I know everyone says it's worth waiting for a good deal on a Greenlee set, but what about this? Brand New Knockout Punch Kit | eBay
I'm curious if anyone here has purchased these and what they think. This guy appears to be selling quite a few of them and people appear to be quite happy with their purchases, so I was wondering if anyone from here is a customer...
I'm keeping my eye on Greenlee sets as well and I'll go after a good deal on one of them if it comes up soon.

Look a bit like 'Qmax', the best cutters in the World. Can't speak for quality though bearing in mind one 3/4" Qmax cutter will cost you at least what they are charging for their whole kit!
If you need it more than a one time cut into 26gauge or thinner, go for Qmax. Farnel, RS, Mouser and most good tool suppliers stock them or equivalent types.

This seems to be a very good price, thanks for the lead. My old Greenlees are starting to get dull. I like the 4-point lug-splitter design. If you lubricate the cutting surfaces and threads often they will last a long time. Be aware that the sizes are for conduit knock-outs and actual diameters are larger.
1/2" is about .88"
3/4" is 1.095"
1" is 1.345"
1.25" is 1.69"
Cheers, E

How are the sizes in relation to the various tube socket sizes? In particular, I'm thinking 7 pin, octal, and noval sizes. Will those sizes work for these 3?
I take it that it's okay if the socket holes are a bit bigger than the sockets themselves, as long as there's room for the mounting screws?

I always thought them to be a Mickey Mouse (no relations!) tool, but I got one to install a back-up camera in my car. I was impressed! SKU127567 at Online Shopping for Cool Gadgets, RC helicopter & Quadcopter, Mobile phone, Fashion at Banggood.com. It should do well for tube-sockets in alu or mild steel. E
Yeah. I get the impression those aren't terribly durable. I could be wrong. Not that I'm going to be building a lot of amps in the near future, but I like to keep my options open...
Looks to be the same one Harbor Freight is selling. The photo is identical. So is the price.

That's real service there, Enzo. You mind running by and picking me up a set? ;-)
Just kidding. That's only 3 miles from where I work. Very convenient.
The reviews are less than stellar, though. A lot of people complaining about the screws stripping (sounds like a mismatched screw/bolt size or something).
Thanks for pointing out that it's the same as the Harbor Freight ones!
Maybe I ought to just hold out for the Greenlee.

Wow that's cheap.
I already have a number of Greenlee punches and they have worked well for me.
Ideal for punching out holes in valve amplifier chassis's

I kept looking at the 7235 kits, but what I really ought to do is just buy a 7/8" and 1 1/8" Greenlee chassis punches individually instead of the conduit punches... They're not all that expensive and I think those would handle the sizes I need.
I have some Greenlee punches I have had over 50 years...still work.
I am not into cheap crummy tools, and when harbor Freight exploded all over the country with stores, I was leery. On the other hand I have bought some tools there that have worked out just fine for me. Step drills, for example. I could spend $20 for a step drill somewhere, but will it outlast $20 worth of $3 step drills? Just my own opinion, but I'd have to consider $25 for the convenience of some clean holes now, rather than hacking out some holes while I wait for a deal on a used Greenlee to come along.
Harbor Freight always has newspaper and magazine coupons going, and there is always a free thing. The free set of screwdrivers has worked real well for me, and their crummy little DMMs are like $10 list, and either $4, $2, or FREE very often through coupons. I have a number of the cheap meters spread around the shop and warehouse. They are more than accurate enough for checking continuity through speakers, or to see if a power adaptor is putting out anything. Do I prefer it to my FLuke? Of course not, but to see if a 9v battery is flat or not, the free meter works fine and I don't have to hike the length of the warehouse to get my shop meter.

That tells me that I'm best off buying Greenlees (maybe used) because I'll surely be able to re-sell them later, if I choose, and get a reasonable value in the resell.
I'm curious, do they have markings on them to identify them as Greenlee? It just made me curious if there might be people buying the cheapies at Freight Harbor and reselling them on Ebay as Greenlees.
I've never been to Freight Harbor, but we get the ads. All their stuff looked pretty cheap, so I've never been too interested. It might be worth getting some $3 step drills, though. They wouldn't have to last too long to pay for themselves. Some cheap DMMs would be nice too, though really, how many DMMs does one need? I mean, if you do electronics for a living, I can see needing a few, but I doubt I'd ever need more than 1 or 2.
It was just a small thing, but when your bench is 100 feet from wher you might be checking out a PA setup, having a meter or two sitting around saves time and steps. That is worth FREE to me.
Maybe it is my outlook. I got my chops in field service, I was used to having all my tools at hand al the time. here in a shop situation, I don't pack up my tool kit and tote it around the building. But I still like to have things handy, so I have duplicated various things I use around the place.

That makes sense.
My work space is quite small, so not enough room for many toys. In fact I'll need to put my o-scope aside when I start building the amp and use the space where it sits to build the amp.

Once in a blue moon, I need my scope away from the bench. I usually set it facing straight up on the floor next to me. I an probe the circuit and look down beside my knee. NO bench space. I would rather it above my work on the bench, but sometimes we improvise. Also, consider a riser over your bench for your scope and other gear. Frees up the bench top.
I am amused by your waxing about durability of these punch sets!
Are you using them for hobby or professional work? Professional use tools require putting up the money and caring for your tools. But caring for your tools, regardless of price, is paramount.
I have many metal-working files 55+ years old that still serve me well because I know how to use and care for them.
I have many cheap tools I rarely use and replace when they wear out.
Harbor Freight sells to the hobby/semi-professional market and I use them often. Good stuff for a good price.
I would not buy a used Greenlee punch set. Most likely the cutting edges will be dull (like the one I have, 40+ years old) and I do not know if Greenlee offers a sharpening service. E

From the Freight Harbor customer reviews. You be the judge of whether quality matters:
Comments about Knockout Punch Kit 10 Pc:
The female thread stripped out the first time I tried to use it on aluminum.
Comments about Knockout Punch Kit 10 Pc:
Threads are either too soft (not heat tempered) or bad male female match. Unit will not punch any material. Threads strip out immediately.
Comments about Knockout Punch Kit 10 Pc:
stripped out first time i used it on an aluminum box! dies seem ok but the threads on center bolts are weak
Comments about Knockout Punch Kit 10 Pc:
Bought it to install a new 1/2" electric line from an outside light to breaker box. Had great difficulty getting through the thin sheet metal on the light. Center shaft bent and broke trying to get through the breaker box. Standard metal box should have had no trouble.
Comments about Knockout Punch Kit 10 Pc:
I bought the knock-out punch to install a dishwasher air gap on my stainless sink based on comments by Cliff and Ken G who had success. Stainless sinks come in a variety of thicknesses. Obviously, my sink was of thicker gauge than theirs. The points on the die intended to be the initial penetrators were too soft to handle the task. After reaching a reasonable torque, I removed and examined the tool. The points were flared out such that the cutting die could no longer slip into the receiving die. The product should be clearly labled "not suitable for heavy gauge stainless steel sinks."
Comments about Knockout Punch Kit 10 Pc:
Smaller center bolt bent the first time used, causing cut out to go through crooked and punching half a circle. Returning for refund...

Threads Strip
Comments about Knockout Punch Kit 10 Pc:
I Have had this hole punch set for 8 years and have used it three separate times. On the eighth hole this set has ever punched the threads stripped. I think I am a little out of the warranty period so in the garbage it goes.
Comments about Knockout Punch Kit 10 Pc:
I just could not believe the reviews that this could be that bad. Did not get one 1/2 NPT hole in 10 ga material when the bolt elongated and broke.
Comments about Knockout Punch Kit 10 Pc:
The bolt is too soft and the trerds strip on first time I used it! And Harbor Fright does not seem too care much about replacing it!
