USA-made mechanic length drill bit set designed for metal, steel, stainless steel, sheet metal, cast iron, brass, copper, acrylic, and general shop drilling applications. The Trident stepped point design starts fast, stays centered, and reduces walking for improved hole accuracy and control.

The aggressive Trident stepped point geometry starts quickly, stays centered, and reduces walking on curved, hardened, or difficult surfaces. The unique point design also makes enlarging existing holes easier without damaging the cutting edges.

Mechanic length construction increases rigidity and reduces flex, while the black and gold finish improves heat resistance and durability. 3-flat shanks help reduce chuck slippage during drilling.

Packed in a durable steel index and built for fabrication shops, automotive work, maintenance, production, and industrial use.

 Recommended for Cast Iron, Brass, Sheet Metal, Acrylic, Mild Steel, Copper, Hard Steel.
