It depends on what small is. A baby elephant is around 250 pounds heavy when it is born and stands at around 2.5 feet tall. Elephants grow very fast and by the time they are 5 years old they weigh over a 1000 kilograms or even more. Extremely large adult bull (male) elephants are known to weigh over 6000 kilograms.

Somewhere in Europe about 2 million years ago.

A vertical drill press is a large drilling machine that stands on a very heavy steel base. A 3" steel column extends up either about 6 feet for a floor model or 3 for a bench model. At the top of this column is an elongated box with the motor at the back, driving a shaft with a 4 tier pulley above it. The front of the box contains a hollow shaft with a spindle inside it. The spindle also has a 4 tier pulley on top. The hollow shaft can be wound up and down by the side control lever. lowering or raising the drill shaft and chuck, A belt between the 2 pulleys drives the spindle and the chuck connected to it's lower end. In the middle of the column, a table, usually about 15 " square can move up and down the column to adjust work height.

There are hundreds of types of chisel. Most of them are variations of the bevelled edge, narrow, flat fronted carving tool. Many have shaped cutting edges to allow more adventurous carving. Some are as small as a pen and have tiny blades.

The most common type of drill bit is the 'straight shank steel twist drill' .

Other less common but still much used bits are the Brad tipped bit for woodworking and the carbide tipped bit for masonry.

Resilient Bars are essential to help bring suspended timber floors into compliance with the building regulations for noise control through converted separating floors for flats. Used in connection with other sound insulating materials we supply, the bars will create an effective acoustic break between the bottom of the existing joists and the ceiling. If not fitted directly beneath the floor joists, Sound Reducing Resilient Bars can be supported by 50mm square battens screwed to the underside of any existing ceiling. (See installation instructions above). Plasterboard is then screwed to the corrugated section of the bar using our self drilling screws and for best results; two layers totalling 30mm thickness should be installed. Alternatively, two layers of 12.5mm plasterboard Sound Block can be used. A greater sound insulation improvement can be gained if a min of our Acoustic Mineral Wool (AMW50) is installed between the battens before fixing the plasterboard. When installed beneath an existing ceiling with AMW50 and 30mm of plasterboard applied, improvements in both airborne noise and impact sound would normally be well in excess of 300% this can be further enhanced if our Acoustic Membrane is sandwiched between the plasterboard layers.

Bobcats are the most versatile small machines I've ever seen, Mostly the come equipped as front loaders, but the standard Bobcats can take a small backhoe, a bulldozer blade, a post drill, a brushcutter, tine rake or a disc harrow and many other implements. - Tracked Bobcats are really good for bulldozing and there is even a mini 'Bobdozer' only 3 feet wide. There are Bobcat all terrain trucks and small utility trucks too.

Well a drill can be a training exercise to train soldiers or people (eg a fire drill), in this case it is not a solid it is an activity.

However a drill can also be a mechanism for boring holes in this case it is made out of a solid but may not be completely solid in cross section. For instance a wood drill is entirely solid but an oil drill is a hollow tube.

Obviously A router is NOT a saw. -To cut patterns use a jig saw or a scroll saw.

Heavy hex head has a larger bearing surface. For example a 1" heavy bolt 1-5/8" dimension across the flats. A finish hex bolt is 1-1/2". This creates a strong fastener. This is one reason many high strength structural bolts like ASTM A325 and A490 are specified a heavy hex pattern.

The head thickness is identical for both bolts.

These bolts are often found in industrial and steel connection situations. The stronger design is critical.

I have been unable to turn up any information whatsoever about anything called a 'steam coil hammer.' Is it possible you've gotten your terminology mixed up? I am hoping the following research might provide you with a satisfactory answer. [from dictionary.com] - a coil of pipe, or collection of connected pipes, for containing steam; -- used for heating, drying, etc. - A banging noise heard in a water pipe following an abrupt alteration of the flow with resultant pressure surges; A banging noise in steam pipes, caused by steam bubbles entering a cold pipe partially filled with water. And according to information found here Steam Coil Installation, Operation and Maintenance (PDF), if a steam coil is not mounted properly, water-hammer can be destructive to the coil(s) It is entirely possible that the term 'steam coil hammer' simply refers to the banging of steam coil pipes. I'm not sure this is what you were after. If not, if you can provide more details, perhaps I can do a little more research and find the answer you need.

You can use a standard HSS drill bit at a very low speed. Use it in a strong VSR drilling machine as the lead WILL grip the bit.

maybe because it is actually a square tube with chiseled edges with a drill bit in the center of the square tube-- The drill bit drills out most of the wood meat and the square chiseled tube slices down the sides of the wooden hole making it square thus creating a tenon hole.

My dad used them since the 1930's and always called them "sockets " or "ratchets"

There are all kinds of rope. Some is relatively useless and some are extremely good and durable. In rope, you basically get what you pay for. Cheap rope is inevitably junk.

Basically it because diamonds are made from squashed carbon particles which happen to be one of the most solid elements

I think it would be a safe bet that ALL Hilti tools and systems are patented.
