Solid Carbide End Mill

I broke a tap in the aluminium crankcase of the 5 cylinder rotary engine that I have been working on and after looking online the recommendation was to machine the tap out using solid carbide cutting tools. I did some searching and ended up back at one of my favourite suppliers arceurotrade.co.uk and saw that they were selling Solid Carbide end mills at around 8.50 each for the 3mm ones.

Review


Not convinced about solid carbide end mills. This one lasted about 5 minutes of gentle use. It did do the job it was asked which was removing a broken tap, but the end mill did not survive.

I finished the job off with the normal TiN coated HSS end mills that I use.


Price: approx 8.50 for a 3mm end mill

Conclusion

Not as robust as I expected. It did most of the job of removing the tap and so worked, but did expect it to remain in one piece.

I would say rather expensive and would think twice before buying a second one.

Available at arceurotrade.co.uk

This end mill has now been turned into a point for a home made scriber - a great recycled part.
