Irwin 5/64" x 2" Cobalt HSS 135 Degree Drill Bit (63105ZR)

The Irwin 5/64" x 2" Cobalt HSS 135 Degree Drill Bit (63105ZR) is a premium tool crafted for professionals who demand precision and performance. Made from M-35 high-speed steel with a 5% cobalt alloy, this heavy-duty jobber length bit is designed to withstand the rigors of drilling into the most challenging materials. The cobalt content significantly increases its heat resistance and wear life, making it a reliable choice for applications involving hard metals, stainless steel, and titanium. The 135-degree split point is a key feature, as it eliminates the need for a pilot hole by preventing the bit from "walking" at the start of a cut, ensuring a clean and accurate entry every time. Its heavy-duty spiral flute design efficiently removes chips, reducing clogging and further enhancing its cutting efficiency. With its gold oxide finish, this drill bit is built for superior durability and a long service life, providing consistent results on every job.

KEY FEATURES AND BENEFITS:

• Cobalt M-35 HSS Construction: The M-35 high-speed steel with a 5% cobalt alloy composition provides exceptional heat resistance and extended bit life, making it highly effective for drilling abrasive and tough metals.
• 135-Degree Split Point: This precision-ground point allows for a quick, accurate start on the workpiece without the bit wandering. It reduces the required feed pressure, making drilling easier and more controlled.
• Heavy-Duty Jobber Length: The jobber length design offers a balance of strength and reach, making it versatile for a variety of drilling tasks in professional settings.
• Efficient Chip Removal: The heavy-duty spiral flute is engineered for fast and effective chip ejection, which helps prevent clogging and heat buildup, extending the life of the bit and improving cutting performance.
• Gold Oxide Finish: This surface treatment adds a layer of protection against corrosion and friction, enhancing the overall durability and longevity of the drill bit.

HOW TO USE:

1. Prepare the Workpiece: Secure your workpiece firmly in a vise or with clamps to prevent movement during drilling. Mark the exact location for the hole with a center punch to guide the bit.
2. Select the Right Drill: Insert the Irwin 5/64" Cobalt HSS Drill Bit into your drill chuck. Tighten the chuck securely to ensure the bit is centered and will not slip.
3. Start Drilling: Begin drilling at a slow speed, applying steady, moderate pressure. The 135-degree split point will initiate the cut without the need for a pilot hole.
4. Increase Speed and Apply Lubricant: Once the bit has started the cut, you can increase the drill speed. For hard metals, use a cutting fluid or lubricant to reduce friction and heat, which will extend the bit's life and improve cutting performance.
5. Clear Chips: Periodically withdraw the drill bit from the hole to allow chips to clear. This prevents clogging and overheating, especially when drilling deeper holes.
6. Complete the Hole: Continue drilling until the desired depth is reached. Once the hole is complete, back the drill out slowly while it is still spinning to prevent the bit from getting stuck.

BENEFITS OF USING IRWIN 5/64" X 2" COBALT HSS 135 DEGREE DRILL BIT (63105ZR):

• Exceptional Longevity: The 5% cobalt alloy construction provides superior resistance to heat and abrasion, allowing the bit to last significantly longer than standard HSS bits, especially in high-temperature applications.
• Precise and Clean Starts: The 135-degree split point design ensures the bit starts exactly where you want it to, preventing walking and eliminating the need for a pilot hole, which saves time and improves accuracy.
• Superior Performance on Hard Materials: This drill bit is specifically engineered to handle tough metals like stainless steel, cast iron, and titanium, providing consistent and reliable results where other bits might fail.
• Increased Efficiency: The heavy-duty spiral flute design quickly and efficiently evacuates chips, keeping the cutting area clear and reducing the risk of overheating and bit breakage.
• Cost-Effective Tooling: Because of its enhanced durability and long life, this drill bit provides a better return on investment, reducing the frequency of replacements and the associated costs.
