Irwin 1-1/4" x 6" Silver & Deming Drill Bit (90180)

The Irwin 1-1/4" x 6" Silver & Deming Drill Bit (90180) is a powerful and precise tool built for professionals who need to drill large holes with a standard 1/2-inch chuck. This heavy-duty drill bit is part of the trusted Irwin Silver and Deming series and is crafted from premium high-speed steel, a material known for its strength and ability to withstand high temperatures and abrasion. The bit's design features a reduced shank, allowing it to fit into standard drill chucks, a crucial advantage for jobs that require drilling larger diameters. A protective black oxide coating enhances the bit's longevity by providing resistance to corrosion. Whether you're working on automotive repairs, metal fabrication, or general-purpose drilling, this drill bit is engineered for consistent and reliable performance. The unique three-flatted shank design ensures a secure, no-slip grip, preventing the bit from rotating during use and increasing overall drilling safety and efficiency.

HOW TO USE:

1. Preparation: Always wear appropriate personal protective equipment (PPE), including safety glasses, when using power tools.
2. Secure the Bit: Loosen the chuck on your drill and insert the 1/2-inch reduced shank of the Irwin drill bit. Ensure that the three-flatted sides are aligned properly within the chuck to get the most secure grip. Tighten the chuck firmly to prevent any movement.
3. Setup: Mark the center of the hole you want to drill on your workpiece. Secure the material in a vise or clamp to prevent it from shifting.
4. Drilling: Start the drill at a slow speed and apply steady, consistent pressure. As the bit begins to cut, you can increase the speed gradually. Do not apply excessive force, as this can cause the bit to overheat or break.
5. Cooling: For drilling in metal, especially with larger bits, it's recommended to use a cutting fluid or lubricant to reduce friction and heat buildup. This helps to extend the life of the drill bit and improve drilling performance.
6. Finishing: Once the hole is complete, back the bit out slowly. Use a deburring tool to remove any sharp edges from the hole.
