cutter grinder idea

I have used their service myself from time to time. A friend of mine did more regularly, running a HAAS CNC, and I remember him sticking with them for a while. Back then he had "batch" projects that would use up tooling, then he'd fix or replace things that broke, or sharpen what was dull, to be ready for the next lot.

Sounds good. I'll see if I can find an outfit like that around here.

I can't really see myself sharpening end mills myself. Heck, I can't even sharpen a drill bit decently. Sure, they work, but nothing beats a 15 minute trip to Varco for a brand new high quality drill bit. Saving up all my end mills and drill bits for an occasional trip to a sharpening outfit makes a lot of sense to me.

I've reached out to F&J Cutter Grinding in Brampton, Ontario. They responded right away, but they're on holidays this week, and she would get back to me with prices next week.

Sounds awesome! Please keep me posted. I'll keep looking closer too. So far all I've found is knife sharpening.

finding someone to sharpen endmills might be the way to go, especially if they are nearby. If anybody knows of a sharpening service in sask. let me know. I have 4 1" cutters that I think would be worth sharpening as well as a few smaller ones. Looking forward to hearing cost estimates.

OK, did some phoning around and found a sharpening service in Regina. 100 mi. away but he estimated $20 to sharpen a 4 fl. HSS 1" end mill. I thought it's not out of line considering the cost of new cutters. Going to give him a try.

For the Ontario guys I send all our cutters from work to RME in Guelph, and they always do a great job, at a fair price. They do coatings too, and have in the past put a nose custom radius on endmills for us along with laser engraved the size on the shank. First rate professional job. Never had an issue.

https://www.rmepvd.com/

We typically save up and send them a big pile to do, once or twice a year or whenever we need them.

Before using RME I had a batch of endmills sharpened by some guy with a cutter grinder in his garage. I could have done better with a bench grinder. They were completely useless, and he was a ghost in the wind about it. RME was only slightly more money and worth every penny.

For context I just dug through some emails for some #'s. A brand new 1/2" 4flute Niagra bright finish std carbide endmill is $27 (todays purchase), and to have that same endmill sharpened (dia/ends depending on requirements) is $14 (price from last order in late 2021).

I typically won't send anything below 3/8" to get sharpened as it's not really worth it, but have in the past as having undersized tooling is helpful to have around sometimes. This is for CNC work, so I can adjust offsets to dial in whatever cutter size I have.

Excuse me??? Where are you getting those 1/2" Niagara's from? KBC price is $91.91!!

If I told you I'd have to keeeel you lol. Just keeeeding.

They are not branded "Niagara" They are generic "made in USA", but I've heard from a few different people (tool vendors) they are in fact made by Niagara. The truth? I'm not 100% sure, and I probably shouldn't have said Niagara without knowing for sure TBH. I use them for general purpose milling of O1, and other tool steels, and they perform the same for my needs as the more expensive "branded" ones (except for a few) I've tried over the years, so I've never bothered to look elsewhere. For aluminum I use actual Niagara branded 3 flute high helix endmills, and they are amazing. More $$, but they are worth every penny for aluminum.

KBC price IMO is generally more expensive than what you can get from some industrial suppliers for generic things like endmills/drills if you have a decent volume. We have a guy that we've dealt with for a very long time for stuff like this as well as quite a lot of the other products/hardware we use. I'll ask him if he doesn't mind his name getting out there before posting it up. I know some of our other tool vendors don't like small/hobbiest accounts. We're not a big high volume customer, a small shop really, but it does pay to shop around and develop some relationships with vendors of frequently used tooling.

This is one of those endmills, that has been reground by RME on both dia, and length a few times now.

After typing this post, and looking at actual branded Niagara endmills I DO have in stock, I'm not so sure anymore. I know there are a ton of variables/models/lines etc, but there are far more differences....For all I know now, these could be rebaged chinese endmills, and he's been pulling the wool over us for years lol. Either way, I've always been happy with them.

Think I've figured out how to the center cutting grind in the Deckel clone. Bought the cupped wheel and will likely do a test grind this weekend.

Only working on Carbide, wheels for HSS bits cost more than those for carbide.

Once I've got it figured out I share the method.

Good stuff!

Do you think this pricing would apply to broken end mills too? What if I cut and pregrind them flat?

Did she mention minimum quantities and/or turnaround timing?

Are you gunna give it a go?

She didn't mention minimums. Yes, I think I'll send a bunch of them. I have 16-1/2" carbide endmills that need sharpening, as well as 3/8", and 1/4". Maybe I'll send them 5 of each size for now.
