Quiet grinders

K6 silent is still available, as is the Wega equivalent (6.4 silent) - but it is only available in doser which I dislike. Can't buy a high end hand grinder for love or money right now - no stock of either pharos or HG One.

The production on the pharos has slowed down , you need to check each day for in stock .

Should not be a problem getting an HG one, only took 4 days to get here just need lots of coin....

Hildy

HG One is out of stock for another two weeks at least...

Interesting.... Be prepared for a long time to season the burrs if you get the TIN coated ones. Other than that, it is a good grinder.

Tin is a soft semi precious metal that is used to rustproof other metals Tin is also food safe - hence it's use in steel food cans coated in tin KK

eggbert

I think he meant Ti coated

Hildy

or rather, TiN - titanium nitride - which gives a particular gold colour you can sometimes see on drill bits. Good for cutting surfaces.

Yep, titanium nitride PVD (physical vapor deposition) in layman terms is a food grade barrier metal applied to a surface for purposes of hardening and protection. It is commonly used on cutting elements where edge retention and corrosion resistance are desired, and will extend the lifetime of a cutting part three to five times. I can't decide yet if it was a good Idea or not, being almost beach-front I need all the corrosion protection I can get, But seasoning them is a long slow process....

There is PVD and then there is PVD and not all PVD is the same... Good quality drills as used in most machine shops are not; yet you will see many a set in Burnings but am sure many are just cheep plating. Quality PVD is an interesting process and as to food safe..... Not unlike the term ORGANIC OR GF; in the large majority of cases it is nothing more than clever marketing and people making assumptions and drawing long bows. I am happy with the placebo effect, but when some charge significant $$$ and know full well the product is only good for the placebo, that is questionable. As to a Quite Grinder, they are all noise generators; and without a barrier to trap the noise they can not change the physics involved and thus E=MC² still holds true. Cheapest is a set of disposable ear plugs :rofl:

so true, I have used many a cheap drill bit with gold coating that we crap

My good quality set (Suttons) are not plated, merely HSS. The lathe interchangeable cutting surfaces are, though.

I can't get earplugs for the dog - who likes to bark at both the vibe pump (getting a rotary pump machine), steam wand (drink black coffee), and grinder (what can I do?)

Drill bits can , and are , resharpened. modern lathe tool bits are disposable... (probably TiN coated Tgn Carbide) No point in coating a drill if the coating is going to get removed during sharpening, whilst the coating on the disposable tool bit will extend it life considerably
