Milwaukee 48-89-2735 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2735 is a black oxide jobber length drill bit engineered for tradespeople who need reliable performance across metal, wood, and PVC. The Thunderbolt web design uses a thicker core than standard drill bits, delivering greater resistance to side-load breakage during demanding jobsite use. A 135-degree split point tip starts on contact without walking, and a parabolic flute geometry evacuates chips quickly to maintain cutting speed. The 3-flat Secure-Grip shank locks firmly in drill chucks to reduce slipping during operation. At 6 inches in length and 0.19 pounds, this bit is suited for portable drill use in tight or awkward positions.

This bit is appropriate for general trade applications including mechanical, electrical, plumbing, and light fabrication work. It performs on flat and curved surfaces and handles common jobsite materials including mild steel, aluminum, wood, and PVC pipe. The reduced shank diameter allows use in 3/8-inch chucks, making it compatible with a wide range of portable drills commonly found on residential and light commercial job sites. HVAC techs, plumbers, electricians, and general contractors will find this bit suitable for everyday drilling tasks across multiple substrates.
