Some tools are safe enough when used as intended, but can turn harmful when pushed past their limits. Take for example, sockets on impact wrenches. Those lighter shiny chrome sets are great for hand-tools, but impact guns deliver much more punch, which is why you’ll never see a pro tech reach for anything but a properly made impact-socket when the powerful air-tools come out. Sockets not designed for impact use will crack (if you’re lucky) and can sometimes shatter, throwing sharp metal shrapnel in all directions.

However, what you should never get – no matter how little you spend – is something that may injure, maim, or even kill you.

The insert geometry, tolerance, dimesions, and terminology are all based on the ISO standards. Other countries such as America (ANSI) and Japan (JIS, CIS) have their own standards but they are all based on the ISO standards.

I purchased a used home-built CNC Milling machine to cut aluminum and brass. It has oil pump and tubes going into rail bearings and ball screws.

"Inserts" or indexable inserts are used as the cutting edges for cutting tools such as tool holders for turning and face milling cutting for milling.

Drive-on ramps can also be a gamble. We’ve covered these before, but their potential danger bears repeating. Those thin metal wheel ramps designed to position a vehicle axle high enough to work under can be a real risk unless you are perfect in your approach, know exactly where to stop, have the proper wheel chocks and have the benefit of a solid driveway to place them on. A far better choice would be a properly rated set of axle stands, a floor-jack, and the knowledge to know where to place them.

The cutting edge angle is 80° and therefore offers high cutting edge strength. However due to the short cutting edge length the depth of cut is limited.

If you’re a dedicated shade-tree mechanic, you’ve likely got a serviceable tool set in your garage but are always on the hunt for something to make difficult jobs easier. Prices can sometimes be a barrier, as specialty tools for automotive repair can run high. Even a professional just starting out can easily have over $10K invested in a modest tool chest and tools, and some experienced veterans will easily have 5 or more times that figure worth of equipment in their work-bay. There are less expensive alternatives, but as with most things in life, you get what you pay for.

The square insert has 4 cutting edges per side. If the insert is negative then it is possible to use a total of 8 corners. Thus making this style of insert very economical. The insert has a cutting edge angle of 90° so it has high cutting edge strength. However, the square insert needs a side cutting edge angle to machine and and such can not be used for machining a right angle.

The top of the most-likely-to-injure list has to be the infamous hook-style suspension-spring compressor, needed when installing new struts. A set of metal hooks are attached to a threaded rod in these potential mechanical-maimers and when the rod is turned the hooks compress the spring. The problem is there’s no safety cover to hold things together if the hooks slip when the spring is released from a strut assembly by removing the top nut. This brings the risk of an upper strut mount flying towards your head with enough speed and force to crack your skull like a coconut. Your options here are either pay a shop to do the spring transfer with the right equipment, or buy an assembled spring and strut unit, or at least have your health insurance and will up to date.

The round insert offers the strongest cutting edge. Additionally, due to the large radius it provides the best surface finish. However there are a few disadvantages.

For example, due to the long cutting edge the chips developed are relatively wide and such difficult to break. Also due to the large contact area and the long cutting edge length, the load on the insert increases. This can result in vibrations when machining small or thin walled objects.

This insert can be used for external machining and facing, and such is often used on CNC lathes. It is the most commonly used insert.

The triangular insert has 3 cutting edges per side. It has less corners than the square type, but is effective in machining right angles and for copy machining (copying). This insert has a cutting edge point angle of 60° and therefore it has less cutting edge strength when compared to a square insert.

He began his writing for the Ottawa Citizen where he penned the ‘Ask the Expert’ column, answering motoring questions for thousands of readers. He took his pen on the road, so to speak, and offered similar consumer advice through several smaller news publishers over the years.

Round inserts are best suited for machining that requires high cutting edge strength, such as interrupted cuts, removing scale, and when machining cast iron as the chips do not elongate.
