Bits and Shanks

[Daren12]

Need some help in trying to replace bits and shanks on a mobile Dimension 128 usually cut pine, spruce and hemlock.  Any advice on going with a smaller tooth 732.  I really enjoy this site as I get a lot of useful information and read it daily faithfully.  Thanking everyone in advance.     Correction it is 127 not 128

Hi Darren12 and welcome

Daren, do you mean finding the bits and shanks or actually the process of replacing them. If replacing you will need the special tool to twist the shanks out, and in, of the pockets Menominee saw (see left) should be able to help on both counts. If the old shanks are rusted/gunked in penetrating oil will help. Frank C.

I'm not sure what you mean by a smaller tooth.  I'm also not familiar with those numbers.  I worked with the standard bits and shanks in the mill business.  A saw is made for a certain style of shank.  You won't be able to go to another style and keep the same blade.  You can get teeth that aren't as wide, but you don't really gain anything.  Your side clearance is less, and that can cause some heating problems in the saw.

Seems to me, if you're thinking of going smaller, you're having some sort of problem or you think you'll get a gain in output volume.  You might get a bit of a gain, but you might also gain more headaches than what it's worth.
