Irwin 3/16″ Cobalt 135 Degree Jobber Length Drill Bit (63112)

Description

The Irwin 3/16″ Cobalt 135 Degree Jobber Length Drill Bit (63112) is a specialized cutting tool designed for professionals who require high performance when working with demanding materials. This bit is not a general-purpose drill bit; it is engineered with a specific purpose in mind: to drill through hard, abrasive, and difficult-to-machine metals with accuracy and consistency. The core of its effectiveness lies in its M-42 cobalt high-speed steel construction, which provides exceptional resistance to heat and abrasion—the two primary causes of failure when drilling tough metals like stainless steel, titanium, and cast iron.

KEY FEATURES AND BENEFITS:

• Exceptional Heat and Abrasion Resistance: The M-42 cobalt steel alloy provides superior hardness and heat resistance, allowing the bit to maintain its cutting edge even when drilling through tough, high-heat generating materials like stainless steel, titanium, and hardened steel. This results in a longer bit life and consistent performance.
• Precision and Control: The 135-degree split point tip is self-centering, which prevents the bit from wandering at the start of a hole. This eliminates the need for a center punch and ensures a clean, accurate entry point every time, reducing the chance of error and workpiece damage.
• Efficient Chip Removal: The heavy-duty spiral flute design is optimized for fast and efficient removal of chips and debris from the hole. This prevents material from building up, which can cause overheating and potential bit failure, thereby improving the drilling speed and overall tool life.

SPECIFICATIONS:

• Size: 3/16″
• Material: Cobalt M-42 High-Speed Steel
• Drill Point: 135-Degree Split Point
• Overall Length: 3-1/2″
• Shank: Straight
• Twist Length: 1-1/8″

HOW TO USE:

1. Preparation: Ensure your workpiece is securely clamped to a stable surface to prevent it from moving during drilling. Select the appropriate drill and ensure the chuck is tightened properly around the bit.
2. Lubrication: For best results when drilling hard metals, apply a cutting fluid or lubricant to the drilling location. This will help cool the bit, reduce friction, and extend its lifespan.
3. Start Drilling: Begin drilling at a low to medium speed. The 135-degree split point should engage the material without slipping. Apply steady, firm pressure, but do not force the bit.
4. Maintain Speed and Pressure: Continue drilling with consistent speed and pressure, allowing the bit to cut the material. The heavy-duty flutes will remove the chips from the hole as you drill.
5. Cooling: Periodically lift the bit from the hole to allow it to cool and to clear chips, especially when drilling deep holes or very hard materials. Reapply lubricant as needed.

BENEFITS OF USING IRWIN 3/16″ COBALT 135 DEGREE JOBBER LENGTH DRILL BIT (63112):
