  TAPERED 6 FLUTE 7 DEGREE REAMER  adjustable T handle for added torque or compact storage  USED TO TRUE OR RE-MACHINE & DEBURR EDGES OF HOLES IN WOOD OR METAL FROM LUTHIER WORK TO MACHINIST & PLUMBING  tapers from 5/8 to 3/16" DIAMETER I have had several people ask what the taper is in degrees. this can be figured out using a bit of high school math/algebra and geometry: assuming the full length of the reamer was 4" (its slightly short, however not to a point either) the diameter = 25.132". dividing the 5/8 into the circumference would yield the ratio of the diameter to the circle (.025) , when applying this ratio to 360? you would get 8.925 total degrees, half of that per side is approximately 4.46? it can also be determined using the gauge in the last photo shown.
