Topic tags/keywords: bandsaw blades

I seem to go through an awfully lot ob blades on my Jet 14” bandsaw. I normally use 1/4 inch blaedes because we do a lot of contour cutting (LOML uses it much more than I do). Actual running time is probably in the neighborhood of 3 or 4 hours a week.

Blades seem to last about a month or so, and break usually away from the weld. I’ve been using blades from Woodcraft Bands, which I think are by Lennox. The Olson Pro and Morse blades I’ve tried haven’t lasted any longer. I occasionally use a 3/8 or 1/2 inch blade, but never leave them on long enough to have any feel for how long they might last.

Is this degree of breakage normal? Anybody have any sugeestions to slow down my blade consumption?

I was having poor performance with my blades and someone suggested I speak with the guy’s at Suffolk Machinery (MFG’s of TimberWolf blades). They took about 20 minutes or so with me talking about what I cut, how I cut, etc… then made a couple of recommendations and I have not looked back since. You might wish to give them a call; I found it to be time well spent.

I reviewed their one of their blades earlier in the year.

BTW, I too have a jet 14”.

I second Chris’s take on the Timberwolf blades. They are of high quality and the folds at Suffolk Machinery
will talk with as long as you wish. Also, I would reccomend you send off for one of their blade
catalogs as it gives great instructions oh how to properly tension a bandsaw blade. I have a Rikon
14” bandsaw and it works great with the Tiimberwolf blades (I have 3’1 6”, 1/2”, and 3/4”)

if your doing alot of contour cuts, there is a possibility that your putting too much pressure on the blades when your cutting the turns. i used to have this problem cutting out spoons. I started making reliefe cuts which took alot of pressure of the blades and haven’t had near the problems since.

You may want to try SuperCuts Bandsaw company. They are on the west coast and their website is They make a premium blade that is unbelievable and they stand behind their blades. Cutting with one of their top quality blades is like cutting butter with a hot knife. It’s a small family owned company and they will answer all your questions. 1-800-356-9918

Other than using their blades I have no affiliation with this company.

Lennox makes good blade stock. If the blades are breaking away from the weld, it’s not the vendor who sold it to you, as the weld is all they are responsible for.

They should not break so frequently. I would suspect that something is putting stress on the blade in a way that should not happen. Perhaps it is cutting technique – pushing sideways or twisting. Or it could be a misalignment of guide or thrust bearings. If you back off the thrust bearing and guide blocks (both above and below the table) and run the blade, is it stable? Then bring the bearings back close to the blade without moving it forward, back or sideways.

If the thrust bearing had been too far forward, it could cause much more stress on the blade as you cut than a properly set thrust bearing.

You as a experienced saw operator, If your saw blades cuts good prior to its breakage then most likely as in many band blades a common condition of micro cracking caused by a manufacturing process can be found. If you are breaking bands away from the band weld (not the weld itself) then your problem can be found by examining along the sides of the band at the very bottom of the saw tooth gullets. Using your naked eye or in my case a 4X magnification lens, you will notice very-very small hair line metal cracks prolongation downward from the bottoms of the tooth gullet. Using a bright light source reflected along the side of the band you would notice several hair line cracks over the length of the band. Or in severe conditions a small crack in every tooth gullet, but you will notice that there is usually no more than one crack per gullet. A thin layer of de-carbonation of carbon steel occurs during manufacturing causes this condition of micro cracking. Carbon itself is a very brittle material, slowly over usage and time this results with the de-carb layer or also called white layering, cracks at the surface of the substrate and slowly the crack will expand. This is why as long as the band is still sharp and cutting well the band blades will break suddenly during the same or similar cutting process. Let me stress this is a manufacturing process failure and it can vary from blade to blade and style of blades even from the same manufacturer. So one size and TPI blade can cut very well on your saw and a different blade results in failure. Only if you need and use a band manufacture with a controlled manufacturing process for every style manufactured is a blessing. Other than that finding a manufacture that makes the band you need to perform will do. Additional stress caused by other issue like bearings and band tension will expedite this failure condition.
