Irwin 1/2″ x 6″ Cobalt HSS 135 Degree Drill Bit (63132)

Description

The Irwin 1/2″ x 6″ Cobalt HSS 135 Degree Drill Bit (63132) is a high-performance tool crafted for professionals who regularly work with tough, abrasive metals. This jobber-length bit combines a specialized material composition with a precise tip geometry to deliver clean, accurate holes in materials that would quickly dull a standard drill bit. The M-35 cobalt alloy is a key component, providing superior resistance to the extreme heat and friction generated when drilling through materials like stainless steel and titanium.

KEY FEATURES AND BENEFITS:

• M-35 Cobalt Alloy Construction: This high-speed steel alloy contains 5-8% cobalt, providing excellent resistance to heat and abrasion. This extends the bit’s life when used on tough materials like hardened steel and stainless steel.
• 135° Split Point Tip: The self-centering design allows the bit to start drilling on contact with less force, preventing “walking” and eliminating the need for a pilot hole.
• Heavy-Duty Spiral Flute: Engineered for fast chip ejection, this design keeps the cutting edge clear of debris, reducing heat buildup and maintaining drilling efficiency.
• Gold Oxide Finish: This finish reduces friction between the bit and the workpiece, further decreasing heat and extending the bit’s operational life.
• Jobber Length: The balanced 6″ overall length provides a good combination of reach and stability for a variety of drilling tasks.

SPECIFICATIONS:

• Cutting Direction: Right-hand
• Finish: Gold oxide

HOW TO USE:

1. Preparation: Always wear appropriate safety gear, including safety glasses. Secure the material you are drilling into to prevent it from moving. Mark the exact spot where you want to drill.
2. Chuck the Bit: Insert the 1/2″ 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 during operation.
3. Set Your Speed: For tough metals, use a lower drill speed. High speeds can generate excessive heat, which can damage the bit and the material.
4. Start Drilling: Place the tip of the bit on your mark. Apply steady, firm pressure to begin drilling. The 135° split point will self-center, so there is no need to apply extreme force.
5. Cooling and Lubrication: For best results and to extend the life of the bit, use a cutting fluid or lubricant, especially when drilling into stainless steel and other hard metals.
6. Drill Through: Maintain steady pressure and a consistent speed as you drill. Allow the bit’s flutes to eject the chips. If you feel resistance or hear a screeching sound, you may be pushing too hard or need more lubrication.
