Irwin 3/16" x 3-1/2" Black Oxide HSS 135 Degree Drill Bit (63512)

The Irwin 3/16" x 3-1/2" Black Oxide HSS 135 Degree Drill Bit (63512) is a general-purpose, heavy-duty tool designed for reliable performance across a variety of materials. Constructed from M-2 High-Speed Steel and finished with a black oxide coating, this drill bit is built to resist heat and wear, ensuring a longer life and consistent cutting action. Its most notable feature is the 135-degree split point, which is self-centering and allows for immediate, accurate starts without the bit "walking" across the surface. This design significantly reduces the force needed to begin drilling, making it an excellent choice for use with portable drills and for precision work.

KEY FEATURES AND BENEFITS:

• Self-Centering 135° Split Point: The unique point angle allows the bit to start drilling on contact, eliminating the need for a center punch and preventing the bit from wandering. This provides greater accuracy and control, especially when using a handheld drill.
• M-2 High-Speed Steel (HSS) Construction: The high-quality steel alloy offers a balance of hardness and toughness, providing superior wear resistance and durability for a longer tool life.
• Black Oxide Finish: A protective coating that enhances lubricity, reducing friction and heat buildup during drilling. It also provides a barrier against corrosion, maintaining the bit's condition over time.
• Effective Chip Ejection: The spiral flute design is optimized for efficient chip removal, preventing material from packing in the hole. This ensures a smoother drilling process and reduces the risk of the bit overheating.
• Versatile Application: This general-purpose bit is suitable for drilling a broad spectrum of materials, including metal, wood, plastic, and stainless steel, making it a valuable addition to any toolbox.

HOW TO USE:

1. Prepare the material: Secure the workpiece firmly to prevent movement during drilling. Mark the exact location where you intend to drill.
2. Insert the bit: Insert the straight shank of the drill bit into the chuck of your drill. Tighten the chuck securely to ensure the bit is centered and will not slip.
3. Set the speed: Choose the appropriate drill speed for your material. Lower speeds are generally better for harder materials like metal, while higher speeds work well for softer materials like wood or plastic.
4. Start drilling: Position the tip of the bit on your marked spot. Apply steady, firm pressure to begin drilling. The 135° split point will help the bit start cleanly without walking.
5. Maintain pressure and clear chips: Maintain consistent pressure while drilling. If you are drilling a deep hole, periodically pull the bit out of the hole to clear chips and prevent the bit from overheating.
6. Finish drilling: Once the hole is complete, release the drill trigger and carefully remove the bit from the hole.
