Description
Trust Ideal step drill bits for precise, repetitive drilling through the toughest materials including brass, carbon steel, cast iron, stainless steel and more. These tough and reliable tools are constructed with a rugged titanium nitrite exterior coating. Each step is gradually blended to ease stepping throuhg hole sizes; reducing the need to keep changing drill bits, which speeds up the fabrication process. Improved Split-Point tip design eliminates the need for a starter hole or punch and delivers three times faster starts, saving valuable time. The double fluted design provides balanced cuts and cooler operation.

Features:
  • Durable blow-molded case securely holds and protects bits
  • Kit includes four step bits (35-511, 35-513, 35-515, and 35-517)
  • Kit provides a solution for every electrical hole size between 1/8 in. and 1-3/8 in.
