View Full Version : Organizing my 5C collets

My collet set runs from 1/16 to 1-1/8 by 64ths. I did have them arranged by ascending size but it was always a hassle to pick a specific one because often the size was difficult to read and even when I could read the number I had to do a bit of hunting.

My collet rack is 8 columns by 9 rows. I put all the 64ths together in the first 5 columns by 6 rows. So now (reading across from left to right and by 64ths) I have 11,13,15,17,19 . In the second row I have 21,23,25,27,29. The third row is 31,33,35,37,39, and so on down to 63. This leaves 3 slots in the last row vacant (63 being the last 64th) so that is where I put 5,7,9.

This left me with 3 rows under the 64th block. I did the same thing with 32nds: [1,3,5,7,9]; [11,13,15,17,19] … with 31 occupying the 6th column, last row.

In the 6th column I put the 16ths in ascending order reading down

The 7th column is by 8ths

The last column is for 1” and larger (again by 64ths)

This has made it easier for me to pick any given collet.

That wouldn't work for me.
My rack is 9 columns by 8 rows so I just put them in sorted by size and marked the rack under each collet.

I like your idea, Horst. I've been wondering how I could make selection from my rack easier. Thanks

On a semi-related note - what size are the holes in your 5C collet rack? Reason I ask, is I'm wondering if these racks work for R8 collets too? Or do R8 collets fall through the hole? I see 5C collet racks on Enco and other places frequently, but don't remember seeing any for R8.

5C is too big for R8

My 5C rack rack (auction purchased) is wall mounted, home made of plywood with the face at about a 20 degree angle off vertical. Size is marked under each collet.

They start in the upper left with the smallest collet (1/16 ?) in order of increasing size ending with 1-1/8" at lower right. Not sure (without looking) how many columns and rows, but about 24" square (from memory). Last I checked I believe all collets are Hardinge, collected over a number of years. Very easy to find the best fit collet when you have a random piece of bar stock. Simply try one, go smaller or larger as needed to fit.

I also have several purchased racks that hold maybe 20 collets in common 1/8" increments near machines. Another couple racks with hex, squares and emergency type. 5C step collets are randomly in boxes (I really should get a rack for them).

I don't understand the logic of Horst's arrangement.

Just a few days ago I made a collet rack for my R8 mill collets. I only have 1/8'-13/16" by 16 ths. so there are only 12 holes. I made it with 2 rows, the near row is by 8 ths and are the ones that I use most. The back row row is for the 16 ths, 3/16, 5/16 etc. I staggered their placement so that 3/16 in the back row is between 1/8 and 1/4 on the front row. Placement along a row is 1.75" c to c, the rows are 2" apart cl to cl. This allows my fat fingers to easily grasp a collet without touching it's neighbors. I marked the size in front of each hole.

My Weiler lathe has a factory supplied pull out 3/8" ply board on ball bearing drawer slides that is kept behind the storage compartment door. It has spots for a full array of C5 collets in mm sizes.

My collet rack can be seen here, post 1989

I don't understand the logic of Horst's arrangement.

The logic is this: by arranging the 64ths by 1-3-5-7-9 columns and rows by 10’s it makes for an easy grab. If you want a 47/64 you go to the #7 column and down 4 rows. All the 64ths ending in “7” will be in one column and all the 64ths beginning with “4” will be in the same row. That’s the heart of it.

Horst are you German?

I'd put the 1/16 series by the lathe and rest in a box or drawer somewhere. in my experience you don't need 37/64ths all the often so don't take up the prime real estate with it

I was biting my tongue to say something similar. I only have 1/8-1/2 by 16ths, and never craved more since I usually use them on rod stock in those sizes.

I arrange my collets in order of size, starting at 0.5mm and working up ;-)

I leave the collets in the cardboard case they came in. (Lyndex set X 32nds) The individual collets remain in their individual boxes which have LARGE FONT SIZE on the end flap.

When I select the collet needed, the individual box is returned to the larger case inverted with NO size designation showing , but readily identified and put to hand when it's time to return the collet to storage.

The collet boxes themselves are arranged in increasing order. Simple. And the collets stay clean. Even the seldom used ones. IIRC, there are some sizes that are still in the protective plastic wrappers. :-)
