Thin grooves/ parting tip

(1/1)

Swarfing:
Guys

I needed to make a very thin groove on a differential drive coupling on my sons RC car. This needed replacing because it was broke. The groove was for retaining a circlip that was only about 3mm accros. After pondering what i could use decided to grind down a Stanley blade. Put it into my parting tool holder and it worked a treat. I even parted the piece off afterwards and it stayed sharp enough to finish off a couple more. It works fine at slow speeds on mild steel, aluminium and even worked on a piece of semi hardened steel.

Hope this is helpful

That's neat.

 I've used a hacksaw blade ground with top rake on the teeth edge to cut thin grooves, but a Stanley blade is probably a bit stiffer.

Another variation which I have recently used is a blade from my power jig saw which at 1mm is thicker than a standard hacksaw blade. I also used one of these blades as a form of broach to cut a keyway in a gear wheel.
