The name Colaba is a corruption of the original name Kolabhat, meaning a Koli village in the Koli dialect (a variant of Marathi). The Kolis, mostly fisherfolk, were the original inhabitants of the group of 7 islands now known as Mumbai. The name Mumbai itself is derived from Mumbadevi, the patron goddess of the Kolis.

But people often get confused while choosing the correct carbide insert as it comes in different size, style, grade, geometry, angel, specification,  and these grade, specification , size are encoded in its Product Code kind of Random collection of Letters and Numbers.

You must have heard of carbide insert comes with a unique code TNMG160408 CNMG120408 CCMT09t304 VBMT160404 , you must be thinking what are these codes to do with insert specification.

Inserts are used for different application like Boring, Turning, Curve, Grooving, Milling Etc. Every insert codes has its meaning  in itself , Now we will go step by step and understand the decoding.

To cut metal profitably, there are in fact only 3 parameters that you really need to understand to select the right insert for your application. These are the numbers marked in red in the above example. The others, like the insert shape and cutting edge length, are automatically decided based on the holder that you are using. In the table below, you have to use your brain only in selecting the parameters where there is a brain in the row.

Carbide Inserts are replaceable bit that is used in a Cutter for working on different alloys such as Cast Iron, Aluminium, Steel  in CNC Machines / Lathe Machines/ Milling Machines (Computerised Numerical Controlling Machine).  The main advantage of Carbide Insert is it works faster and that result in more finishing of the Components.

Thankfully the hotel was about a km. from the touristy part of Colaba, and I got to see the view towards the Gateway instead of the ‘from the Gateway’ view that I would have seen as a regular tourist. I went camera-mad and got these pictures, mostly at dawn.

Looking at the boats tethered to the shallow sea bed, I wondered how come nobody ever stole any of those expensive speedboats. Must be easy to just start one of them and drive (is that even the right word for moving a boat – I wonder what is the right word ?) it off to some neighbouring town, and nobody would ever know. Good thing I can’t swim and barely know the front end of a boat from the back (I only recently learnt that they’re called fore and aft respectively) – might have been tempted to steal one of those posh boats otherwise.

Some time back I stayed in a hotel in Colaba in Mumbai, very close to the Gateway of India, at the southernmost tip of Mumbai.
