4. Sharpening cutter teeth

Sharpening stump grinder teeth produces dust that is hazardous to people 
and animals. Do not sharpen teeth in the absence of a dust collection system 
and adequate ventilation. Cutting tools may shatter if they are misused. Be 
sure to use shields and eye protection when sharpening or in the vicinity of 
sharpening. 

Stump grinder teeth have a carbide tip that is silver soldered to a steel base. The carbide tip is what actually cuts 
the stump. The tip also shields the steel beneath it from being worn away. Maintaining the sharpness of the carbide 
and keeping down relief at10 degrees (see Dimension A, Figure 15) will result in a machine that cutsmore efficiently 
than a machine that has dull teeth.

To sharpen the tooth properly, you must use two different wheels  one wheel for the carbide and another for 
the steel. The procedure for sharpening teeth is as follows:

i. Use the steel grinding wheel to grind 
    away some of the steel that is beneath 
    the carbide tip. Grind steel at a 
    12 degree angle (see Dimension B, 
    Figure 15)

ii. Use the carbide wheel to grind the 
     carbide at a 10 degree angle
     (see Dimension A, Figure 15).

Grind until the carbide does not overlap 
with the steel and the top edge of the 
carbide is sharp.

iii. Teeth may be sharpened as long as 
      3/8 of carbide remains on the tip 
      (see Dimension C, Figure 15). 
      Replace any tooth that has less than 
      3/8 of carbide left.

Do not attempt to cool stump grinder tooth after grinding by immersing it in 
water. Immersing hot tooth in water may cause carbide to crack.
