Klein Tools 53000 Regular-Point Drill-Bit Set, 29-Piece

These are standard jobber-length, high-speed steel twist bits with regular points, so they run in any 3-jaw chuck on a cordless or corded drill as well as in a drill press. They are round-shank bits, not hex or impact-rated shanks, so a 1/4 inch quick-change impact driver will not hold them.

General-purpose high-speed steel with a black-oxide finish, so they drill mild steel, aluminum, wood and plastics. The black oxide reduces chip welding when you're cutting metal, and the lightly roughened flute surface helps chips clear instead of packing in the hole. For masonry or concrete anchors you need carbide-tipped masonry bits instead, which these are not.

The hinged metal case measures 7.25 by 4.25 by 1.75 inches and the whole set weighs 3.25 lbs, so it drops into a tool bag or a van drawer without taking a shelf. Inside, three stand-up bit holders keep the sizes in order so you can see at a glance which one is missing.

29 bits, supplied in a hinged metal box with three stand-up holders. The box is part of the set, not a separate purchase. The part number to order is Klein Tools 53000.

No. Klein's own instructions for the 53000 set say never use the bits on or near live electrical circuits. These are plain steel bits with no insulation. De-energize and verify dead before drilling, wear approved eye protection, and follow the safety instructions in your drill's manual.

The 53000 is a regular-point set, the conventional 118-degree twist-bit geometry. It is the general-purpose choice for wood, plastic and mild steel, and it is what most pilot-hole and device-box work calls for. A split-point bit self-centers and resists walking on hard metal or a sloped surface, so if you're starting holes in steel strut or plate without a center punch, that's the geometry to reach for instead.

Yes, the 29-piece regular-point set is made in the USA, which matters on jobs carrying domestic-sourcing requirements for tools and materials.
