I own several HF tools including plug in power tools. A few years back someone broke into my truck and stole all of my power tools. In these tools I had a $500 Milwaukee Hole Hog drill. I made due since until I was recently hired to to wire an entire new construction house for electrical. There was no way I was going to drill all those holes with my dewalt hand drill, and I did not have the money on hand to buy a new hole hog.... I did some research and found that HV had their own version of the hole hog for I think $129 regular price and on sale on the web site for $89. I when to the store, asked if they price match the site and they told me yes, so I bought it with a 2 year extended warranty for an additional $10. So if it fails for me any time in the next 2 years I get a no questions asked replacement.
Every time I buy a tool there that is even suspect, I get the 2+ year replacement on it.... believe it or not, I have yet to use it.
The hole saw I bought there, I used it for the entire house with a 1 1/4 inch by 18 inch long bit and a 1 1/4 inch by 8 inch.... and once I used a special 1 inch bit that had a thinner shaft made for smaller drills, and the torque this drill put out actually twisted the shaft on this bit.... LOL
