Band Saw Blade Tooth Recommendation

FROM A NEW CUSTOMER:
"Hi. I fabricate custom Jet Ski stands out of 2" square tubing, angle & 2-1/2" angle, wall thickness varies between 1/8" - 3/16". I own the Grizzly G4030 metal bandsaw ( http://www.grizzly.com/products/6-1-2-x-9-1-2-Metal-Cutting-Bandsaw/G4030 ) It does the job fine. I do however need to purchase a great metal blade for my application & I'm hoping you can point me in the right direction. The blade size is 85"x3/4, still unclear regarding the best need of TPI, hoping you can point me in the right direction. I look forward to hearing from you & hopefully purchasing some quality metal band saw blades. Thanks, Carl Petron www.tufstands.com"

I DECIDED THAT THE A 3/4" BIMETAL M42 BAND SAW BLADE WITH A 10/14 TOOTH PATTERN WOULD WORK OUT GREAT FOR CARL. WE DISCUSSED HIS OPERATION ON THE PHONE AND VIA EMAIL.

"Joe, I appreciate your follow up call earlier today, this tells me where I'll be taking my business from here on in. Basically I own the grizzly G4030 metal bandsaw (http://www.grizzly.com/products/6-1-2-x-9-1-2-Metal-Cutting-Bandsaw/G4030 ). It's a simple bandsaw that does the job for the application I am fabricating. As per your recommendations the Bi Metal M42 (10-14 TPI) 3/4" WIDE is the best blade for my needs. I spoke to you about length and I'll require a 85" length (see Grizzly link specs). I look forward to hearing from you. I plane on purchasing well over $100 in blades & take advantage of the free shipping. Thank you sir. Carl Petron"

Cutting bundles of A615 steel-small round bars

Today I helped a customer cutting A615 rebar steel. They had 49 pieces of 1-1/4” solid round bars bundled together. We needed to help them get the fastest cutting time they could, for their production requirements are very high!
Whenever I cut small round bars in a big bundle, I know we are going to have issues stripping out the teeth on the saw blade if were not careful. Since the steel from the mill is never EXACTLY 1-1/4”, or whatever size you have ordered, the possibilities of your bars spinning during the cut are common. When the bar spins, you lose teeth on the blade-regardless of the manufacturer of the blade. To help combat this, we welded the ends of the bar together, clamped the material as tightly as we could using the band saws top and side clamps, and used wood wedges in the event a bar became loose during the cut. We tried a number of different speeds and feeds to try and find the sweet spot for his production requirements as well as trying to give him the best blade life I could. As you know, faster cuts mean less blade life. It’s a balancing act when you need both. We were able to cut his bundle of 49 pieces with 60 total square inches of material cutting at 8 minutes beautifully. We were cutting faster (around 6:30 per cut), but I felt that the increased speed and feed rate in doing that might create an opportunity for more of those spinners I spoke of earlier. As of this minute, the blade has been cutting for 2.5 days and is still going strong!

Cutting tubing in Georgia

I had a really interesting phone call today from Georgia. This gentleman was looking for a band saw to cut angle iron and structural tubing. He needed to have the capabilities to mitre cut, and a saw that would last for years to come. Together we decided that we were going to solve his needs with a Hyd-Mech S20 band saw. This saw is built so much better than most other saws in its class-I know he is going to have great results. We included 6 bi-metal band saw blades as well as a 5 gallon pail of Sawzit 2000 semi-synthetic cutting fluid with the purchase.
He also needed 20’ of roller conveyor to support the material he planned on cutting. His budget really didn’t allow for that though. Our solution was to sell him the actual rollers that go on a roller conveyor, and with his new saw he was going to fabricate the legs and support stands he needed to build the roller table himself! With his new saw he just saved himself nearly $2,000 by using it to fulfill one of his immediate needs. Very cool!
