Irwin 1/8″ Cobalt 135 Degree Jobber Length Drill Bit (63108)

Description

The Irwin 1/8″ Cobalt 135 Degree Jobber Length Drill Bit (63108) is a professional-grade cutting tool engineered to perform in the most demanding drilling applications. Made from a high-speed steel alloy with a high percentage of cobalt, this bit is specifically designed to handle the intense heat and friction generated when working with hard metals. Its specialized construction allows it to cut through materials like hard steel, stainless steel, titanium, and other abrasive alloys without losing its edge.

KEY FEATURES AND BENEFITS:

• The 135-degree split point tip is a critical feature, providing a self-centering action that prevents the bit from “walking” on the workpiece, which leads to more accurate and cleaner hole starts.
• This design also reduces the force needed to begin drilling.
• The heavy-duty web construction adds significant strength and rigidity, minimizing the risk of breaking, especially when drilling into tough materials.
• The heavy-duty spiral flutes are designed to efficiently evacuate chips and debris, preventing overheating and extending the life of the bit.
• A gold oxide finish reduces friction, contributing to cooler operation and further longevity.

SPECIFICATIONS:

• Model Number: 63108
• Diameter: 1/8 inch
• Point Angle: 135 degrees
• Material: High-speed steel with cobalt
• Finish: Gold Oxide
• Point Type: Split Point
• Shank Type: Straight

HOW TO USE:

1. Select the correct speed: Before you begin, set your drill to a low to medium speed. Drilling hard metals at high speeds generates excessive heat, which can damage the bit.
2. Secure the material: Clamp your workpiece firmly to a stable surface to prevent it from moving during drilling.
3. Insert the bit: Place the bit securely into your drill chuck, ensuring it is centered and tightened.
4. Apply consistent pressure: Start drilling with firm, steady pressure. The split-point tip will help guide the bit into the material. Avoid applying excessive force, as this can cause the bit to overheat or break.
5. Use cutting fluid: For best results, apply a cutting lubricant to the drilling area. This will help cool the bit and the workpiece, improve the finish of the hole, and extend the life of the bit.
6. Clear chips: The spiral flutes are designed to clear chips, but periodically withdrawing the bit slightly from the hole can help remove any remaining debris.

BENEFITS OF USING IRWIN 1/8″ COBALT 135 DEGREE JOBBER LENGTH DRILL BIT (63108):

• This bit’s high cobalt content provides superior resistance to heat and abrasion, which is essential for drilling into tough, high-tensile-strength materials.
• The 135-degree split point design minimizes bit wandering and the need for a pilot hole, saving time and ensuring precision.
• The heavy-duty construction and spiral flutes are engineered to withstand rigorous use, offering a longer service life than standard high-speed steel bits.
• The gold oxide finish also aids in reducing friction, which results in a smoother drilling process and a cleaner hole.

FEATURES:

• Precision-ground split point tip for immediate and accurate starts.
• Cobalt high-speed steel alloy construction for enhanced heat resistance.
• Optimized for drilling into hard metals like stainless steel, titanium, and abrasive alloys.
• Heavy-duty web design provides increased rigidity and strength.
• Cylinder/straight shank is compatible with a wide range of drill chucks.
• Gold oxide finish for reduced friction and extended bit life.
