Metal Work Hand Tools II
Driving tools, cutting/boring tools care and maintenance
Driving tools cutting/boring tools are tools used to make holes or drive holes and they are can also be used for cutting.
Examples are as follows:
- Hacksaw:
This is used in cutting metals and other materials like fibre and plastics. It is composed of a handle, a frame, and a blade.
- Scraper:
This is used to produce a surface truer that can be produced by machining. Scraping is a process of removing small amounts of metal from specific areas to produce an accurate surface. It is a long and tedious process. Scrapers are made of high grade hardened and tempered tool steel. Carbides are sometimes added to the tips to make them last longer.
- Chisel:
Is the simplest form of cutting tool. It is made of heat-treated steel with the cutting edge shaped differently for various chipping requirements
- Screwdriver:
Instruments designed to drive in and take out screws. The two most common types used in the shop are the standard screwdrivers with a flat blade and the screwdriver with the crossed tip to fit the recesses of a Philip-head screw
Here are some tips to take good care of tools:
Keep them Clean:
Always, all tools must remain free of debris and dust, which can cause damage over a long time. Cleaning your tools will take only a few minutes. It is well worth to spend time cleaning the tools compared to the cost of repairing or replacing them.
Inspect and Repair:
One must inspect and do the necessary repair for the following:
-
Splintered, cracked or loose handles:
In case a wooden handle is damaged, it is prone to breaking during use, with the potential to injure someone. If the handle is not damaged too much, you can sand it down just fine. If the handle is too rough, first sand against the grain. Sand till it is smooth enough to run your hand along with it, without sensing splinters or chips. Complete the process with a coating of linseed oil. But if there is heavy splintering, you must replace the tool.
-
Mushroomed heads on wedges and chisels:
A mushroomed head is just that. It implies that the striking edge which must be sharp has become malformed through use. When you use a tool in this state, the head can shatter on impact. Luckily, you can solve this problem by keeping tools sharpened. It is good to sharpen them whenever you notice a problem. Make it a habit to sharpen tools at least once every six months.
-
Rust and corrosion:
Based on the level of rust or corrosion, it may be unsafe to use the tool. Try to remove the rust by yourself or simply replace the tool. Getting rid of rust is quite easy in case there is no great damage.
-
Proper Storage:
Cleaning your tools is of no use if you don’t store them properly. Based on your needs, a simple toolbox will suffice. In case you own a big collection of tools or use them professionally, a great option is a metal cabinet. All tools must be sorted and organized and replaced in their stipulated storage area after use. This way you can not only access them quickly but also keep them safe.
Ideally, the tools should not rub against each other when stored. Some companies have designed storage systems to cater to this need. Keep all tools in a dry area, safe from moisture, direct sunlight and dust. Sharp tools like chisels must be stored in a holder to prevent injury. Also, do not leave tools in the work area for fear of posing as a serious hazard.
In our next class, we will be talking about the Maintenance of Tools and Machines. We hope you enjoyed the class.
