Milwaukee 19/64" Thunderbolt Black Oxide Drill Bit 48-89-2719

ENGINEERED FOR EXTREME DURABILITY IN HIGH-STRESS DRILLING

The Milwaukee 48-89-2719 isn't just another jobber bit; it is a precision-engineered solution for high-torque applications where standard bits frequently fail. By utilizing the Thunderbolt® web—a significantly thicker core than standard bits—this 19/64" bit absorbs the lateral forces that typically cause breakage during deep-hole drilling or when the drill binds. The black oxide coating provides critical lubricity to reduce heat buildup, which is the primary enemy of edge retention when working through carbon and alloy steels. Designed for the professional who demands long-term ROI, this bit features a parabolic flute geometry that clears chips rapidly, ensuring the cutting edge stays cool and efficient during repetitive drilling cycles.

• / 135° Split Point Tip starts on contact to eliminate walking and ensure immediate penetration without the need for a center punch.
• / Thunderbolt® Web Technology features a thicker core to protect against side-load breakage and provide ultimate strength in portable drilling applications.
• / Parabolic Flute Design maximizes chip ejection and airflow to keep the bit cool, extending the life of the cutting edge.
• / Black Oxide Coating resists corrosion and provides a slick surface that prevents material buildup on the flutes.
• / 3-Flat Secure-Grip Shank prevents the bit from spinning in the chuck under high-torque loads (on sizes 3/16" and larger).
