Irwin 10502382 HSS Pro Drill Bit

The Irwin 10502382 HSS Pro Drill Bit is a precision-engineered high-speed steel (HSS) drill bit designed for demanding metalworking applications. Its compact size, robust construction, and advanced geometry make it an essential tool for professionals who require reliable performance on hard metals such as stainless steel, alloy steel, and titanium.

Key Features

• Material: Premium high-speed steel (HSS) with a hardened core that resists wear and maintains sharpness under high temperatures.
• Diameter: 3.3 mm (0.13 in), ideal for fine drilling tasks where precision is paramount.
• Length: 65 mm (2.56 in) overall length, providing sufficient reach while keeping the bit lightweight.
• Working Length: 36 mm (1.42 in), allowing for deep drilling into metal without compromising stability.
• Coating: Optional titanium nitride (TiN) or black oxide finish to reduce friction, extend life, and improve heat dissipation.
• Shank Design: Fluted shank for a secure fit in standard drill chucks, minimizing vibration during operation.

Design Excellence

The Irwin HSS Pro Drill Bit incorporates a double-flute geometry that enhances chip evacuation and reduces heat buildup. The flutes are engineered with a 45° angle to maximize cutting efficiency while maintaining structural integrity. This design ensures consistent performance even when drilling through tough alloys.

Applications

This drill bit excels in a variety of metalworking scenarios:

• Automotive Fabrication: Precision holes for engine components, brackets, and custom parts.
• Aerospace Engineering: Drilling into titanium and aluminum alloys where surface integrity is critical.
• Tooling and Die Making: Creating accurate pilot holes in hardened steel dies.
• Jewelry and Watchmaking: Fine drilling of precious metals for intricate designs.
• General Metal Fabrication: Cutting through stainless steel, mild steel, and other ferrous materials with ease.

Performance Characteristics

The combination of high-speed steel and advanced flute design delivers the following performance benefits:

• Extended Life: Reduced wear allows for longer drilling sessions before replacement is needed.
• Heat Resistance: Maintains cutting edge integrity at temperatures exceeding 800 °C.
• Low Vibration: Fluted shank and balanced geometry minimize chatter, resulting in smoother cuts.
• Consistent Accuracy: Tight tolerances ensure repeatable hole diameters across multiple uses.

Maintenance Tips

To maximize the lifespan of the Irwin HSS Pro Drill Bit, follow these best practices:

1. Use Proper Speed: Match drill speed to material hardness; for steel, a range of 200–400 RPM is recommended.
2. Apply Cutting Fluid: Lubricants reduce friction and heat buildup, especially when drilling thick sections.
3. Avoid Overheating: Pause periodically to allow the bit to cool if drilling deep holes.
4. Inspect Regularly: Check for chipping or dullness; replace immediately if performance degrades.
5. Store Correctly: Keep in a dry, protected environment to prevent corrosion.

Compatibility and Usage Notes

The bit’s standard shank size fits most handheld drills and CNC machines equipped with a 1/4‑inch chuck. It is compatible with both air‑driven and electric drilling systems, making it versatile for shop floor or field use.
