Are all anchors set with A.N.S.I bits and why?
A.N.S.I. stands for American National Standards Institute. This organization exists to set national standards so that you can be assured of consistent dimensional reliability from manufacturer to manufacturer. Most anchors are tested using bits made to these standards and you as an end user will want to stay within the standards’ dimensional limits to insure that you will achieve the performance you are expecting from your anchor. Nearly all anchor manufacturers recommend the use of A.N.S.I. B94 Standard for carbide tipped drill bits. Metric drill bits generally do not fall within the dimensions set in A.N.S.I. B94 for carbide drill bits.
