What is this KD Tool?

[Sandxssun]

I picked up this set of KD tools at an estate sale. The largest bit appears to have a model number of K-D 3032. The rest have lower numbers. Anybody have an idea of what they are? I came across one website that mentioned they might be some type of brake drum adapter. But, I’m not so sure.
any help would be greatly appreciated.

adjustable reamers. probably for rebuilding wheel cylinders & master cylinders

Yep, adjustable reamers. Not sure about brake work tho.

General use pilot reamers for misc applications: king pin/spring shackle/pitman arm/piston pin/water pump/and tie rod bushings

I agree on the brakes. my mind was on brakes when read the original post . brake parts would be honed at best I imagine

They are definitely some sort of reamer. As for the intended application, it will depend on the selection of sizes. I would rule out heavy duty suspension and steering parts if the sizes were small.

Delete, my mistake.

When I don’t know about something, I usually don’t say anything. I have, however, made erroneous assumptions in the past.

Those are adjustable reamers. They can be used in just about any application requiring close tolerance fit. Common applications are king pins, piston pins, transmission bushings, etc. Tthey are meant to apply to a range of size vs. a dedicated size reamer. In some applications, reaming is enough, in others fine honing may be desirable after reaming.

I can think of no application that these would be used on brakes, and certainly not as a puller.

Never mind had my KD part number incorrect. Here is an actual picture of the reamers https://www.hobby-machinist.com/threads/sharpening-adjustable-reamers.97356/. My apologies. The KD part number for the drum removal tool was 3020 not 3032. Looking at pictures on a little phone screen is probably a bad idea as well, especially at 7 am in the morning. Thank you @Ricky Joe for being very polite regarding my (rather large) mistake.
