Irwin 9/32″ Carded Cobalt 135 Degree Jobber Drill Bit (3016018)

Description

The Irwin 9/32″ Carded Cobalt 135 Degree Jobber Drill Bit (3016018) is a specialized cutting tool designed for exceptional performance in hard and abrasive materials. Constructed from a cobalt-enhanced high-speed steel, this drill bit is formulated to withstand the high heat and friction generated when drilling tough metals like stainless steel, cast iron, and titanium. The 135-degree split point tip is a standout feature, enabling the bit to start drilling on contact without walking, which is a common problem with conventional drill bits. This design not only improves accuracy but also reduces the amount of force required from the user. As a result, it is the ideal choice for professionals and enthusiasts who demand precision and reliability in their metalworking tasks. The jobber length provides a balanced combination of reach and rigidity, making it a versatile addition to any toolbox. This drill bit is engineered for those tough jobs where standard high-speed steel bits would fail, ensuring that you can complete your projects with efficiency and confidence.

KEY FEATURES AND BENEFITS:

• Exceptional Heat Resistance: Cobalt alloy composition increases the bit’s ability to withstand high temperatures, extending tool life and maintaining sharpness.
• Precise, Walk-Free Starts: 135-degree split point tip allows drilling on contact without walking, eliminating the need for a center punch.
• Superior Material Penetration: Efficiently drills through tough metals such as stainless steel, hardened alloys, and cast iron.
• Increased Tool Life: Durable design and cobalt material maintain a sharp cutting edge longer, reducing replacements.
• Improved User Efficiency: Requires less feed pressure, reducing fatigue and improving control during drilling.
