Irwin 9/64″ x 2-7/8″ Cobalt HSS 135 Degree Drill Bit (63109)

Description

The Irwin 9/64″ x 2-7/8″ Cobalt HSS 135 Degree Drill Bit (63109) is a high-performance tool engineered for drilling through the toughest materials. Crafted from M-35 high-speed steel with a 5% cobalt blend, this drill bit is specifically designed to withstand the high temperatures and friction generated when working with hardened metals. The inclusion of cobalt significantly enhances its heat and abrasion resistance, providing a longer service life and consistent cutting performance. The heavy-duty spiral flute design ensures fast and effective chip ejection, preventing material build-up and maintaining a clean cut. A standout feature is the 135-degree split point tip, which allows for immediate, accurate starts on the workpiece without the need for a center punch. This design reduces feed pressure, eliminates “bit walking,” and prevents work hardening, making it an indispensable tool for professionals and serious DIYers tackling demanding projects.

KEY FEATURES AND BENEFITS:

• Superior Material Composition: Made from M-35 high-speed steel with a 5% cobalt blend, this bit offers exceptional resistance to heat and wear. This allows it to maintain its sharpness longer when drilling into tough materials like stainless steel, hardened steel, and titanium.
• 135-Degree Split Point Tip: The innovative tip design provides immediate, accurate starts, eliminating the common problem of “bit walking” on the material’s surface. It also reduces the force required to begin drilling, resulting in a smoother, more controlled operation.
• Fast Chip Ejection: The robust spiral flute is engineered for efficient removal of chips and debris from the hole. This prevents clogging, reduces heat buildup, and ensures a cleaner, more consistent hole.
• Versatile Application: This drill bit is optimized for drilling into a wide range of hard-to-machine materials, including alloy metals and high-tensile strength metals, making it a versatile addition to any professional’s toolkit.

SPECIFICATIONS:

• Drill Diameter: 9/64 inches
• Overall Length: 2-7/8 inches
• Flute Length: 1-3/4 inches
• Shank Diameter: 9/64 inches
• Shank Length: 1-1/8 inches
• Material: M-35 Cobalt High-Speed Steel (5% Cobalt)
• Point Angle: 135 Degrees
• Cutting Direction: Right-Hand (Clockwise)

HOW TO USE:

1. Preparation: Always wear appropriate personal protective equipment, including safety glasses. Secure your workpiece firmly in a vise or with clamps to prevent it from moving during drilling.
2. Mounting the Bit: Insert the drill bit into the chuck of your drill. Ensure the shank is centered and securely tightened to prevent the bit from slipping or wobbling.
3. Setting the Speed: Select an appropriate drilling speed. For hard materials like steel and stainless steel, a lower RPM is generally recommended to prevent overheating and premature wear of the bit.
4. Drilling: Apply steady, consistent pressure to the drill. The 135-degree split point will help the bit start without walking. Use a cutting fluid or lubricant to further reduce friction and heat, which will extend the life of the bit and improve the quality of the cut.
5. Clearing Debris: Periodically pull the drill bit out of the hole to allow chips to clear from the flutes. This is especially important for deeper holes to prevent clogging.
