HIGH SPEED STEEL PRECISION RISER SLOTTING / COPPER SLITTING SAWS / (JOYAL®)
Used for slotting copper commutator risers and other materials that produce long, stringy chips.

     The two styles of  saws shown are for Commutator Riser Slotting.
     These saws are precision ground on all surfaces; dimensions are shown above the illustrations at right.  Formed teeth are on center, with a 15
° back-off and 45° alternate bevel which is 1/3 the width of the tooth. Saws are hollow-ground to provide clearance between the periphery and the hole. 
    
*Saws are stocked in thicknesses from 0.010" through 0.069" in 0.001" increments.
 
Thickness tolerances are +.0000" -.0002"

Alternately beveled teeth
(see sketch) produce chips of less than the width of the slot being cut, eliminating the tendency of the chips to clog.

For prices of thickness not shown, use next higher price in schedule (plus a slight grinding charge for smaller quantities).  Other diameters, hole sizes, thickness, number of teeth, also available on application.
