When fabricating a large volume of pipe, would you ever use cutting fluid or wax? I was considering using some on a 1.25" hole saw but Im unsure if that could degrade the gasket on the grooved mech tee.
The manufacturers instructions that come with the Mech T’s say Do Not Lube so you would need to wipe clean the pipe . The heavier Mechanical T’s get lubed . Either way you need to wipe clean the hole . I prefer not to use the cutting fluid but if you want you can use it . I use a pilot clamp and the lube and shavings would just make a mess of the clamp . Personally I don’t think the lubricant is worth the effort .
Any particular type of hole saw you prefer? Bi Metal or Carbide Tipped? Any brand choice? I'm not using any cutting fluid either. Do you do anything extra to cool the hole saw? Also high speed and low torque or low speed high torque? I'm using a cordless 18v Milwaukee brushless
@papasmurf6058 I use Milwaukee drill. High speed . High torque . Faster and stronger the better on small size holes . I don’t want the drill to stop ! Bi Metal works good . No preference on hole saws I use whatever hole saw my company buys or suppliers stock .
Because 50 % of the time the coupon shoots down the pipe and becomes a pain to get out even with a magnet stuffed inside the pipe .If the pipe is being fabbed on the ground ok i will use pilot clamp without the pilot bit . When im drilling into an existing pipe in the air then i use the arbour with pilot bit .
What city do you work for Johnson Controls in? Some of the gear your using is a dead giveaway cause it’s the same as everything I have lol. Gloves, bump camp, high vis vest, and goggles.
I know what you mean ! Getting hot bits of metal on your skin isnt fun .You can drill out the threads on small strap t saddles with 1.25 in hole saw . But only good for small size pipe for 1 in outlet.
If you want to file and get wet then file away . If you don't damage the surface area where the rubber sits then I rarely use the file. This is service work and most times the water doesn't stop . If I notice lines or gouges then I use a floppy disc with a portable grinder . The benefits of using the pilot clamp is it leaves a clean surface . The saddle sits inside past the sharp edge of the pipe anyway. File to much and it removes the protective coating on the pipe that could cause problems years later. When I first started I was file crazy but got tired of losing or buying files.
Now just gotta undo it again to get that hangar out from under it 🤣
Lmao
😂

Okay thank you for the insights. I'll use setting 2 for high speed tomorrow since I'm drilling 1.25" holes for grooved mech tee 🙏
Jack the hanger up next time and you’ll get less water
What about the pump pressure? Water are going down is it balance or pressuris?
The water is not under pressure as i closed the valve and drained the water . The water you see is trapped water .
Can i ask why u still use a pilot bit when using a pilot clamp? I never do, it seems to me that its a waste of time and a waste of pilot bits

Nice. Glad to see your union. We’re union here in Pittsburgh to.
I have the same gear in NY 😅
You union in NY?
We're do you get that from that clamp that goes on pipe?
Its called a Pilot Clamp . Sprinkler wholesale might sell them . You can also google the name .
National Fire Pilot Clamp .
Comes in a yellow box .
@@SprinklerFitting thank you so much
Nice work! Would love to hear your thoughts on our tool - the Snapdrill.
Nice job and a great video!
Thanks I have watched a few of yours as well .
I wish i had that pilot bit. Ive had to drill about 100 of these using a dummy strap.

the hanger are very close to your sprinkler..
It is a pendant sprinkler in ceiling below. If it was an upright exposed sprinkler then nfpa 13 says minimum 3 inches away.
Amigo como se llama la herramienta que usas para centrar el agujero del taladro?
Amigo, se llama pinza piloto (Pilot Clamp)

@@SprinklerFitting Thanks friend, but I think it is not sold in Spain. If I get it, it is a good help.
Google pilot clamp and see what you can find . They are expensive .$750 cdn
@@joseluiseirasgonzalez8122 you don’t need to drill a pilot hole first you don’t even need a pilot bit. They break all the time.
Bad teaching,always file any hole.
If you want to file and get wet then file away . If you don't damage the surface area where the rubber sits then I rarely use the file.

@@SprinklerFitting i only file if its painted
I guess there is no need to get the burs filed off……
Not really ,hole saw cuts clean hole , if the area where the rubber sits has scratches or burrs then i would file ,
