Milwaukee 1/8" x 12" Aircraft Length Black Oxide Drill Bit

EXTENDED REACH PRECISION FOR DEEP-HOLE DRILLING APPLICATIONS

When standard length bits fall short in deep-cavity metalwork or structural framing, the Milwaukee 48-89-2770 provides the critical 12-inch reach required for professional-grade accuracy. Engineered with a heavy-duty black oxide coating, this bit reduces friction and heat buildup, significantly extending tool life in demanding materials like PVC, wood, and non-ferrous metals. The 135° split point geometry is a mechanical necessity for high-torque drilling, ensuring the bit bites immediately upon contact without the need for a center punch, while the 3-flat Secure-Grip™ shank eliminates the common failure point of bit slippage within the chuck under heavy load.

• / 12-Inch Aircraft Length provides the necessary clearance for drilling through thick assemblies or reaching into obstructed spaces.
• / 135° Split Point Tip eliminates walking on contact, ensuring precise hole placement in metal and hard plastics.
• / Black Oxide Coating offers superior lubricity and corrosion resistance for consistent performance in high-heat applications.
• / 3-Flat Secure-Grip™ Shank prevents the bit from spinning in the chuck, maximizing torque transfer and protecting the tool.
