Irwin 19/64" x 4-3/8" Titanium 135 Degree Drill Bit (63719)

The Irwin 19/64" x 4-3/8" Titanium 135 Degree Drill Bit (63719) is a professional-grade tool designed for high-performance drilling in metal. The Titanium Nitride (TiN) coating on the high-speed steel substrate provides exceptional resistance to heat and friction, which is the primary cause of bit wear. This advanced coating extends the bit's life up to six times longer than standard HSS bits, reducing the need for frequent replacements and saving you time and money.

KEY FEATURES AND BENEFITS:

• High-speed steel construction with a Titanium Nitride (TiN) coating for exceptional heat and friction resistance.
• Provides up to six times the lifespan of standard HSS bits.
• 135° split-point tip starts drilling on contact to prevent walking.
• Straight shank ensures compatibility with most standard chucks.
• Heavy-duty web design for stability, rigidity, and consistent performance.
• Shorter cutting lips reduce torque when drilling high-tensile materials.

SPECIFICATIONS:

• Diameter: 19/64 in.
• Overall Length: 4-3/8 in.
• Flute Length: 3-1/16 in.
• Material: High-Speed Steel (HSS) with Titanium Nitride (TiN) coating
• Point Angle: 135 degrees
• Shank Style: Straight
• Point Style: Split point

HOW TO USE:

1. Preparation: Always wear appropriate personal protective equipment, including safety glasses. Secure the material you are drilling into to prevent it from moving.
2. Installation: Insert the straight shank of the drill bit into the chuck of your drill or drill press. Tighten the chuck firmly to ensure the bit is centered and secure.
3. Positioning: Position the tip of the bit directly on the mark where you intend to drill. The 135° split-point tip will help the bit start immediately without walking.
4. Drilling: Start the drill at a moderate speed and apply steady, consistent pressure. Avoid applying excessive force, as this can generate heat and damage the bit. The bit’s design is optimized to reduce feed pressure, so let the tool do the work.
5. Cooling: For extended drilling in hard metals, consider using a cutting fluid or lubricant to dissipate heat and further extend the bit's life.
