Thick backs eliminate the need for driving plates and prevent drive pin holes from elongating. Less vibration for smoother cuts. Shatter resistant. Use with arbor appropriately sized for drill being used. Contains cobalt for wood and metal applications. Faster, more aggressive cutting with 4/6 tooth design, featuring varying tooth sets and deeper gullet for efficient chip clearance and less heat build-up to allow use with high-RPM portable drills.
