Drill America Cobalt 5-Piece Set
This Drill America cobalt drill bit set contains five reduced-shank bits sized from 9/16 inch to 1 inch. It is intended for machinists and fabricators who need to enlarge holes in hard steel or stainless alloys. The cobalt blend resists heat buildup during extended drilling cycles. Buyers who need smaller pilot bits or metric sizes will not find them in this package.
Reduced Shank Build and Case
Each bit has a 1/2 inch reduced shank that fits standard drill chucks without a sleeve adapter. The cobalt steel body maintains hardness at elevated temperatures while the shorter shank keeps the overall length manageable in tight work areas. A transparent plastic case holds the bits securely and lets you confirm the size at a glance. Users with 3/8 inch chucks cannot mount these bits directly.
California Proposition 65 Notice
The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. No extra accessories, lubricants or software are bundled with the set. The warning informs professional users to follow standard shop hygiene such as wearing gloves and washing hands after handling. Buyers seeking a kit with cutting fluid or a drill index must source those separately.

Questions about this item
What shank size do the bits in this Drill America POUDWDCO set use to fit a standard drill chuck?
Each bit has a 1/2 inch reduced shank so the five large-diameter bits can be held in a common 1/2 inch capacity chuck.
What are the exact drill-bit diameters supplied in the five-piece set?
The set contains 9/16 inch, 5/8 inch, 3/4 inch, 7/8 inch and 1 inch cobalt bits.
Does the cobalt material require any special break-in or lubrication step that users often skip?
Use cutting fluid or oil from the first hole; running the bits dry on hard steel is the most common mistake that burns the cutting edges.
