Vargus deburring tools are widely used in engineering and manufacturing processes and there are many specialist tools provided by Vargus that I have looked at over the last few months. But I got a bit of a treat when the Mango II Kit arrived for review – this 23 piece kit is an excellent all-rounder because it contains pretty well all you will need for the general workshop that routinely handles a range of metals and other materials like plastics too.Vargus tells me that the kit has all the tools needed to handle over a thousand applications. At first I was a predictably sceptical, but the more applications I tried it on the more the applications mounted up, so I am sure that users more expert than I would easily pass the thousand mark.
To quote just a few applications from the blurb: - “deburring straight edge, hole-edge, hole-back edge, cross-hole both edges, sheet metal, flat surfaces and hole inner surface. The tools inside will cover a range of materials that includes steel, aluminium, copper, brass, cast iron, stainless steel and plastics”. The fact that it is all beautifully contained in a small but robust plastic case with decent catches, so it won’t open up accidentally in transit, makes it also an ideal kit for the fitter on the move. Maybe someone who doesn’t necessarily know exactly what materials or challenges they are going to be handling each day, so needs a bit of flexibility in the toolkit department.
The case is neatly divided into separate compartments to hold each section of tools, handles etc and the lid is lined with triangular-formed foam so that when the lid is snapped shut, the tools inside don’t move around and get confused with each other.
I started by looking at the handle provided with the kit – this is made of a hard plastic with inset grippy rubber moulding and a strong spring-loaded collar on the base. The handle can hold the five blade holders supplied with the kit so that they can be each be used with the tools that fit them and also can be adjusted for length if necessary. Simply find the arrow on the collar and line up the milled part of the blade holder with it. Pull back the collar and insert the blade holder to the depth you want and you are nearly ready to go.
The five blade holders are needed because each type of deburring tool needs to be held in a different way for maximum performance.
A closer examination of the blade holders shows that they are well made with a few little details on them proving they were designed by people who knew what they were doing. For example, the hand countersink tool has a pair of parallel flats milled on it so that it can be removed easily with a small spanner, as the action of use will inevitably tighten the countersink onto the blade holder.
The other four blade holders are designed to hold various deburrers and so vary in detail.There are two bladeholders with steel spring-loaded collars that hold the deburring tools that need to move freely on the edge of the work to work effectively. A small ballbearing holds the tool firmly so that it won’t come out of the holder, while also allowing it to move freely.
The two toolholders are needed because the shanks of the deburrers are two different lengths to allow flexibility when doing different tasks.
The toolholder that fits the triangular carbide tool used for scraping surfaces and deburring sheet material has a small screw to hold the tool in place. The hex key needed to tighten the cutter in place is provided and the small lugs on the toolholder prevent the cutter from moving around in use – another example of thoughtful design that makes the Vargus tools easier to use and very practical.
The tools that I hadn’t used before were a pair of triangular file-shaped High Speed Steel scrapers. With their triangular pointed shape they were easy to insert into small cavities to scrape away residues etc and the toolholder designed to fit them is a model of simple practicality – the scrapers are simply screwed into the end of it and they are ready to be used.
The kit contains nine hook deburrers that can be used on straight or curved edges and also used clockwise or counterclockwise. A couple of the hooks have an offset and are a bit extended so that they can reach odd places and there is also a tool with a sharp hook that will deburr both sides of a hole simultaneously.While I tried as many of the tools in as many situations and as many materials as I could find in my workshop I knew I would never be able to reach the limits of this kit. All the tools worked as I expected, and the more I practiced the better I got at using them – there are a couple of techniques that pretty well ensure a good result every time – like not stopping in the middle of a stretch for example. However, an expert would, I am sure, appreciate the range and flexibility of the kit.
At a push there is room in the case for another Mango handle so that users can simply put down one tool and pick up another. Of course, expert users would also be able to buy other cutters as needed for different applications, and there is also plenty of room in the case for those too. With a list price of £121.42 it’s a lot of kit for the money. Remembering also that it will only be the deburrers needing replacement, depending on how much use they are subjected to.
There is also a slightly smaller and cheaper version of the kit called the Top 3 Mango II starter kit that contains only the three most popular styles of blades that would keep the likes of me and my deburring needs more than happy.
