Run them with liquid coolant, hold the weight on them and do not back off. Now try a decent quality cutter and see the difference. Also get the correct holder for them with the spring loaded centre pin and internal coolant supply. Drilled tens of thousands of holes with these cutters and without the correct set up you will burn through the cutters rather quickly.
I recently built my own 5/8 fixture table and the 5/8 Vevor annular cutter did over 400 holes without giving up using the Vevor mag drill which i did not expect to survive but it did. great product for the money. Great review Stan.
For the scale I work on these are interesting for trepanning lathe jobs so I can get a possibly useful drop out of it. Thank you for the look at the them.
I use annular cutters a lot at work and in my home shop. Anything under 25mm I run at 700 RPM, always use flood coolant and good steady pressure. On deeper holes to manage the swarf I break pressure but don't retract the cutter. A few tasks I have found to be perfect for annular cutters you might not have thought of: notching pipe/tube (takes practice), creating round mounting posts or Stan doffs then mill away the surrounding material, trepanning in the lathe. This can also be used to core material and cut down on waste. For example, making copper washers this way leaves an internal bar that can be used for something else. Great vid as usual 🙂
A nice review Stan. I'm very impressed with those annular cutters. Vevor stuff isn't half bad for the money. I recently bought a Vevor 125 mm (5") three jaw concentric chuck and for £42 GBP ($50 US) the accuracy wasn't too bad ( about .002"-.005". ) I had to make a backplate so I went to the trouble of making it adjustable so now I can dial it in to within half a thou.
Just used 4x vevor load skates and 10t toe jack to move a 4tonne hydraulic pan brake. Can't complain with the quality for the price. Got it moved across my workshop floor by hand.
One note to add about the center pins / mag drills. When the pins retract, they also allow coolant to flow through. So if you’re using a coolant tank, you don’t have to come out and relube.
Annular cutters are great for misc work, they really excel for structural steel work as that is the intended purpose. I have drilled over a thousand holes with a Jancy Mag drill and annular cutters. The best way I found to use them is to load up the inside of the bit with cutting fluid and once the cut engages never retract the bit. Just keep the coolant at the cutting surface and use a chip brush to clear away the nest. The only time I have ever seen annular cutters break is during a re-engagement (starting-stopping-starting) the cut, and the occasional user who tries to push the bit through the steel opposed to letting it cut. They do not respond well to unbalanced cutting, the beginning of a cut where one side is engaged and the other side isn't. Cutting between adjoining flanges for example. If the cutter breaks a tooth or fails as long as there is a solid piece to work with they can be re-sharpened. HSS cutters for the majority of the work, carbide tipped for MIG welds or other expected hard materials.
The "slugs" are great to keep around for welding or plugging holes, I welded a lot of slugs in the end of tube for handrails. If a hole is accidentally drilled in the wrong place, weld a slug in and recut the hole.
I have the same set and did a review also….annular cutters are feed non-stop (hence oil/coolant)….peck drilling is not the correct use……NICE review, you can purchase an R8 holder that uses the pin
Anular cutters are definately continuos cut tools.. yes it birdnests.. butthey are intended for it. The slot on the pin is for through center flood coolant to help evac smaller chips.
Thank you for your comments on something being "perfect" - it just doesn't happen. Yours is about the 3rd video I've seen on these Vevor Annular cutters and I'm finally convinced they would made a good addition to the Tin Barn.
I use annular cutters on my mill and lathe. The arbors are more complex inside than you would think. I really recommend just biting the bullet and buying a decent arbor. If you drill stainless, I also recommend carbide cutters. It’s really easy to destroy these cutters on stainless. You would have to go at a really slow speed given these are not small diameters, that speed could be at the very bottom speed of a mag drill. We’re talking at below 200 rpm. So, carbide is much better. I’ve found that some of the most expensive hss bits from Fein Slugger are not much better than some other cheaper bits. Never used the Vevor bits.
The arbor is not very expensive, of course made in China, with a tail for Bridgeport or Morse. It is available an arbor with an attachment for cooling which will extend the life of the cutter.
I've had the same experience as @mangajack. 1020 holes through 1" plate without sharpening. Any cutting oil works but don't peck. A chip gets in the slot and jams and chips your cutting edge or complete cutter broken. Yep, birds nest horrible but just keep drilling. Only take half the time and your hole size will probably also be better.
Absolutely, "pecking" with annular cutters seems to be when they get damaged. Plenty of lube- tapping paste is good- and gentle hand feed and they'll fly through. Peck and you stand a chance of chipping the teeth for some reason.
Nice review, Stan. The oil seemed to make a cleaner slug, but cut hole looks the same. I prefer Anchorlube, even having to stop and reapply, due to less mess to clean up since it says in place, rather than running and dripping everywhere. Cheers, Gary
I've had the opposite experiance. Anchorlube tends to run and slop everywhere once it gets hot. Coconut oil seems to work the best for me out of all the affordable options.
Looks like the 2" cutter is pretty beat up from a single hole. I blame it on pecking, never peck - it just destroys drills. If you need to break a chip, just relax the pressure.

Those annular cutterd are fantastic Stan. That's an amazing angle plate you're building. Hope to see the finished job. Cheers Nobby

You can also get R8 and Morse shank arbors to hold them. I use them quite often on my lathe in the tailstock. As well as in my BP mill.
Nice review Stan, They worked great for the purpose.

Nice concise review Stan! They seem decent & priced right!. Thanks!
Nice review Stan. Well done and one more great Bash.
Outstanding work. 👏👏

If you use a water soluble solvent and keep it wet all the time they tend to cut better and last longer.
great stuff, thanks

this is lovely
If VEVOR ever wants to send me ANY of their tools or machines I would gladly make review videos of them and post them to every social media app! 😊
Didn't know John Goodman is a machinist! lol... great review.
Nice review thanks for sharing
I wonder if the tooth burn is from cutting through the mill scale at the start.
What’s the brand of the left-handed digital calipers?
Looks like the 2" cutter is pretty beat up from a single hole.
I blame it on pecking, never peck - it just destroys drills. If you need to break a chip, just relax the pressure.
Perfect……Strive for it ( when possible) but know it’s unobtainable
Thanks for the review.
As a hobbyist seems like the way to go
Thank you Stan for sharing. Especially this week i'm sure you're very busy looking forward to meeting you .Kimber
wasnt expecting the barz productions lol
I guess I need to increase my rpm. I've run 1.5" Chinese annular cutters at only 70-100rpm
Go carbide tipped they works wonder...
Shanghai VEVOR Machinery Equipment Co.,Ltd
You should NEVER wear gloves around rotating equipment. I know someone who wrecked all the tendons in his hand because he wore gloves around a mill.
Someone linked info on Vevor stealing IP... Now gone. Tons of lawsuit against Vevor, very very bad company,
No such thing as IP.
FIRST...great video Stan!

Why the fu*k are so many youtubers shilling vevor lately!?
