Irwin 1/16" x 1-7/8" Cobalt HSS 135 Degree Drill Bit (63104)

The Irwin 1/16" x 1-7/8" Cobalt HSS 135 Degree Drill Bit (63104) is a professional-grade cutting tool designed for efficient and reliable performance in demanding applications. This jobber length drill bit is specifically engineered to handle the challenges of drilling into tough metals, including hardened steel and abrasive alloys. The core of its effectiveness lies in its premium M35 cobalt high-speed steel construction, which provides exceptional resistance to high heat and abrasion, allowing the cutting edge to maintain its integrity and sharpness over extended use.

KEY FEATURES AND BENEFITS:

• 135° Split Point Tip: Starts drilling instantly on contact with the material, reducing the need for a pilot hole and preventing the bit from "walking" or wandering across the surface. This design ensures accurate hole placement with less pressure.
• Cobalt High-Speed Steel (HSS) Construction: The M35 cobalt steel composition provides high resistance to heat and abrasion. This material choice is essential for maintaining the cutting edge's sharpness and extending the bit's life when used on hard, tough, and abrasive metals.
• Heavy-Duty Performance: Engineered to excel in tough metal drilling applications, including heavy-duty abrasive alloy metal drilling and working with hardened (heat-treated) steel. Its robust design allows for reliable performance in challenging conditions.

SPECIFICATIONS:

• Size: 1/16"
• Material: Cobalt High-Speed Steel (HSS)
• Point Angle: 135 degrees
• Shank Type: Straight
• Point Type: Split-Point
• Series: 3016/631
• Model Number: 63104

HOW TO USE:

1. Secure the Bit: Insert the straight shank of the drill bit into the chuck of your drill. Tighten the chuck securely to prevent the bit from slipping during use.
2. Mark the Spot: Mark the precise location where you intend to drill. The 135° split point on this bit is designed to start drilling on its own, but a clear mark helps with alignment.
3. Apply Consistent Pressure: Begin drilling by applying firm, consistent pressure. The split-point tip will begin to cut immediately, so there is no need for excessive force to get the hole started.
4. Control Speed and Feed: Use a suitable drill speed for the material you are drilling. For harder metals, a lower speed is generally recommended to prevent overheating. Allow the bit's design to do the work and let the heavy-duty flutes eject the chips.
5. Clean and Cool: Periodically clear chips from the hole and consider using a cutting fluid, especially when working with very hard materials. This helps to reduce friction, dissipate heat, and extend the life of the bit.

BENEFITS OF USING IRWIN 1/16" X 1-7/8" COBALT HSS 135 DEGREE DRILL BIT (63104):
