Doesn't oiling a hot drill bit change the molecular structure making it brittle and requiring oiling each use thereafter?

In most cases I wouldn't think the bit would get hot enough to change the temper or heat treat of it. When drilling you should always use some kind of cutting oil to aide in the removal of chips and to keep the bit cool.

Why spoons are never made with ionic or polar molecular?
they will be brittle
Is a brittle compound a molecular compound?
Periodic table lists elements. Not properties. Brittle is a property (of metals).
Where Brittle deformation is generally seen in?
Rocks with strong internal molecular bonds
Why can't high temp 1200F soldering irons be used for silver soldering?
Because at that high of a temperature the solder's molecular structure breaks down and changes, and the solder becomes way to brittle causing a bad connection if you can even make one
Why do you heat treat?
You heat treat to improve the molecular structure of the steel. In the untreated state steel is very soft and is relatively easy to bend but when hardened the steel become very hard and brittle. The steel is so brittle after hardening that if say dropped on a concrete floor it may shatter. Tempering relieves some of this stress and makes the steel hard but not too hard.
What happens on a molecular level when tempering steel?
Grain Size of the steel get changed. Steel Become more hard and it become brittle.
What type of solid is peanut brittle?
It is an amorphous solid. The sugar in peanut brittle is melted and then is cooled too fast for the crystalline structure to properly reform, making it irregular.
Is brittle metals or nonmetals?
it depends on the layout of the structure... take graphite for example.. its a form of carbon but is very brittle... but dymonds ar also carbon and have a completely different stucture.. dymonds are not brittle... carbon is non metal.... metals can be brittle aswell... especially is they are heated and cooled quickly
Is sodium brittle?
Sodium itself is neither brittle nor a compound. It is a soft metallic element. Compounds of sodium are often brittle because they consist of a crystal lattice of oppositely charged ions. These ions are arranged in a manner so that opposite charges (which attract) are as close as possible and like charges (which repel) are as far as possible from each other, resulting in a rigid structure. If a force is applied to this structure it can cause part of it to dislodge from the rest.
Is brittle a metal or a non metal?
metals
Why is talc softer than quartz?
Talc has a mineral structure that makes it very brittle all the way down to the molecular level - it only needs a touch to break and so it is considered a 'soft' mineral because it is so weak and breaks so easily.
What changes in the bone structure to cause them to go brittle?
What is referred to as 'brittle bones' is called osteoporosis. The change in the structure of bone that causes them to become brittle is a loss of bone density from a depletion of calcium. Think of Swiss cheese: it has holes in it. That is what osteoporosis looks like inside the bone. Instead of it being dense and filled with calcium, it has lots of holes in it, and so becomes weaker and more likely to break, or fracture.
