Irwin 3-1/8″ Carded Cobalt 135 Degree Jobber Drill Bit (3016010)

Description

Irwin 3-1/8″ Carded Cobalt 135 Degree Jobber Drill Bit (3016010) is a high-performance drilling tool designed for demanding applications in tough materials. Constructed from high-speed steel reinforced with 5% cobalt alloy, it delivers exceptional resistance to heat and abrasion, making it ideal for drilling hardened and abrasive metals. The 135° split-point tip is self-centering, enabling immediate drilling on contact while preventing “walking” on the work surface, resulting in clean and accurate holes without the need for a center punch. Featuring a straight shank, this bit is compatible with a wide range of standard drill chucks, ensuring versatility and ease of use across multiple projects.

KEY FEATURES AND BENEFITS:

• Cobalt Alloy Construction: Made from high-speed steel with 5% cobalt for superior heat and abrasion resistance.
• 135° Split-Point Tip: Self-centers for immediate drilling without wandering, eliminating the need for a center punch.
• Versatile Compatibility: Straight shank fits standard drill chucks for use in various applications.
• Precision Drilling: Designed to produce clean, accurate holes in tough metals.

SPECIFICATIONS:

• Drill Diameter: 5/32 in.
• Overall Length: 3-1/8 in.
• Flute Length: 2 in.
• Shank Diameter: 5/32 in.
• Shank Type: Straight Shank
• Point Angle: 135 degrees
• Material: Cobalt High Speed Steel

HOW TO USE:

1. Safety First: Wear proper PPE, including safety glasses and gloves, before using power tools.
2. Secure the Workpiece: Clamp the material firmly to a stable surface to prevent movement during drilling.
3. Install the Bit: Insert the straight shank of the drill bit into the drill chuck and tighten securely.
4. Set the Drill Speed: Adjust to a slower speed for harder metals to avoid overheating.
5. Start Drilling: Position the bit on the drilling mark and allow the 135° split-point to self-center before applying steady pressure.
6. Maintain Consistent Pressure: Let the bit do the cutting, clear chips periodically, and use cutting lubricant for extended life.
7. Clean Up: Remove the bit after drilling and clean away any remaining chips or debris.

BENEFITS OF USING IRWIN 3-1/8″ CARDED COBALT 135 DEGREE JOBBER DRILL BIT (3016010):
