Milwaukee 25/32″ S&D Black Oxide Drill Bit

INDUSTRIAL-GRADE BORING WITH REINFORCED THUNDERBOLT DURABILITY

The Milwaukee 48-89-2747 25/32″ Silver & Deming bit is engineered for high-torque applications where standard bits fail. Featuring the proprietary Thunderbolt core, this bit is designed with a thicker web to provide maximum strength and protection against side-load breakage, making it an essential asset for drilling into high-tensile materials like stainless steel and cast iron. The 1/2″ reduced shank allows you to run large-diameter holes using standard 1/2″ drill chucks, while the 3-flat Secure-Grip design ensures that every ounce of torque from your M18 FUEL power tools is transferred directly to the workpiece without the bit spinning in the chuck.

• / Thunderbolt Core technology provides a thicker web for increased durability and resistance to side-load snapping.
• / 135 Split Point Tip starts on contact to eliminate bit walking, ensuring precise hole placement in hard metals.
• / Parabolic Flute Geometry clears chips and debris rapidly to reduce heat buildup and extend the service life of the cutting edge.
• / 3-Flat Secure-Grip Shank prevents the bit from slipping in the chuck during high-load drilling operations.
• / Black Oxide Coating offers superior lubricity and corrosion resistance for consistent performance in harsh jobsite environments.
