Milwaukee #4 Step Drill Bit, 3/16" - 7/8" by 1/16"

RAPID PENETRATION PERFORMANCE

Milwaukee's engineering team has redefined the standard for step bits, focusing on the two metrics that drive jobsite efficiency: speed of execution and thermal management. The 48-89-9204 bit is purpose-built for the modern cordless ecosystem, featuring a dual-flute geometry that reduces the torque required per hole. This design not only accelerates the cut but significantly extends the runtime of your batteries, ensuring that high-volume layout work doesn't stall out. By utilizing a black oxide finish and a specialized rapid-strike tip, Milwaukee delivers a bit that starts on contact and resists the corrosive wear common in industrial environments.

• / JAM-FREE GEOMETRY: The dual-flute design is optimized for high-speed cordless operation, providing superior debris clearance and preventing bit lock-up in thin metals.
• / RAPID STRIKE TIP: Engineered for precise starts without the need for a center punch, reducing bit walking and heat generation during the initial penetration.
• / PERMANENT REFERENCE MARKS: Laser-etched size markings provide high-contrast visibility for the life of the bit, ensuring accurate hole sizing in any conditions.
• / BLACK OXIDE TREATMENT: Superior surface coating prevents corrosion and retains drilling lubricants more effectively than untreated high-speed steel.
• / 3-FLAT SECURE-GRIP: Specifically designed to eliminate slippage in standard 3-jaw chucks, maximizing torque transfer for smoother, faster drilling.
