Deburring Tool

[rossbotics]

DeBurring tools are very handy and useful to have, they come in a multitude of shapes and sizes, I have been using for years these disposable units with a B-10 blade, B-10 blades will work in holes, inside radiuses and straight edges which covers about 95% of my deburring, any other deburring gets the old file treatment or a scraper.

I bought this new deburring tool about three months ago which included a handle (of course) and a B-10 blade, it had a spring loaded quick release mechanism for changing the blade which was great, it worked fine for a while then I noticed a last week the blade was starting to get loose in the handle and working its way out, well come to find out the whole dang thing was made from PLASTIC, I paid over $25.00 for it thinking I was getting a fairly descent tool, this is what intrigued me to make this tool, they just don’t make things like they use to, even name brand tools are made in china anymore.

I wanted to make this tool with some what of a quick release end on it, so I came up with this threaded retaining cap idea which contains four 1/8” hard steel balls, those balls fit into a radius that’s machined onto the B-10 blade, this is what holds the blade from coming out of the handle and allows the blade to rotate freely, all you do is insert the B-10 blade in from the bottom of the retaining cap and drop four 1/8” hard steel balls in from the top of the retainer, (just don’t drop your balls on the floor J) the balls locate themselves automatically around the radius of the B-10 blade, inside the retaining cap looks like a ball bearing when assembled, simply screw the retaining cap onto the threaded end of the handle and your done, it swivels nice and smooth and you can’t push it in or pull it out, to change the blade you just reverse the process stated above.

The tool was constructed from 4140 steel, hardened and tempered, NO PLASTIC, the handle has a hex milled on it for a nice grip, the handle also has been drilled out to 29/64”Dia. X 3 ½” Dp. and taped ½”-20 for a cap, this also relieves weight in the handle and acts as a storage department for holding extra B-10 blades, this tool works as intended and hopefully my problems with a deburring tool is over.

Below you find some photos of the machined parts and the finished tool

As always thanks for looking

And happy machining

Doug,

Very nice design, fits well in the hand and has an easy, quick release blade collet.

Thanks for posting this and providing the details.

Now I need to go have a look at mine. haven't used in in a while for some reason I only use it on aluminum or brass and haven't machined any of either in quite a while
But if I remember correctly mine has an aluminum handle don't remember how the blade is changed but I really like your design.

Frank S,

I think Doug's design is very sturdy and the quick release head makes it so easy to swap deburring cutters of many different styles. I made a deburring tool from an old Gillette Sensor Excel razor handle ( http://www.homemadetools.net/forum/m...r-handle-18962 ) but I didn't know how to make the quick change head. Doug's design solves this problem and is a significant improvement over the plastic versions. I think Doug has a great design with the four ball bearing quick release head and all metal handle.

I like the quick release as well. just never paid much attention to mine since I hardly ever use it

A couple of years ago my grandson gave me this Noga deburring set as a Christmas gift ( https://www.mscdirect.com/product/details/67294520 ). It came with a decent quick release aluminum handle but I wanted to make a dedicated handle for the Roto-Drive Countersink. The Roto-Drive Countersink is very useful and quickly deburrs the hole edges of drilled holes without having to swap the drill for a countersink. I use this more than the dog-leg deburring cutters.

Nice work Doug, I have a German made VARGUS one that I have used for many years and would not be without it but when it retires I will copy your design.
I have found that the blades can be sharpened a few times with a diamond file (I know,how mean can you get).

Very nicely done, Doug. You certainly won't break that one easily.

I have a number of the Noga style deburring tools and use them frequently on my larger scale projects.

However, when one gets into the world of miniature engine models and such, that style of tool simply isn't usable; it's just too big for the tiny holes encountered in model work.

What I use are a different style entirely. Although I purchased mine, I thought it useful to show them here. Many folks will never have encountered the style; moreover, having seen them, making one's own version is certainly a possibility so there's a vague homemade tool connection.

Each tool consists of a fluted handle with a small disk of carbide attached at either end. In use, a disk of the appropriate size is seated on the hole periphery and the handle is twirled between the fingers while applying slight downward pressure. The sharp edges of the disk quickly and neatly remove burrs around the edge of the hole.

The tools are Swiss-made and available from Gesswein...

Precision Deburring Tools

Very interesting, and thanks for the link. We have several antique stores that have different booths inside and one person's focus is tools. Especially machinist tools. Last time I was there I saw one of the special cross drill deburring tools that was in your link and of course had no idea what it was. There might have been one of the small tools like the ones in your pic and I wasn't familiar with it either. Nobody in the store knew what they were so I passed.

Just out of curiosity, can you do edges with the round deburring tool by wedging it against the handle and the round cutter against the edge to be deburred? Or are they strictly for holes?

[Frank S]

I just has a look at mine. Like I said I've had for for years and it still has the original cutter in it I never noticed until just now how the quick chuck works. It is spring loaded so just push it up and it opens the Brand is General the body is hex aluminum. most of my deburing is done with a 2" diameter cone grinder or a 60° tapered champer bit but a lot of the stuff I do any more doesn't require much precision attention
