Irwin 11/64" x 3-1/4" Cobalt HSS 135 Degree Drill Bit (63111)

The Irwin 11/64" x 3-1/4" Cobalt HSS 135 Degree Drill Bit (63111) is a high-performance tool engineered for demanding metal drilling applications. Crafted from M-35 high-speed steel with 5% cobalt, this bit is specifically designed to handle extreme heat and abrasion encountered when working with tough materials. The cobalt alloy steel construction provides enhanced longevity and cutting efficiency, making it an ideal choice for professionals and serious hobbyists alike. The 11/64" diameter and jobber-length design make it a versatile tool for various tasks. Its gold oxide finish offers added corrosion resistance, contributing to the bit's extended life. This drill bit is particularly effective on difficult-to-cut metals such as hardened steel, stainless steel, and titanium. The advanced design, including a 135-degree split point, eliminates the need for a center punch and prevents the bit from "walking" on the workpiece, ensuring a clean and accurate start every time. The heavy-duty spiral flutes efficiently remove chips, reducing heat buildup and preventing clogging, which further improves drilling speed and bit life.

KEY FEATURES AND BENEFITS:

• M-35 Cobalt Alloy Steel: The 5% cobalt composition in the high-speed steel provides superior heat and abrasion resistance, significantly extending the bit's life and performance when drilling through tough, abrasive metals.
• 135-Degree Split Point: This self-centering feature prevents the bit from wandering or "walking" at the start of drilling, allowing for precise holes without the need for a pilot hole or center punch. It also reduces the required feeding pressure.
• Heavy-Duty Construction: Engineered with heavy-duty spiral flutes for fast chip ejection and shorter cutting lips to minimize torque, this bit is built for aggressive drilling into high-tensile materials.
• Gold Oxide Finish: The gold oxide coating adds a layer of protection against corrosion and provides a smoother surface for reduced friction and heat during operation, which contributes to a longer tool life.
• Versatile Application: This drill bit is optimized for drilling through a variety of hard metals, including hardened steel, stainless steel, and titanium, making it a valuable addition to any workshop.

HOW TO USE:

1. Safety First: Always wear appropriate personal protective equipment, including safety glasses and gloves, before beginning any drilling operation.
2. Secure the Workpiece: Clamp the material you are drilling into firmly to prevent it from moving. A loose workpiece can lead to inaccurate holes and potential injury.
3. Insert the Drill Bit: Insert the Irwin 63111 drill bit into your drill chuck and tighten it securely. Ensure the bit is centered and fully seated to prevent slippage.
4. Set Drill Speed: Adjust your drill speed to a lower setting, especially when working with hard metals. Slower speeds help to prevent the bit from overheating and losing its hardness.
5. Begin Drilling: Position the drill bit directly on the mark where you want to drill. The split point will prevent it from walking. Apply steady, moderate pressure and allow the bit to do the cutting. Do not force it.
6. Lubricate as Needed: For best results and to extend the life of the drill bit, use a cutting fluid or lubricant, especially when drilling into hard metals like stainless steel. This helps to dissipate heat and clear chips.
7. Clear Chips: Occasionally back the drill bit out of the hole to clear chips and debris, which prevents clogging and overheating.

BENEFITS OF USING IRWIN 11/64" X 3-1/4" COBALT HSS 135 DEGREE DRILL BIT (63111):

• Extended Tool Life: The M-35 cobalt steel composition provides high heat resistance, meaning the bit stays sharp longer, even under high-stress drilling conditions.
• Reduced Effort: The split point design allows for immediate penetration with less pressure required, reducing user fatigue and improving drilling efficiency.
• Enhanced Accuracy: The self-centering tip eliminates bit walking, ensuring that your holes are started precisely where you intend them to be.
• Versatile Performance: This bit is engineered to perform exceptionally well on a wide range of materials, particularly those that are typically difficult for standard HSS bits.
• Improved Chip Ejection: The heavy-duty spiral flute design efficiently removes material from the hole, preventing blockages and maintaining a cooler cutting temperature.
