About This Product
Alright, if you do any kind of serious metal drilling—especially deep holes in steel, iron, or tough alloys—you need good bits.
This MAX-CRAFT set gives you a bunch of cobalt high-speed steel drill bits in both 6-inch and 12-inch lengths.
Cobalt is the way to go for hard metals; it stays sharp longer and handles heat better than standard HSS.
The set includes ten bits ranging from 1/8 inch up to 1/2 inch in diameter.
They’ve got that characteristic cobalt ember finish.
Part number is AC01080102-6L12L.
These are perfect for aircraft work, automotive, fabrication, or any time you need to drill deep and straight.
They’re brand new, still in the packaging.
Whether you’re a professional machinist or a serious DIYer, having a set of good cobalt extension bits in your toolbox means you’re ready for tough jobs.
Don’t wreck cheap bits on hard metal—get the right tool for the job.
