What is the purpose of the side handle on a hand ("eggbeater") drill?

In my younger days, I had only this type of drill with which to bore holes. It was often necessary to place the in-line grip on my chest or belt to apply pressure. A board or similar panel provided ...

Why are drill bits often too short for a pilot hole

A "tiny bit of length" difference between the depth of the pilot hole and the length of the screw shouldn't be a problem in most cases. Notes: The harder the wood, the more critical this ...

Cutting a stack of paper into a shape with a router

Is this a workable approach? I don't think so. I think a spinning bit is going to give you a fairly rough edge, and it also won't get into the inside corners that your shape has. Is it safe, or am I ...

What is the purpose of the side handle on a hand ("eggbeater") drill?

"A" reason is that a drill may not spin its bit nicely and freely once in a material. If the bit "catches" (does not spin nicely and freely), thee entire apparatus will then be the focus of the torque....

How to make shallow flat-bottomed hole on 5mm thickness wood slice?

If you have a plunge router, I'd clamp the wood slice from above with a larger chunk of wood. To help a little with maintaining position, I'd tack two tracks onto your worktop. (Make them shorter ...

Drill press, chuck falls down. How do I repair?

Does the chuck have a tapered shaft on its back end? That is called a Morse taper, developed for quick-change operations back in the day. The proper way to re-install it is to slide it into place, ...

What features should I look for when buying my first drill?

Corded drills are good for quick drilling jobs, but they are heavy and require a nearby electrical outlet or extension cord, making them less convenient. My old, cheap corded drill is extremely ...

Drill a perfectly centred hole in a cylinder

If the hole is big enough to fit a bowl gauge in it (for instance, if you're making a cup), you can get a perfectly centered hole by mounting the cylinder to a lathe and turning it like you would turn ...

Drill a perfectly centred hole in a cylinder

How to make shallow flat-bottomed hole on 5mm thickness wood slice?

Either a router or a Forstner (or similar) drill bit are both good ways to make the recesses you want, but in a small piece of wood I think a drill bit is clearly the better option. If you can find a ...

What's a "Brad" and What's a "Lip" When Talking About a Wood Drill Bit?

The "brad" on a brad-point bit is the center point. It bites into the wood easily and helps to keep the bit from wandering when you start your hole. The "lip" is the outer edge of ...

Adapting a 4-jaw drill chuck to hex shanks?

Is it possible to make a combination tool?

Drills operate at a much slower (factor of 10) rotational speed than routers (~28,000 rpm for routers, ~3000 rpm for drill presses; both should be slower for larger bits). It's therefore not possible (...
