General Tools 131 Screwdriver Handle Reamer, 3/32 – 3/8 Inch

Countersink reamers are always a plus in a tool box! Working in a machine shop always have plenty of tools, and I am no professional so these are budget friendly for us average Joe's! Great for sheetmetal, or pipes! I definitely recommend! Nice handle and very sharp edges! These will last awhile! Definitely go with the General!

Works great for mostly wood, plastic, and soft metals. Nice handle. Took 1 star off for poor finish on the cutting edges.

I purchased these for something other than reaming... Honestly, I thought I was getting a smooth awl but these will work perfectly for my purposes. The materials seem to be heavy duty and I don't expect to have any issues with them breaking or falling apart.

I bought this wanting a convenient handle on a reamer and a tip that was smaller than the other three reamers I have...was a little dismayed reading reviews after I placed the order where people said the tip was not 3/32" as advertised but actually 1/8" or a tad larger. The one I received is in fact 3/32" and if you are careful you could probably even use it on a hold just a little smaller (not 1/16" though). On the flip side, the one I received was over-ground just enough so that it will not do a 3/8" max diameter...I suppose this has to do with poor factory methods and QC since these are no longer made here in the US. The steel in these is ok, not great, and the grind is not what it should be, but it works for most applications. Sharpening reamers like this is a pain but can be done. Back when General had better products their reamers were decidedly nicer...these now are on par with most of the China and India cutting products...which means they're serviceable. If you want a nicer reamer but don't want to spend a mint, look at the ones from Engineer (Japan, although I think their reamers are from Taiwan...nearly everything Engineer makes is very high quality) and try to catch those on sale.Anyway, really convenient at times to have the screwdriver handle for quick small jobs and this is much better than any of the hobby/RC conical reamers, and the price makes it a good value.

Works good so far !

I used this to increase holes in both wood and copper washers. It worked perfectly and I would highly recommend. Great and useful to have around.

I needed to enlarge the hole in a copper lug less than 1/16" but this tool won't even cut soft copper! I got a few flakes of copper for the first 30 seconds but after that nothing. I wiped all of the shavings from the tool and tried several more times but this tool wouldn't cut any further and produced no more shavings. It doesn't appear to be dull, it just looks like there is no clearance on the back edge of the cutters so it just scrapes the inside of the hole instead of cutting. This took is useless! I would rate it at zero if I could.

I understand other customers were upset that it doesn't drill out to 1/2 inch, but 3/8ths is standard for most knobs on a guitar. I would highly recommend this tool if you're installing new pickups, pots, or even custom building a guitar. I used this to install new pots on an ESP guitar and worked perfectly for the job. Because it goes up to 3/8s, you don't really have to worry about making the hole to big, and I could safely dig out the wood without chipping the paint. I'd still be cautious about the paint though, just to be safe.

Unit is good but advertised as a 1/8 to 1/2 inch reamer, which is what I needed, but is actually a 1/8 to 3/8 inch reamer.

Make hole bigger
