The manufacturer states that this set is 8% cobalt, which would make this set grade M42. In the previous question the manufacturer states that this set is M35, which has only 5% cobalt.

Sorry in advance if this is a dumb question. new diy'er. will these be ok and fit chuck of a dewalt hammer drill? thank you!!

Yes they'll fit any drill chick the only thing they do not fit impact drivers those require a hex shank they will fit but never use the hammer setting with thest bits it'll ruin them

i have a lowes trailer made of thin angle iron having trouble drilling 1/4 inch holes what type bits do i need

These cobalt bits should work fine for that.
