Very handy, but soft metal used – 0~14mm Steel Hole Saw Installation Kit Reviews

Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

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:
I'll definitely buy another one and try to do heat hardening of the tool before use to make the tool stronger.
Bottomline:
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.
