Jacobs J422 Metric Tap Chuck Collet, 12.7mm - GW 9751
A collet is a specialized holding device used in machining and manufacturing processes to secure and grip a work piece or a tool in a machine tool, such as a milling machine or a lathe. It is a type of clamping mechanism designed to provide a strong and precise grip on cylindrical or round objects.
Features:
- Parallel jaw insert surfaces exert uniform, accurate gripping force up to three times greater than can be achieved with split - steel collets
- Each collet accepts and precisely centers a wide range of both decimal or metric diameters (within individual capacity ranges) to speed setups and increase machining productivity
- Durable one - piece construction. Synthetic rubber retains flexibility and resists deterioration from heat, coolants and cutting compounds
- Steel jaw inserts precision ground after molding process to ensure maximum gripping accuracy. Hardened for greater wear resistance than split steel collets
- Each collet bore is held concentric to the old Tapers, front and back, to minimize tier
- Automatically seals tool old To prevent coolant flow through thus increasing tool wear
- Seals collets and machine spindles to protect from abrasive particles and swarf

Actually helps dry mouth!
I’m giving this product 4.5/5. It works really well for dry mouth during sleep. I recommend starting with 1 tablet and adding a second one only if necessary. (I require 2 tablets at night). This is called “slightly sweet” and is relatively tasteless with a hint of sweetness.
During daytime usage, I’ve been using 2 tablets at a time. The only issue I have during the day is that if I can’t drink on a regular basis I get the white coating from the tablets in the corners of my mouth. I do think that this is the next best product to use when taking sips of water isn’t possible. Works as stated and easily adheres to your gum line/partial tooth. I place them in the back of my mouth and they are not noticeable to others. Added bonus, they don’t leave a slimy coating on your teeth the way a mouth rinse does. Product performs better than expected! If you have dry mouth for any reason please consider giving these a try!!! I wish I would have known about them years ago!!!

Works for dry mouth
Suffer from dry mouth and these disc size tablets stick to my gums, helping keep my mouth moist through the night. Brown side sticks to your gum. Contain xylitol so s little sweet. Dentist recommended them.

PRICEY and sometimes don’t stay in place!
These have a wonderful mild flavor, no mint burn, moisten your mouth for several hours, and generally always stay put, in fact if you want it out before fully dissolved, it takes a little effort with your fingernail, because they are supposed to stick and stay in place! ALSO, I DO NOT PUT ON MY GUMLINE LIKE THE INSTRUCTIONS SAY, I STICK ON THE ROOF OF MY MOUTH FOR DISCREET CONFORT!!
I really do recommend for DRY MOUTH!! I DO NOT CARE FOR THE SHARP EDGY METAL INDIVIDUAL PACKAGING AT ALL, but the bottle is very pricey!!
