I bought this for my son’s cub scout den. We built candy dispensers and this worked great for the adults. I have to say that the length made it difficult for the 10 year olds to keep square but that is to be expected.

I needed a long bit to drill pilot holes for some long lag bolts. This bit worked great. As with other small bits this long, you do have to be careful using it. It is easier to bend/break it then it is for a shorter bit.

Excellent product – very thin and long bits like this tend to break. this did not.

It’s a long drill bit and it drills a deep hole. Just what it is supposed to do.
Carlotta Hansen (verified owner) –
It’s a fine drill bit. However, the height listed in the Specifications came out of thin air. This bit is 12 inches long, not 7.75 inches.
Pete Schimmel (verified owner) –
worked great for what I needed and it didn’t break which a lot of drill bits tend to do

Imelda Williamson (verified owner) –
Very sharp. It does the job I needed it to do well.
Ahmed Denesik (verified owner) –
It served my purpose but was expensive for what it was. Of course, I’m not a pro and I’ll probably be lucky if I ever find another use for it. But I needed the task to get done. So value suffers but as far as Overall rating and Quality, I’d say it’s good.

Drill is exactly as advertised. Shank is straight and drill is accurate.

This drill bit provided the extra length I needed as well as being a quality black oxided bit.
Hester Green (verified owner) –
Performed as expected, would purchase again if necessary.
Clark Kilback (verified owner) –
Perfect tool.
Kirsten Wintheiser (verified owner) –
The drill was perfect for the job at hand. It hit full rather quickly but I’d been warned that the wood I was boring was very hard and tended to dull tools quickly.

Really great for tough to reach spots. A well made product.
