I have a Keiko hammer drill and the chuck screw broke. The local hardware store doesn't carry reverse screws. Couldn't find anything on the drill. Visited ereplacement parts and they couldn't fine anything. Contacted the company and their response was we don't make that and have no parts. No I just need the screw dimensions. Same response. Took my half of slug down to home depot and figured out is was a 10-32 or M5-.8. Couldn't find anyone who had both of them and anyone who did have both said one of them was on back order. Until I found Kauffman, not only did they have them in stock, but it got here in a couple of days. Wife was happy I could finally put up the hose reel today. I was happy to have my hammer drill back.

Needed a left hand thread bolt for a very old Delta sander. Searched every where and couldn't find one. Found Kauffmans on google and called them. They were so friendly and helpful. They had the bolt I needed and shipped it out immediately. So happy to have my sander back in action. Next time I will look to them first for parts.

I am very glad I bought from here, it was the lowest price I could find, the shipping was fast, and it was the exact part I wanted. If I ever need any odd parts again, I'll be sure to look here.
