Description
Irwin 5/16" x 12" Aircraft Extension HSS Fractional Drill Bit (62120) is designed for specialized drilling tasks requiring extended reach. Its 12-inch length allows access to tight or hard-to-reach areas where standard bits cannot reach, making it ideal for electricians, plumbers, and professionals working with cables or wiring in confined spaces. Constructed from premium high-speed steel with a black oxide finish, this drill bit offers excellent durability, corrosion resistance, and heat resistance. The 135° split-point tip ensures immediate and precise starts, preventing the bit from wandering and delivering clean, accurate holes every time.
KEY FEATURES AND BENEFITS:
- Extended Length: The 12-inch extension enables drilling in confined or awkward locations inaccessible to standard bits.
- 135° Split-Point Tip: Provides precise, immediate drilling starts without walking or slipping.
- High-Speed Steel Construction: Ensures strength and heat resistance for long-lasting sharpness.
- Black Oxide Coating: Protects against corrosion and reduces friction for smoother drilling.
- Versatile Use: Suitable for drilling wood, metal, and plastic materials.
SPECIFICATIONS:
- Model Number: 62120
- Drill Diameter: 5/16" (0.3125 inches)
- Overall Length: 12 inches
- Material: M-2 High-Speed Steel (HSS)

HOW TO USE:
- Preparation: Ensure the drill is off and securely held. Select the correct speed based on the material (lower for metal, higher for wood/plastic).
- Secure the Bit: Insert the straight shank into the drill chuck and tighten firmly to prevent slipping.
- Positioning: Place the tip on the marked drilling spot. The 135° split point will help maintain position.
- Drilling: Apply light, steady pressure and maintain consistent speed. Let the bit cut without forcing it.
