Gotta make sure you have use for the 50 bucks in merchandise you have to buy before your 5 dollar purchase kicks in. However, at the price that the consumables cost for these things, that's a good place to spend the 50. One of the most useful and common blades is over 9 bucks ea and they wear out in minutes. Some of the other brands of blades are slightly better. The last HF semi-circular blade I bought broke the rivets to the hub right away. They're pretty much junk.
We have had a few long threads about these over the years and the general consensus is this is one of the better tools that HF has. I have had mine for 3+ years and used it a bunch and it is still going strong. Still I wouldn't spend $50 just to get this for $5 when they routinely put it on sale for like $14.99.
I've got one. It's made half a dozen cuts with no problem. I would hate to use it all day, though, the vibration is hard on the hands. And yes, I got it on sale or coupon, the only way to buy HF.
I was there today. The cutting tools run up to 15 bucks. If you will buy lots of cutting tools from me I'll give you the Multi-function Power Tool. Hilti has had this philosophy for years. That's all HF is doing.
Took the "plunge" and bought my first corded tool from HF !!!!
Spent the $50 required of coupon. . . I actually spent $64 after 25% off coupon for framing pneumatic nailer . . and got the corded oscillating tool for $5. For less than $70 was out-the-door with both tools and another free tarp. Oscillating tool will get used on friends bathroom tile floor that is trashed and needs removed/redone.
Ran into guy in parking lot who had positive things to say for oscillating tool. He even bought extra 25% coupon & $5 tool coupon that I gave him (he wanted a 2nd oscillating tool for $5) !!! Think I got around $2 which was his loose change in pocket.
The problem with the harbor freight plasticky tools is that they're LOUD! They're not complete **** though. I recommend you pick up a pair of decibel reducing ear muffs while you're there if you buy this kind of stuff (or just ear plugs). Their ear muffs aren't bad actually; no frills though.
