Construction Tools

The function of a drill is make clean holes in objects.

A keyhole saw or a sabre saw will do that.

Yes, you can. I have done so many times. Just be sure to reduce your drilling speed.

I use a brad tipped drill on oak and other hardwoods.

When the tool is unplugged and a warning sign placed to NOT plug it in.

It is a mitre saw that only angles one way.

Tungsten is a major component in those drilling bits.

Geologists use drill bits covered with small diamonds because diamonds are the hardest natural substance and can effectively drill through hard rocks in the Earth's crust. The diamonds on the drill bits help to create a clean and precise hole without getting worn out easily compared to other materials. This allows geologists to obtain core samples for studying the composition and structure of the Earth's crust.

The blade is places so teeth cut on the push stroke.

HSS-R and HSS-G both belong to tool steel of high speed but difference is primarily in the production technology. HSS-R is rolled in warm state and sharpened at the end; HSS-G (ground) is cut in their shape with the help of diamond tools and cooled during the process.

HSS-R should be expected to be more elastic, and HSS-G more hard. Use HSS-G for more precise work because they are better centered generally. Use HSS-R for lower price and little rougher work.

If not accompanied with other designations on tool (like Co for cobalt, or Ti for titanium, or something else) both HSS-R and HSS-G are suitable for drilling the steel of similar strength, about 900MPa. Practically if no other designation is on the tool abandon using them for hardened steel, but instead for ordinary carbon steel, ordinary HSS sections, brass, copper.

Not damage it, but not the best lubrication either.

They are made in China.

I have used tenon saws many times and have never seen any danger involved. The teeth are small , the saw is hand powered so what possible danger can you envision.

You can drill holes in aluminum with a drill as long as you have the proper drill bit. Use a regular drill bit and keep speed moderate.

Yes, you can drill polypropylene. Use a regular drill bit and keep speed about mid range. Too fast melts it instead of drilling and too slow may catch the edges of the bit.

I spray the working parts with Lithium grease once in awhile .

Because the friction of drilling heats it up.

The function of drill parts is to collectively make the drill a precise and efficient tool.

Chalk lines are to establish a continuous straight line for things like laying tile or setting bricks.

For a start, there are 4 sizes of actual Phillips screwheads. There are also a number of very similar screwheads to Phillips, these have been made to improve the 'slip' that is common with Phillips heads.

Because that's not what they're intended for. It's dangerous to use a tool improperly.

40 parts gas to 1 part oil.

A back saw is a type of hand saw with a stiffened spine along its top edge, which helps maintain a straight cutting line and provides greater control. It typically has fine teeth, making it ideal for precise cuts in wood, particularly in joinery or cabinetry work. Common types of back saws include the tenon saw and the dovetail saw, each designed for specific woodworking tasks. The rigid spine distinguishes it from other saws, allowing for cleaner and more accurate cuts.

If you are hoping to insert a 5mm anchor, the hole must be close. I would drill a 5mm hole.

Both Home Depot and Lowe's sell quality drill press stands, online or in-store. They feature a variety of brands and styles, perfect for amateur or professional woodworkers.
