0~14mm Steel Hole Saw Installation Kit

Pros: Hard to believe but there it is, in DX! Very well taken machined. The corners are very well finished. The alumininiun is excellent quality. It has a finish in black, mimicking Armory´s Old Times.

Cons: For an idiotic project, the cable is not screwed at the tip, which would make the tool longer and much more easily to handle it, safely kindda.

Other: Gift your friends, they'll be crazy!

Pros: Make a clean hole out of my polycarbonate RC car body. Come equiped with a cap so it is a lot safer. Looks to be a quality product. Metal all around Really sharp.

Cons: nothing really. I found a cheaper similar produck somewhere else (4 bucks) also from hongkong but i dont know about the quality.

Other: Good First impression, i hope it stays true the more i use it. At 7 dollar get it if you play rc car and buying a lot of new RC card body as this will make a clean hole and make work a lot easier.

Pros: - Essential tool when you need to make hole in any soft material like polymers or soft wood. - Especially good for rubber e.g. for extending hole in rubber gasket. - Makes clean edges when used properly. - Easy to use.

Cons: Very soft metal of cutting part makes it unusable for anything harder than pine wood. I damaged cutting edges slightly when cutting in thin aluminum can. Then I totally destroyed tip of the tool when tried to bore woodchip board: it was bent and it's absolutely impossible to straighten it back properly.

Other: You really need this tool if you often drill/extend holes in rubber or plastics: it is really handy for installations and adjustments. Don’t even try to use it for wood or metal or you’ll destroy the tool.

Pros: * Good for working on plastic enclosures for circuit prototypes. Holes can be easily cleaned up or expanded.
* Pieces fit nicely and it feels solidly built.
* Edges are sharp enough to create smooth holes.

Cons: * Handle could be longer for a more stable grip. Maybe the cover could attach to the back of the handle?

Other: * If you need to make clean, custom-sized holes in soft materials such as PVC or ABS plastic, then this is a good tool. I have not tested with wood or any metals.

Pros: - Handle has knurl. - This tool able to make the ideal holes in the soft materials quickly (plastic, circuit boards, soft wood, etc.)

Cons: - Handle should be longer for more comfortable work during long time.

Other: Good tool for this price. It can be excellent in case a handle will be longer.

Pros: Light, cheap and does what it's made for: widening holes in softer materials. Handle and cap are made from aluminum, the blade-part is steel i guess (magnetic). Blade can be removed by loosening a small hex-scew. Blades and tip are extremely sharp / pointy and should be handled as such. I already used it for several "hacks" and let me tell you: It's awesome! This tool is widening pre-existing holes in PVC and polycarbonate like a boss - clean chipping as it should be, perfect holes without losing center or irregular sides. It will NOT be useful for making the initial holes itself. Even punching thick cardboard will mess with the tip, be very careful! Always dremel the hole you want to like 1-3mm and then widen it in small steps to reach your final width.

Cons: The only problem is that you get conical holes - since the blade is conical. But usually that is not an issue. The blade is pretty soft - if you wanna use it with aluminum, make sure to work slow and provide good centering. Very hard types of aluminum wont work out and just dull the blade. You have been warned!

Other: I nominate this for the prison-shank-of-the-year-awards with a 99% chance of winning 1st place :-)

Pros: Light-weight tool; great (if soft) cutting edge in a well-machined package with very nice comfortable knurling and finish. Cutting edge is very sharp... and perhaps even a bit too acute a slope (i.e. very small angle). This might actually be a CON for some people... I'll leave that for others to judge.

Cons: I'm docking it two stars on ease of use for the rather idiotic design flaw of not being able to screw the handle to the other side of the tool - which would allow for a longer grip and safer tool. The short barrel length and EXTREMELY sharp point are not a good combination. Also, there is absolutely no need for the point to be needle-sharp and first thing I did was to cut it off with a Dremel cut-off wheel about 2mm. The reason you don't need it so sharp is that this is not for drilling a hole but for "smoothing" or "enlarging" a drilled hole. If you want to use it for extremely small holes, maybe just blunt the tip a bit or at some point you will stab yourself.

Other: Great tool for the price. I'm sure the edge won't last for years but for 7 bucks you'll get plenty of use out of it.
