R8 SHANK ER COLLET CHUCKS
R8 taper shank ER collet chucks are typically used on manual milling machines. The R8 taper end fits into a machine spindle and the ER collet nut is compatible with ER collet. ER collets are used to hold all the machine tools with a round shank. These R8 shank ER collet chucks deliver a quality significantly above average on market. The total indicator runout (TIR) is less than 0.0002". The MAX RPM on the manual milling machines is 8,000. The manufacturer of the collet chucks inspects and produces them in a highly sophisticated lab and factory. You can hardly expect the collet chucks from the other MFG to be of the same quality.
- Made of high-grade tool steel
- Hardened and precise ground

Design, Assemble, and Dissemble of ER Collet Nut
| Eccentric Design, ISO 15488:2003(E) | Assemble | Inspection | Dissemble |
| The inside of the ER collet nut is intentionally designed like off-centering to help mount the ER collet much easier. It is in accordance with the requirements listed in ISO 15488:2003(E). If it is made symmetrical, the ER collet with the diameter larger than the inside size of the collet nut cannot be installed. | Insert the ER collet into the nut at an angle. Lock it onto the eccentric groove of the collet nut and push it in. (Insert the cutter right after the step, before connect it to the holder/chuck/arbor.) |
Inspect the RPM of the ER collet, ER collet nut, ER collet holder/chuck/arbor, etc. | Take out the tool bit, press the end of the ER collet until the collet off the position. Push it out of the nut. (after take out the nut out of the holder.) |

Best Beef Tallow Cream I’ve Tried
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
Exactly what i was looking for, some of the beef tallow creams have a weird consistency which i don’t love wearing during the day. This cream is perfect for day and night. smells very good, application is perfect not greasy, moisturizing, soft. I love it! 10/10,
will be buying again 💗

Order it! Its great
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
I love the texture! Its silky smooth and light on the skin, no weird smell, very moisturizing. Ive used one of the containers for most of my pregnancy to keep the skin on my belly and hips moisturized. I add a few drops of organic frankincense to a nickel-sized amount of this balm and mix it together in my hands before applying. I use a clean q-tip to scoop out the tallow balm as needed too to be sure the rest in the jar stays clean, rather than using my washed fingers, to reduce accidentally contaminating the rest of it somehow. My skin has stayed so healthy thanks to this product. It reduces the itchiness of my expanding skin from the baby growing in my belly, and i think its made a positive difference in preventing stretch marks by keeping my skin hydrated as i use it almost daily and after every shower. I just got my second jar in the mail to use for this last month of my pregnancy, and I will probably use it for my baby when hes born too.
I also love that it comes in nice packaging, with a thank you note, very minimal plastic, and classy label. I dont think the jar is plastic either which i LOVE (pretty sure its glass container?) Thank you to the creators of this product. I kind of wish i could get it in a glass dispenser like lotion but i really dont care at the end of the day. Its amazing. You should try it.

Smells nice and light
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
Nice and creamy. Feels silky. Unfortunately, it does not help my knuckles very much. But I would buy it again because it is a good cream.

Excelentt
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1), Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
This product is really good, I researched it because it is the closest to human skin, and that was what it did help me repair my skin that was injured after an allergy of more than two months. I felt that I had lost the elasticity and shape of my skin, this fat stuck to me and made me feel safe again.

Will repurchase
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
At 56 years old my skin is pretty dry but this was still a little to heavy for a face cream-- but usable in a pinch. What it is PERFECT for is for your hands before you go to sleep at night. You know you're going to touch your face and pillow during the night so heavily fragranced creams aren't good at all. This is thick enough to make your hands and cuticles feel great but gentle enough not to cause problems if transferred onto your face.
