Description
The Irwin 11/16" x 6" Silver & Deming Drill Bit (91144) is a specialized tool engineered for heavy-duty drilling applications. This premium high-speed steel bit is designed to create large holes in various materials, including metal, wood, and plastic. Its unique Silver & Deming design features a reduced 1/2-inch shank, allowing the larger 11/16-inch bit to be used with standard 1/2-inch drill chucks. The shank is also equipped with three flats, which provides a secure grip to prevent slippage during high-torque applications. A black oxide coating protects the bit from corrosion and wear, extending its lifespan. The 118° chisel point is ideal for general-purpose drilling, making this tool a versatile and reliable choice for professionals in automotive, body shop, and metal fabrication fields.

HOW TO USE:
- Select the Right Drill: Ensure your drill has a 1/2" chuck to accommodate the bit's shank.
