Impaktor Bit - Phillips #3x25mm - excellent long lasting bit for use in corded or
cordless impact drivers with 1/4' bit holders. Black oxide finish
with diamond coated tip to maximize grip with the fastener and
prevent cam-out. Best if used with Wera's tri-torsion bit holder.
See Wera's press release on this new series of impact bits. These
are arguably the best impact bits on the market today.
