HHIP 1001-0201 Indexable Tool Set, 2 Boring Head, R8 Shank, 4 Boring Bars

Nice storage case. Performed very well and accurate for my first time ever using one. Moving the dial .05 means you will be taking a .1 cut. IE .05 of each side of your circle. Although one of my boring bars is slightly oversize and does not fit in the boring head.. I’m more concerned with its overall accuracy and it’s very accurate.

Solid quality, well made and finished. Everything works almost flawlessly. I'd buy again.

Very impressed at the quality of this cutter for the price! It feels very precision, however I did have to tinker with the 3 gib screws in order to get the head to move smoothly without any "slop" but that's typical with any boring head that uses a taper/gib setup. Run-out is irrelevant, since the tool is supposed to run off-set by design, but even still.. the static upper-section is very straight, and I only measured about .0005 to .001 run-out in 5 separate, complete setup/tear downs, so at least it's consistent! For a home shop, and anyone running a sub 3HP mill, this is more than adequate, and can easily produce bores that match the highest level of accuracy you can produce with any other tool using your equipment. So if you can achieve +-.0015 on your mill, then you should be able to hit that with this head, if the best your mill will do it +-.002 then that's what I would expect with this boring head and well. Definitely worth the money! Glad I didn't buy the cheaper versions through.

The thing works good, the only reason im giving it 3 stars is because its Chinese and you can tell.

Ill start with the disappointment. The R8 draw bar threads were poorly tapped, my draw bar would only start a few threads. This was disappointing on a $200+ head it may have been expected on a $47 Harbor freight unit. Originally I was going to deduct a couple stars until I used the boring head.I was very happy with the rest of the package. The boring bars were high quality and with the replicable carbides makes a nice package. After mounting it in my mill and boring a few holes in some half inch scrap I was quite happy with it, thus the 5 star rating. I didn't feel it was fare to be negative when the tool did perform very well as intended!!This appears to be the same set as sold by Shars???

What a surprise was in a nice case with all the allen wrenches. nicely oiled much more precision than I expected. If I had any words of wisdom, where the boring head screws on to the R8 chuck needs unscrewed and a little blue of green Loctite applied. Great addition to my Bridgeport tools .

This boring tool works as advertised

No complaints about the boring head itself or the bard included. I've used it boring up to 4.5" holes in 2" 316L SS flanges that were too big to bore in my lathe. The inserts that come with it, however, are basically crap (that's what I expected); you'll need to find some reputable brand inserts from your favorite supplier. I currently am partial to SECO inserts.
