A method for drilling out of a wellbore a first downhole tool located above a second downhole tool, comprising the steps of:

• providing at least one gripping member disposed on the first downhole tool;
• drilling through the first downhole tool until at least a portion of the first downhole tool falls down the wellbore or is pushed down the wellbore by the drill, thus engaging the second downhole tool;
• and
• drilling through the portion of the first downhole tool engaging the second downhole tool;
• whereby the at least one gripping member prevents the portion of the first downhole tool that engages the second downhole tool from spinning relative thereto when the portion of the first downhole tool is engaged by the drill.

A downhole tool for use in a wellbore comprising:

• a mandrel;
• slip means disposed on the mandrel for engaging the wellbore when the downhole tool is placed in a set position;
• and
• gripping means disposed on the downhole tool;
• wherein the downhole tool is comprised of a drillable material and wherein the gripping means prevents any portion of the downhole tool that falls downwardly in the wellbore, thereby engaging a downhole apparatus positioned in the wellbore below the downhole tool, from spinning relative thereto when the portion of the downhole tool is engaged by a drill to drill the downhole tool out of the wellbore.
