#1. Heavy Even Wear On Tips and Corners Of Teeth

Probable Cause :

Improper break-in procedure.

Excessive band speed for the type of material being

cut. This generates a high tooth tip temperature

resulting in accelerated tooth wear.

Low feed rate causes teeth to rub instead of

penetrate. This is most common on work

hardened materials such as stainless and toolsteels.

Hard materials being cut such as "Flame Cut Edge"

or abrasive materials such as " Fiber Reinforced

Composites".

Insufficient sawing fluid due to inadequate supply,

improper ratio, and/or improper application
