Best Annular Cutter? Fein, Milwaukee, DeWalt, Euroboor, Hougan, Hermes, S&F, Evolution, Steel Dragon

I've used a lot of Slugger and evo mag drills and bits, had purty good luck

The last couple of times I used a mag drill with an annular cutter, I needed to drill several holes in an 18 wheeler frame & instead of using cutting oil, I put my water hose at the bit & let cold water run over it while cutting the hole & it cut 18 holes on the same bit & the 18th hole cut just as good as the first one

I love your reviews but its hard to say how they would stand up overall. I know you had to come up with a process to make it the same and even but this is not how i use these cutters.

The constant pressure while cutting is not really something i would do with these. I let them eat pull out then back in, also i add fluid more often and if the cutter is covered in chips i clean it out.

I understand and appreciate the tests you do, seriously one of the best and fairest out there

Thank you for the video. The copperhead chips are dramatically more desirable in my mind. That alone makes it much more interesting than the others.

As a construction worker i used many brands . The best machines ive used are the Fein kb series and the atra ace by nitto koki (hikoki) the worst machine is euroboor it wears down fast and a lot of play on the rails wich is gonna break the drill bits. I use the euroboor cutters and phantom cutters because i live in holland so euroboor is 15- 20 euro per cutter.

Now every hole I see has a rough edges.

Love the chips on the copperhead!

Gotta agree with themep, I didn't know of these type bits...pex

Test for best mag drill

Hello, enjoyed you video, very informative. I wished you had included 18-8 stainless steel in the mix. Also, including cobalt cutters would be informative. Comparing M35 cobalt to M45 cobalt would be interesting. Thanks

Hey Project Farm, what's the best toilet paper? Project Farm: On the whole, they're all pretty good!

don't buy Milwaukee consumables, absolute garbage.

i would love to see a long video of the sheer quantity of tools you have collected over the years and the ones you use daily. thanks for helping me with all my tool purchasing decisions.

Don't know what brand they are (from McMaster) but I've had good luck with the cobalt cutters. Once you get a feel for it, they can last a long time.

In the UK we call these rotary cutters or mag-drill bits. I was surprised you didn't have any 'Rotorbroach' cutter's, as they are the pioneers of magnetic drills for metal working. Unibor also supply carbide tipped cutters. Jancy are the company behind 'Slugger', therefore they too are a branded cutter and should perform well. Thanks for your continued, concerted efforts.

So, some basic machine shop here. Cutting speed in surface feet per minute of spring steel is 10 to 25 feet per minute so using the maximum cutting speed, RPM= 4xCS/Diameter (of tool) so Rpm = 100/.9375 That rounds to 1000/.94 or 106 rpm . Those RPM values will only decrease as the work materials become harder. This test was conducted at speeds which were certain to destroy the tool.

Years ago, we used a "Hougen" unit. They supplied the motor and bits. Portable with a magnetic base. On high rise structural steel beams, it would cut through 1" steel beams with no problem.

If you keep the coolant flowing, the $3 annular cutters from China do a fine job. ..not sure why you’re paying 29?

Anybody know why a set of annular cutters comes in oddball sizes? Like 13/16, 15/16, 1-1/16 etc?

Where did you find the euro or cotter at $44? Amazon was much more

This was a really good test as i have a mag base and trying to select the best bang for the buck

Your speed is way too high for the steel test. Feed them, don't speed them. 400 rpm mild, 300 spring

Has anyone yet tried these in a lathe? Even with the slug standing, I guess this could be a game changer for large bores.

Recently got a magnetic drill which uses annular cutters. Looks like the Eurobore would be good replacements when I need some.

Thanks ....might want to had hole size as the tool wears on also.???.....great content as always.

Minor correction: though it is now widely used for making target plates, AR500 is designed to be abrasion resistant, for use as wear plates in heavy mining equipment. The name is an abbreviation of "Abrasion Resistant, 500 Brinell"

I'm behind in your video good sir I had not seem this one but I loved it

I picked up a (newly released?) tungsten carbide tipped set from Jestuous at $265 for 13 bits, the first thing I did was send a couple thru an old pitted AR500 target while they’re still inside the amazon return window, they ate into it just like the CTC’s show here and seem to be excellent so far. I’ve also had good results from the Jestuous 1/4 and 1/8 TC grinding/cutting burr bits.

Have you or will you do a Mag drill test? Thanks for the info and content.

Dude carbide can be fed up to twice as fast as HSS. . . Put a 30lbs weight on it and watch it rip.
Also, I'm a tool maker, I'd rather make my own carbide tipped cutters so I can make them to my accuracy standards and make them have a long resharpening life.

Please make a video about inverters
HehehehJhksndkwjsksjdjs wkejx hahahahahahahhaahhahaha woooowowowowowowowowowawawawawawwa😂
You make great videos

Carbide will appreciate a faster surface speed . Take the cutting speed of the material in surface feet a min x4 the. Divide by the diameter of the cutter will be the ideal rpm of the cutter. HSS spins less than half the speed and they need coolant to have cutting edges survive

once you fuck up the bit go have it sharpened, you messed the bits up from the get go, thats ok thou your not a iron worker

god damn man, dont force burr bits fuxk

your buring those up not using the right fulided too, lmfao

slow down your rpm man, damn

Thank you so much for your ongoing (and well done/ comprehensive) work!!!

There's a lesson to be learned here about Milwaukee drill bits & cutters

I use the Champion brand annular cutters almost daily at my job. most times with a mag drill. Most common thickness I drill is 3/4" or 1". they are amazing.

People don't realize how hard ar500 material is especially hardox brand

I learned about annular cutters 14 years ago when I was building a front bumper for my Jeep. I was amazed how quickly I drilled a one inch hole all the way through a quarter inch wall 2x2 steel hitch receiver!

Did you use the same cutter, from each manufacturer, for all of the tests? Or, did you use multiple or a new cutter for each test?

Im surprised nobody has added up how much you spent on how to show us the best brand. Thank you sir 🫡

I'd choose Euroboor all day long, for the price to achievement ratio. Thanks for all you do.

He makes me happy

You have to include some actual tool companies cutters. Chicago Latrobe, Norseman, Viking, GreenField, Cleveland. Champion was realistically the best in that group because there a real tooling company.

Does anyone else spend time watching this and then realize that you don't even own a garage

What Aluminium alloy did you use?

Have you tested tin snips?

You missed the best brand in annular cutters, Nitto-Khoki.
