Irwin 5/32″ Cobalt 135 Degree Jobber Length Drill Bit (63110)

Description

The Irwin 5/32″ Cobalt 135 Degree Jobber Length Drill Bit (63110) is a high-performance tool engineered for drilling into demanding materials. Constructed from M-35 Cobalt High-Speed Steel, this drill bit is specifically designed to withstand the high temperatures and abrasion that come with cutting through tough metals like stainless steel, hard steel, and titanium. Its robust heavy-duty web construction provides exceptional strength, while the unique 135° split point tip ensures a precise and clean start on the workpiece, minimizing the chance of the bit “walking” and eliminating the need for a center punch. The gold oxide finish helps to increase the bit’s life and resistance to wear. Ideal for professionals and DIY enthusiasts tackling heavy-duty projects, this bit delivers reliable performance and clean, accurate holes in the most challenging applications.

KEY FEATURES AND BENEFITS:

• M-35 Cobalt High-Speed Steel: Made from a premium alloy that provides superior heat and abrasion resistance, extending the bit’s lifespan when drilling into hard materials like stainless steel and titanium.
• 135° Split Point Tip: This self-centering design allows for an immediate, accurate start without the need for a center punch, reducing the risk of bit walking and ensuring clean, precise holes. It also decreases the required feed pressure, making drilling easier and more efficient.
• Heavy-Duty Web Construction: Provides increased strength and rigidity, making the bit more resistant to breakage and flexing under heavy load, which is crucial for demanding metal drilling applications.
• Gold Oxide Finish: A surface treatment that helps the bit resist wear and heat buildup, contributing to a longer tool life and smoother drilling performance.
• Jobber Length: This standard length provides a good balance of reach and rigidity, making it a versatile choice for a wide range of handheld and stationary drilling tasks.

SPECIFICATIONS:

• Cutting Diameter: 5/32 inches (5/32″)
• Shank Diameter: 5/32 inches (5/32″)
• Flute Length: 2 inches (2″)
• Cutting Direction: Right-Hand (clockwise)

HOW TO USE:

1. Preparation: Ensure your drill is set to the appropriate speed for the material you are drilling. Slower speeds are generally recommended for hard metals to prevent overheating. Secure your workpiece firmly in a vise or with clamps to prevent it from moving during drilling.
2. Lubrication: Apply a suitable cutting fluid or lubricant to the drilling area. This reduces friction and heat, which is essential for preserving the life of the cobalt bit and achieving a clean cut in hard metals.
3. Positioning: Place the tip of the drill bit directly on the mark where you intend to drill. The 135° split point will self-center, so no pre-punching is required.
4. Drilling: Begin drilling at a slow, steady speed, applying consistent pressure. Avoid excessive force, as this can cause the bit to overheat or break. Allow the bit to do the work.
5. Clearing Chips: Periodically back the bit out of the hole to clear chips and re-apply lubricant. This prevents chip buildup, which can cause heat and bind the bit.
6. Completion: Continue drilling until you have gone through the material. Once complete, slowly withdraw the bit from the hole.
