I know this is about bits but there is always the push to upgrade the drill.

There is the age-old argument about which is better to upgrade; many people believe drills come and go but legacy bits are forever. There is always some excitement to chucking up a new bit, especially if going from flint to say, stainless, and seeing if the hole is up to snuff, however. If it puts a smile on your face, you made the right choice.

Isn't there a good drill cheap bit vs a cheap drill good bit on you tube? Drillgital Rev must have done one.

Did you know that titanium shavings are highly flammable?

There are plenty of metals that are pyrophoric when reduced to small shavings, what IS important is that the appropriate fire extinguisher to deal with it is nearby. This reminds me of an incident back in a laboratory I worked in years ago, where a undergrad didn't realize the acetone he was using in an experiment wasn't completely anhydrous; there was water in it. So when he put in the sodium metal which promptly exploded and set the acetone ablaze, and splashing it all over the rest of the apparatus - the best thing he could think of was to use the Co2 fire extinguisher. The sudden blast of cold compressed Co2 caused a temperature differential which the glass apparatus couldn't handle, so it simply shattered: spreading sodium chunks, flying glass, and acetone that was heated well beyond his flashpoint all over the place, sparking new conflagrations that were punctuated by the popping of sodium metal still reacting with water.

The IQ of a drill is better when the mill,
Has a sturdy morse quill.

But to get the real answer,
Send the the hole to a quorum.
They say the best IQ number is from Mensa,
And not the flaming forum.

We had a similar incident in my HS lab years ago. Im our case the exploding substance was in a petri dish, which the fire extinguisher through across the room to break to bits on the back wall of the classroom.

The poor gy who's experiment blew up used the exact same procedure everyone else did, we were all watching. We never came to a conclusion about why he had a problem when the others in front of him didn't.

+1 I love reading about idiotic lab accidents, for some reason I always see them as Dr.Bunsen and Beaker skits. Unintentional disasters are funnier when puppets are involved, running around flailing their puppet arms

But if the new owners make changes, I am worried the new ones will look like this:

They should do the decent thing and put the "Stanley" name in some discrete location on the serial number plate and leave the main name and color as they have been.

Neither is really known for sharp results.

...am having disturbing flashbacks to organic lab with visions of flaming waste troughs. I kid you not...very, very scary.

As for flaming chunks of sodium metal...that happened in high school. A few textbooks bit the dust.

Could have been avoided with a simple firmware fix. Just sayin'...

Gotta be careful with firmware updates, Steve ... I want to drill my brick, not brick my drill!

actually saw that

a promising career went out the collection port

who knew one hand held that much blood?

we did learn about taking too big a bite when squaring stock

That is very sad. The hazards of the joiner were so great that my high school shop teacher would not allow us to use it.

We have buckets of talc in case of a titanium fire.

Sounds like a 3 Stooges episode.


The electric utility I worked at for 30 years had some sodium filled wire in the electric distribution grid way back when. It wasn't long before they decided to replace it all, for what became obvious reasons.

Seems like every time there was a wind storm, and trees took the lines down they would inevitably fall on wet ground, or into a puddle (even better). Even when a breaker opened and the conductor was no longer energized it still put on quite a show. The end of the wire would explode and fling itself into the air, then fall tot he ground again and the whole thing would start over.

Proved to be quite tricky gathering up the downed lines so new ones could be strung and power restored.
