How fast can I cut tempered masonite?

[knight_toolworks]

I need to bid on a very large job cutting what I hope will be 1/8" tempered masonite. I need to cut it fast to keep the price down and to be able get it done.
I was thinking a 2f downcut 1/4" bit the cut needs to be clean so I don't have to sand. we are talking 6000 pieces here. they are pretty big 24x15 with a simple handle cutout so they should vacuum well.

Sounds like the backing for roof shingle displays is back doing the rounds.
Be careful if it is, that one has been around the small cnc shops and suckered a few over the last couple of years.

yes that's it. this is a small ad company that wants to job. I know it would be a hello f a lot of work that if the orders get larger I would not do.
tell me what you know about it.

Steve, you can contact me off line, email or call & I will outline.

Your best bet is to get a sheet or two and make some test cuts, you can't afford to make a mistake on a job that big. Be sure to allow for the time it will take to handle 500 sheets of material - do you have a forklift?

It's not easy to get a perfect cut on 1/8" masonite.

the roofing manufacture is huge. so I doubt they would screw me. but a marketing/ad firm can. I was talking to my printing friend and he said may times the ad firm gets paid but people under them can get screwed.
I can use a forklift to get the materials close to my door.
Masonite does not cut well. but tempered Masonite does.
I did a test cut and 6ips was not a problem it cut really well and clean.
now how many bits will I go through? I have no idea cut time for each sheet is 5 minutes. I guesstimated 12 sheets so I will be doing pretty well.

Use coated bits. Get a 50% deposit on the work before you begin. Get the 50% balance upon pickup/delivery.

Plus they buy the material and bits up front and a contract I think.
what kind of coated bits ? I emailed centurion to see if I can get a price deal on short 1/4" bits.

If it is the same thing, i have cut 1/4 masonite and i have found it stinks a little bit, but also and this may be realted to my feeds/speeds but the edges of the cuts tend to feather out a little but i take a piece of sandpaper and a few swipes back and forth and it falls off and it looks great and cuts nice.

Titanium Nitride (TiN) or Titanium Carbonitride (TiCN ) Coatings are fairly common. They have a greater hardness and lower coefficient of friction than plain carbide & they only cost about a $1 to $3 more than a bare carbide bit - yet they last much longer. Most of the smaller mom & pop bit cutters won't have coatings freely available - most have to send them out. I buy coated bits whenever possible since they are superior to uncoated and only a buck or two more.
