585-3018002 - 29-Piece Industrial Black & Gold Drill Bit Set with Index Case

Reliable Drilling for Fabrication and Repair

For welders and fabricators, a reliable set of drill bits is as essential as a good torch. The 29-Piece Black and Gold Metal Twist Drill Set is built to handle the varied tasks found in welding shops, from drilling out spot welds to preparing pilot holes for bolted connections. The "Black and Gold" designation refers to the specialized oxide surface treatment that helps these bits stand up to heat and wear. When you are drilling through structural steel or preparing a bracket, heat is the enemy; this coating helps dissipate that heat and keeps the cutting edge sharper for longer, reducing the frequency of sharpening or replacement.

No-Slip Performance

Nothing slows down a fabrication job like a drill bit spinning in the chuck just as you apply pressure. This set addresses that frustration directly. Starting at 11/64", every bit features flatted shanks that lock securely into your hand drill or drill press chuck. This ensures that all the power from your tool is transferred to the cut. Additionally, if your portable drill only has a 3/8" chuck, you aren't limited to small holes. The larger bits in this set (up to 1/2") have reduced shanks, allowing you to drill larger holes without upgrading your power tool. This feature is invaluable for field repairs where equipment options may be limited.

Job Site Ready Case

Welding environments are tough on tools, and plastic cases often crack after a single drop. This set comes in a heavy-duty case protected by a rubber over-mold, providing the shock absorption needed to survive drops from workbenches or carts. The case isn't just tough; it's smart. It opens to display all sizes clearly, from 1/16" to 1/2" in 1/64" increments, so you never have to guess which bit you are grabbing. The removable cartridges are a favorite feature for mobile welders, letting you grab a strip of bits to take up a ladder or into a tight space, leaving the bulk of the set safe in your toolbox.
