Lennox one tooth bits – self feeding?

Just curious these look great. Is there any “self feed” action or is it gravity and elbow grease? (I see they don’t actually take much effort but if drilling over head etc….)
Thanks
John

the single cutter ship auger is self feed...
it works...
fast too....

I am referring to the single tooth hole saws, not ship augers.
Do they self feed or do you have to push them through?
Thanks

the self feed would come from the pilot bit, no?
so I would have to say that they do not self feed, but I'm sure they are easier to control, as they work kind of like a saw blade that limits how fast you can feed them into the stock....
I wish I didn't know now, what I didn't know then
Gives me a great idea. Replace the drill bit with a 1/4" lag or timber screw. I'll call it the "Armbuster".Spheramid Enterprises Architectural Woodworks

I'll buy one.
I modified a Greenlee or Mil. Selffeed 1.5" forstner type bit so it could follow a 1/2" dia. bolt hole in logs. Needed to make a hole for washers and springs to attach log treads on stairs.
The screw point was held in by a set screw, like a pilot on a hole saw, fine and coarse threads for feed speed. I turned a threadless pilot out of rod stock to a 1/2" dia, and necked it down to fit the old auger points hole and filed a flat for the set screw.
I could drill my half inch hole first then, and make the larger hole concentric and alined with the first, just by using it as a guide.
Because of the nature of the assembly, I had to work kinda backwards from the normal "drill the big countersink first, then follow it's center" that is mostly used.
I just bought two smaller Lennox HS, for making custom washers, a 3/4" and a 7/8''..I recently had my trunnion on my Table saw lose it's E clip that the blade raiser worm is held in place with, swallowed up in the dust collector. I bought new E clips but was missing a REALLY thin thrust washer, I wound up making one out of Teflon, lacking any spring steel that thin. It had to have a 5/8th ID , and I had a step bit for that, but no plug cutter or HS for the OD, like 13/16th..now I do.
Just for a test, maybe I'll add a screwfeed to a small HS and see what kinda pitch it needs to feed in softwood or hardwood. Right after I make a 5/8th OD washer to adapt a sawblade to my weedwhacker.Spheramid Enterprises Architectural Woodworks

They are like any hole saw, you push them through. The one big tooth cuts faster than the small finer typical hole saw teeth. Makes a ugly hole real fast.
do the Milwaukie self feed bits (not ship auger) make cleaner holes?
Thanks
John
Yes they do. At least the old ones I have do. I hear they are now made in china and do not have the same quality as in days of old.

The true "self-feed" have a replaceable tip with threads to pull the bit through wood - at least until you hit a nail. Not as neat a hole as with a ship auger type but less power is needed to drive it. Makes quite a mess though so I only use these in the shop. Recently tried out some of Hole Pro's new Blue Boar brand "self-feed" and universal multipurpose hole cutters on a variety of materials at a job site. Cut through wood in a flash but also Hardie cement board, Wonderboard, OSB, stucco, and sheetrock. The gullets are important with any hole cutter with a barrel that holds a cut plug. The wider and deeper the gullets the easier it is to remove the plug and get on to the next hole. This is especially true when you have two materials to cut through like stucco or cement board over OSB where you end up with two plug segments. We needed to cut some soffit holes for recessed lighting in Hardie board and the electrician tried using a bi-metal hole saw. After the third hole it was toast. The next day I brought a Blue Boar stucco bit and he finished the job in no time at all and kept his part of the project on schedule. The Blue Boar were the easiest hole cutters I have ever used in terms of both cutting fast and getting the plug out quickly. I tried a new Lenox hole saw later in the week and was amazed at how long it took to cut through a piece of fir. I will never go back to using hole saws again.

I just tried the Milwaukee 3 tooth version. It made a hole similar to what a shotgun would in wood - quick, but rough as heck!

Look, just send me to my drawer. This whole talking-to-you thing is like double punishment.
I had a custom 2 3/8" single tooth carbide hole saw for about 2 years. this was a couple years back before lennox ever came out with theirs. we used it to cut grommets in the tops of desks. worked like butter the whole time. was not "self " feed, and the lennox looks the same.
BUT, cut through with the minimal effort. worked great till it met that screw. double/ triple check the cut. have not tried lennox because I haven't seen that they maqke a 2 3/8". now use a "forstner" style attacthed to a rubbermaid/weatherstipped sheid attached to a rigid shop vac. not super fast, but really clean.
