Internal circlip grooving tools

[Kram]

What tools are you using for internal circlip grooves? In theory I could grind something in HSS or carbide, but I tried that once with a parting tool and failed several attempts miserably. Its a similar task..

Clip size is about 1mm - 1.5mm thick, should cleaance be added or, should a groove width be tight?

Small clearance and ideally edge relief

Buy an internal grooving tool, if it's more than a one off

For a lathe, I'm assuming? A simple boring bar type tool ground suitably.

I have made my own from HSS over the years but when I had a few to do when making my VDI turret I opted for a bought one. It was for the WNT mini boring bar holder which I already had so it was cheap enough for me, under £20 if I recall.

Sandvik 154 but they don't make them any more. they do a triangular insert with a hole through the centre that bolts to the end of the bar.

Get yer grinder out



3mm wide facing camera (ali/brass only), 1mm wide on the other side.

Sandvik replacement of my inserts is basically a threading insert.

P Horn tools often come up cheapish on ebay

Easy enough to make yourself, and use an old centre drill for the cutting bit.

Plenty of info from the circlip manufacturers online about the correct diameters, widths, tolerances for all types of circlips. Similarly for where to place the groove correctly to retain your components, bearings etc.

Where did you find that. It was the one thing I really struggled with while making the secret present for @Onoff recently.

Good thing about the WNT ones in comparison to others (P Horn etc) is they are just a cylindrical shank with a flat, so easy to make up a holder.

Yep, PH and sandvik sting you on the holders

This is what I used them for, wedges for the VDI turret I made, hole is 18mm dia.

not tried the internal ones, but the external didn't flinch when I had to turn a circlip groove in a (very hard) outer bearing race - nice orange-glowing curlies and a clean groove.

If the ID is big enough, it is possible to get grooving inserts for laydown threading tools (e.g. the ones that take ER16 inserts). Vargus' website will give you an idea of what they sell.

I bought an IR11 screwcutting bar off JBTools on eBay and it came with a grooving insert.

I've silver soldered an old parting insert onto the end of round HSS blank and ground freehand with cheap 6" diamond discs of ebay, worked well.

I looked. Could find 1.5mm or 2mm but nothing in between.
