Irwin 11/32″ Cobalt 135 Degree Jobber Length Drill Bit (63122)

Description

The Irwin 11/32″ Cobalt 135 Degree Jobber Length Drill Bit (63122) is specifically engineered for high-performance drilling in abrasive and hard-to-machine materials. Its construction from M35 High-Speed Steel with 5% cobalt provides exceptional heat and abrasion resistance, making it an ideal choice for professionals who regularly work with tough metals. The 135-degree split point design is a key feature, as it allows the bit to start on contact without the need for a center punch, reducing “walking” and ensuring precise hole placement from the beginning. This design also reduces the amount of pressure needed to start a hole, leading to a smoother and more efficient drilling process.

KEY FEATURES AND BENEFITS:

• High-Performance Material: Made from M35 High-Speed Steel with 5% Cobalt, providing superior heat and abrasion resistance for extended tool life, especially when drilling through hardened or abrasive metals.
• Precision Drilling: The 135-degree split point tip prevents the bit from walking and allows for immediate, accurate starts without a pilot hole, which is crucial for precision work.
• Efficient Chip Removal: The spiral flute design is optimized to quickly and effectively eject chips, which helps to minimize heat buildup and prevents clogging for a smoother drilling experience.
• Versatile Application: This bit is specifically suited for a wide range of tough materials, including stainless steel, titanium, and other hard alloys, making it a valuable tool for various professional and industrial tasks.
• Corrosion Resistance: A gold oxide finish helps to protect the drill bit from rust and corrosion, maintaining its cutting performance and extending its overall lifespan.

HOW TO USE:

1. Preparation: Ensure your drill is compatible with the 11/32″ shank size. Select a drilling speed appropriate for the material you are working with; generally, harder materials require lower speeds.
2. Secure Material: Securely clamp the workpiece to prevent it from moving during drilling. Use a sturdy vise or clamps.
3. Position Bit: Position the bit on the desired drilling location. The 135-degree split point will help the bit start without walking.
4. Begin Drilling: Apply steady, even pressure and start the drill. Avoid excessive force, which can overheat and dull the bit. Let the bit’s cutting action do the work.
5. Cooling: For drilling hard metals, it is recommended to use a cutting fluid to keep the bit cool and to help with chip evacuation. This will significantly extend the bit’s life.
6. Clear Chips: Periodically withdraw the bit from the hole to clear chips, especially in deep holes.
