Soft-toss is when you throw a softball in a small arch in front of a batter who then hits it into a net or fence. This helps to develop muscle memory of the correct way to hit a softball. It also helps with developing more bat control and more power.
Use a brand-new bit for metal mounted on a hand drill (not electric). Slowly rotate the bit in the lead, which is a "soft" metal.
I may be wrong on this, but I think an opal is one of those stones you set and not drill. It is a very soft stone and damages easily so it will crack if you drill it.
Drill a hole and use an appropriate rawlplug and screw.
You can drill through tile, but doing so would most likely crack and break the entire tile. It is not recommended to drill through a tile, unless it is a soft tile, where the tile will not break if drilled through.
A wrong type of drill bit will seldom ruin a project, but can cause small difficulties. For instance drilling fast through soft wood with an HSS drill bit will cause splintering coming out. Drilling fast into steel with a drill bit intended for wood will severely blunt the drill bit.
Depends on what materials they are normally going to be using it on. Softer materials, such as wood products or soft metals, I'd suggest to get a drill with high rpm's. But if they are going to be using it to drill hard substances then I would direct them towards a drill with a higher torque, as this will help to avoid the drill freezing up or skipping on the materials.
This is not a question - just a list of sports-related words !
A drill operating at ultrasonic frequencies (>20 kHz) will usually employ a hard abrasive powder to actually do the drilling. The drill bit (which could be soft) vibrates back and forth at a high frequency, and grinds the substrate away with the abrasive.
