"Excellent quality from erbauer in a case that's almost too nice just for drill bits.
They do however require a pretty powerful drill to pull through the wood as my smaller drill won't even entertain them. Large drive size also so check before buying your drill will cope with them. Very good set though."
"Excellent value for money, do the job very well, wear rate is also good, even with intensive use they stay sharp longer than other augers of this type. Now on our standard supplies list. If you need holes this size these are the ones to do it."
