Irwin 13/64″ x 3-5/8″ Cobalt HSS 135 Degree Drill Bit (63113ZR)

Description

The Irwin 13/64″ x 3-5/8″ Cobalt HSS 135 Degree Drill Bit (63113ZR) is a precision-engineered tool designed for the most demanding metal drilling applications. As part of Irwin’s Series 3016/631, this jobber-length drill bit is crafted from a premium M35 High-Speed Steel (HSS) alloyed with 5% cobalt. This specific blend of materials gives the bit exceptional resistance to both high heat and abrasion, which are common challenges when working with hardened or abrasive metals. The 13/64-inch diameter is a common fractional size, making it useful for a variety of tasks where a clean, accurately sized hole is required. The gold oxide finish on the bit adds a layer of protection and lubricity, further enhancing its performance and lifespan.

KEY FEATURES AND BENEFITS:

• Superior Material Composition: The M35 High-Speed Steel with 5% cobalt provides exceptional heat and abrasion resistance, significantly extending the bit’s life and performance in tough materials. This means you can drill longer and more efficiently without the bit losing its edge.
• 135° Split-Point Tip: This design allows the bit to start on contact, preventing it from “walking” or slipping on the surface. The benefit is more accurate hole placement and the ability to drill without a center punch in many cases.
• Optimal Flute Design: The heavy-duty spiral flutes are engineered for fast and effective chip ejection, which helps to prevent material buildup and reduces heat. This keeps the bit cooler and improves the overall drilling process.
• Versatile Application: Specifically designed for heavy-duty metal drilling, this bit is a reliable tool for working with hard materials such as hardened steel, stainless steel, and titanium.
• Precision and Control: The combination of the split-point tip and straight shank provides the user with enhanced control and stability, resulting in cleaner and more precise holes.

HOW TO USE:

1. Preparation: Always wear appropriate personal protective equipment, including safety glasses. Secure your workpiece firmly to a workbench or with a vise to prevent it from moving during the drilling process.
2. Drill Setup: Insert the straight shank of the Irwin 63113ZR drill bit into your drill’s chuck. Tighten the chuck securely to ensure the bit is centered and will not slip.
3. Speed and Pressure: Start the drill at a lower speed and apply moderate, consistent pressure. Avoid using excessive force, as this can generate heat and shorten the bit’s life.
4. Coolant: For drilling tough metals, using a cutting fluid or lubricant is highly recommended to dissipate heat and extend the life of the drill bit. Apply the coolant to the drilling area as you work.
5. Drilling: As the bit begins to cut, maintain a steady feed rate. The 135° split point will allow it to penetrate without walking.
6. Cleanup: Once the hole is complete, carefully retract the drill bit while the drill is still running to clear any remaining chips. Turn off the drill and remove the bit from the chuck.

BENEFITS OF USING IRWIN 13/64″ X 3-5/8″ COBALT HSS 135 DEGREE DRILL BIT (63113ZR):

• Increased tool life when drilling hard, abrasive, or heat-treated metals.
• More accurate and cleaner hole starting due to the specialized tip design.
• Reduced user effort and improved drilling speed in challenging materials.
• Reliable performance in professional and heavy-duty applications.
• Eliminates the need for a separate pilot hole in many cases, saving time.
• Enhanced heat resistance helps prevent the bit from overheating and failing.

FEATURES:

• M35 HSS construction enriched with 5% cobalt for superior durability.
• 135-degree split point design to prevent bit walking on initial contact.
• Straight shank configuration compatible with all standard drill chucks.
• Gold oxide finish for added protection and reduced friction.
• Jobber length flutes for effective chip removal and deep hole drilling.
• Engineered specifically for performance in hard-to-drill metals.
