Irwin Hanson 90170 High Speed Steel Drill Bit 1-3/32 Inch 1/2 Inch Reduced Shank

The Irwin Hanson 90170 is a high-speed steel drill bit designed for precision drilling in metal, wood, and plastic applications. This professional-grade bit features a 1-3/32 inch diameter cutting head with a 1/2 inch reduced shank design, allowing it to be used in standard 1/2 inch drill chucks while providing the drilling capacity of a larger bit.

Key Features:

• High-speed steel construction for durability and heat resistance
• 1-3/32 inch (1.09375 inch) diameter for precise hole sizing
• 1/2 inch reduced shank fits standard drill chucks
• 6 inches overall length for extended reach and drilling depth
• Suitable for drilling metal, wood, and plastic materials
• Packaged in protective tube for storage and organization

The reduced shank design is ideal for applications requiring larger diameter holes without upgrading to a specialized drill chuck. High-speed steel construction provides excellent wear resistance and maintains sharp cutting edges even under demanding conditions.
