Milwaukee 1/2″ x 12″ Black Oxide Aircraft Drill Bit 48-89-2776

EXTENDED REACH PRECISION FOR DEEP-BORE APPLICATIONS

When standard length bits fall short of the mark, the Milwaukee 48-89-2776 provides the necessary 12-inch reach required for deep drilling through thick timber, metal framing, or PVC assemblies. Engineered with a 135 split point, this bit eliminates the need for center punching by biting into the material immediately upon contact, preventing the bit from walking across the workpiece. The black oxide geometry is specifically treated to manage heat friction and resist corrosion, ensuring the cutting edges maintain their integrity over repeated high-torque cycles. For the professional, the 3-Flat Secure-Grip shank is a critical mechanical advantage, locking the bit into any 3/8″ or 1/2″ chuck to prevent the slipping that often plagues round-shank bits during heavy resistance.

• / 12-Inch Aircraft Length provides maximum reach for deep-hole drilling and hard-to-access areas.
• / 135 Split Point Tip starts on contact to deliver precise hole placement without the need for a pilot hole.
• / 3-Flat Secure-Grip Shank prevents the bit from spinning in the chuck under high-load drilling.
• / Corrosion Resistant Black Oxide coating provides essential lubricity to reduce heat buildup and extend bit life.
• / Reduced 3/8″ Shank allows for the use of this 1/2″ diameter bit in standard 3/8″ drill chucks.
