Cordless power drill |
Hint: pretty big... Tracy blows it from the get-go, by telling her readers that,
"The portable electric drill consists of a housing with a handle, a motor, and a chuck. Most of these electric drills have a key-type chuck."Well, no, corded drills often have a keyed chuck, but most cordless models have a keyless chuck. But there's more:
"The most common shapes are the pistol-grip drill which usually will hold drill bits up to 1/4"..."We think Tracy meant 3/8 inch... but then she goes on. Among the "safety tips" she cribbed from somewhere, we found the exhortation,
"Never use a bit with a square tang or a lead screw."We aren't even sure what that's supposed to mean! We do know what
"Make certain the drill is clamped securely in the chuck."
"The cutting tools can be twist drills, auger bits (if they have straight shanks), or spade (speed) bits."A) Is there such as thing as an auger bit whose shaft isn't straight? and B) a spade bit is not the same thing as a speed bit. And finally, Tracy attempts to pass along her vast knowledge by telling her readers how to drill a hole, including such useful information as
- "When drilling holes with your portable electric drill always use the correct bit or accessory." (Duh...)
- "Make sure the tool (preferably of high-speed steel) is sharp." We like carbide tips for some jobs, Tracy.
- "Always clamp the wood in a vise, or hold it securely with a clamp." Yeah, right... "Always"...
