If it's a corded drill, that's a common sign that the cord is going bad and it's time to replace it. It might also be the power switch (see below). If it's a battery drill then look to the power switch. Dirty contacts will cause intermittent power loss. You may just have to spray some contact cleaner into the switch assembly and work it a few dozen times, ...

Pre-drilling is not just about wood-splitting. It fundamentally changes the nature of the joint. Take the example of screwing decking to joists. If you were to pre-drill the deck board so the hole was WIDER than the screw but the screw is allowed to bite into the joist. The joint becomes much like a nut-and-bolt where the entire joint is held in place by ...

The reason the hole is drilled is to remove excess material so that when the screw bites in, it does not rip the wood (or whatever) apart. It's simple physics. When the screw does in, if there is no hole, then the wood volume occupied by the shank of the screw is displaced. Where do you think that wood goes? Outer space? Forcing screws into wood using an ...

If the wood is prone to splitting, it'll still split when you don't drill pilot holes, impact drill or not.

You can use your rotary hammer if you don't mind the fact that the hole will not achieve perfection on quality. But you can use bigger drills and not overexploit your tool. If you need perfect holes (like you need at wood, for example) then you must use hammer drill. But with smaller drills!

You could use a flexible shaft bit holder It easily bends to 90 degrees, is designed to be used with hex shaft bits and takes up less room than a 3/4 inch bit. Images and links are for illustration only, not an endorsement of products/sources.

You could try a 90 degree drill bit adapter.

Here's a/the bosch version - no idea if it fits your particular version of bosch 18V battery, which come in many incompatible versions, but it's the only one I can find. Just making an "answer" to get the picture in...

My problem drill was not cordless. Away from home I had few of my usual tools to get the bit unlocked so I used the wire on the drill. I wrapped one end around the base of the chuck and the plug end around the other so that there were a couple of turns around each. The wire was round and soft and needed to be wound in the correct direction so that it ...

Most low voltage drills are targeted toward hobbiests than anyone else, and a 7.2V drill is likely not going to be much use for driving screws. It will likely do fine for drilling holes, but there is generally a pretty strong relationship between voltage and torque. If this is something you'll be doing enough to justify the purchase, I'd look for ...

Personally, I never use battery powered drills and would advise against them. The drill bit should be the size of the screw minus the threads. In other words, if you filed off the threads of the screw, the rod left behind is the diameter the drill bit should be. Machinists call this the "root diameter". In many cases you need to actually drill three pilot ...
