tell, it looks pretty much the same as my 551. The parts list diagram doesn’t show the plug on the cord, BUT the cord has 3 wires coming into the unit, so I’m guessing there’s still a 3-pronged plug on the 5510 like on my 551.

That’s about all I can tell you. I’d be curious to learn about any internal differences between the 551 & 5510 that anyone knows.

If you could upload pictures of your 551 (it would be a 1982 model), I would appreciate it.

Thank you,

Ben
