It seems that every hole I tap ends up a little loose compared to threaded holes in mass-produced products. I don't know why. I use the right size drill, use...
Thanks, Fig. I think this explains why my hardware store taps produce loose threads. Like everything else in the shop (and in life), the good stuff costs...
... considering the markups on hardware store stuff, you might be surprised to find that the taps you want *might* be equivalently priced. IIRC, the rating...
One of the interesting things I noticed about my mini-mill, and I expect it is true of all of them, is that the x- and y-axis dovetails don't actually slide on...

I am new to this and have a very simple question. I am confused. I purchased a Sieg mini-mill from Cummins tools. It came with a regular drill chuck. I want...
I prefer R8 endmill holders to collets. Collets can be tough to temove, if stuck. I'd start with the ones for 3/8" and 1/2" end mills. These are the ones...
... You're right. The chuck is held on by a friction fit, and the taper is designed for axial (up/down) forces, quite frankly, mostly those that push the...
I prefer using R8 collets over end mill holders. I use a lot of 1/2" end mills and some larger than 1/2" that have 1/2" shanks. I have a drill chuck with a...
Jym, Your Cummins mini-mill came with a drill chuck with an R-8 arbor. The same chuck may be used on a lathe, if you have one, by swapping the R- 8 arbor ( it...

I need to do some drilling with small bits (0.50 - 1.60mm) and need collets small enough to do this job. Currently, my smallest collet is 1/8" . . . the set I...
You can get universal collets also sometimes called emergency collets which are just collets with no hole for a tool to fit into. With these, you make your own...
... The ... the R- ... Better suggestion: First remove the chuck and arbor from the mill using a wrench. Be careful not to let it fall and be damaged. Hold ...
What type of taper is your spindle? ER spring collets get down to 0.020", but only in the smaller sizes ER11 and 16 according to my old J&L catalog. That...
Charles, Sorry to hear you got a bad chuck. I guess it's the luck of the draw. But, then, we know that the quality control of these tools is not consistent. We...
quote "So maybe check the chuck before you chuck the chuck and write a check for a new chuck, eh?" Wow, did you almost 'choke' getting that out! I had a very...

Are you an Agent Provocateur sent by Yahoo to spice things up here? This question probably sets off more "animated" discussions than any other. My answer: end...
Rick, My mill has an MT-3spindle taper. So, where do you get the small drills to fit this. Someone suggested I get some 1/8" shank drill bits since my...

I've never heard of small dia. drills with 1/8" shanks, so I can't help you there. The small drills I use are from a standard Number drill set #60 (0.040") to...
Looking at putting powerfeed on my HF mini mill. I was looking at doing something with a stepper motor but by the time you get a good enough stepper and put on...
... Printed circuit drill bits. Solid carbide, but fragile because of it. Good for boards, though. HF has a "kit" with random sizes. They also (at times)...
