Very true, this will work and should work well. Tho' for the first few
mins it will be a little slow until the teeth wear down a little, you
can get a round this be taking their points off on a grinding wheel.

     In recent posts,the use of banding or plumbing strap is a staple
for 
the ATM.The trepan cutters I make all have notches  cut into their 
rims,thus allowing for the tool to capture the grit.May I venture
another 
material that can be had.
    Ever think about using the bi-metal blades off a band saw.If you go
to 
a welding shop, ask for have one of their used band saw blades.These are

about 1" wide,and will probably produce a 1/16" kerf.Most blades are
softer 
at the back edge so they can easily bend around the driving wheels,and
acts 
as a shock absorber.You can punch a series of holes in this material.The

teeth will capture the grit accelerating the cut,(in theory at 
least).Though some of the teeth may be gone,it shouldn't effect 
performance.It's worth a try and it should cost nothing to do.
regards,Ron
