If you are uncomfortable using it in a hand drill that's fine, for you.
Step drills are used everyday in hand drills - I use them every day in a hand drill.

The safest thing to do is to do nothing...

Believe me, using a step drill in a hand held drill is safe.

Canadian Tire sells mostly junk now, not much better than a dollar store but they have varying quality.
As for the dollar stores, I don't go to them and I certainly wouldn't buy any kind of tool in there...

Would you be surprised to know I found the same manufacturer stamp on a "Power Fist", "Mastercraft" and a "Craftsman" planer and drill press cast housing?

They all come out of the same Chinese facory

So why not go for the best bang for the buck?
(Yeah, I know they aren't good brands, but for prototyping and occasional custom builds, it's all I need)


I have three qualities of bits on hand I've found optimum for my prototyping work:

- A set of top notch HSS for wood/plastic.
- A set of where-I-can-get-'em-cheap Titaniums for aluminum chassis.
- A set of cobalts for steel/thick aluminum.


As for the hand/press issue, it's all up to one thing - experience.


Cheers!

Steel Hammond/Bud/etc. chassis... titanium coated are OK, but do use the cheap ones, cause the expensive ones will wear out just as fast as the cheap ones and you don't feel as guilty when you dump them in the bin

Cheers!

I would like to revise my list and add laser cutting to the top.

Another way to put holes in the appendages

There's a fellow on the Dutchforce electronic forums using one of them things to blast holes in various substances around his shop. I suppose when the novelty wears off, it'll get used on real chassis
