Put on some safety glasses so you can get really close up to it, use both hands, and run the dremel at a medium rpm so not to get the blade too hot. You will be able to get a few more cuts out of a dull blade but no matter how steady you are, the tooth geometry will change from tooth to tooth. Snip….My comment is directed at the premise of the post: That sharpening by hand will yield a sharp blade.

How many times can you sharpen a bandsaw mill blade?
You should be able to sharpen your blade two or three times before needing to replace it, but sometimes breakage happens. Blade breakage can result from a range of situations. Common causes of blade breakage include: Dull teeth.
How long do portable sawmill blades last?
Some can last under six months, and some can last years! Some of the most important variables to consider are what you are cutting, the condition of the machine and blade, how long you are using the blade, and even how you are feeding the wood through your saw as well.
How often do you have to change blade on a sawmill?

How long should a sawmill blade last?
On average your bandsaw blade should last 6 months to as long as a few years depending on what your cutting with it. Make sure to match your blade strength and quality to the project and material your cutting.
Are saw blades worth sharpening?
When your circular saw blade becomes dull, not only will it give you a rougher finish, but your saw’s motor will have to work harder and may burn out sooner. Sharpening your saw blades will save you money in the long run because you’ll get better cuts, and you’ll have to replace your saw and blades less often.
How do you grind a bandsaw blade?
Touch it against the teeth as you move the band saw backward by hand. As the blade moves, any protruding teeth will come into contact with the stone and sharpen down. Using a Dremel tool turned on at a low speed or a file, run the device at a slight angle from the top of the tip to sharpen the tip’s back.
How tight should a blade be on a bandsaw mill?
For carbon steel toothed blades (cutting blades) this is typically 15,000 to 25,000 PSI. Slitting type blades typically are tensioned in the range of 12,000 to 20,000 PSI. In general bandsaw blades are never tensioned past 35,000 psi.
Why are my sawmill blades breaking?
It is essential that the rollers are in good condition without any traces of wear, such as deformation (cone shape), damaged bearings, worn-out roller flange. Worn rollers cause the sawblade vibration and unstable work in the wood, which will lead eventually to a breakage. If the rollers are worn out, replace them.
