Milwaukee 25/32" Thunderbolt Black Oxide Silver & Deming Drill Bit 48-89-2747
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.
