Milwaukee Milwaukee 48-89-9201 Step Drill Bit, 1/8 - 1/2 In., 13 Steps

This Milwaukee step drill bit drills multiple hole sizes in a single tool, handling metal and plastic applications efficiently. The stepped design with 13 increments in 1/32 in. intervals provides the hole diameters you need without switching bits.

The laser-engraved reference marks let you stop at the exact size needed without guesswork, while the rapid strike tip starts cleanly and reduces heat during operation. The black oxide finish prevents corrosion and works well with drilling lubricants for better performance.

Features and Benefits

• 2-Flute Design: Provides greater speed and control with jam-free performance, delivering up to 2 times faster drilling compared to standard bits.
• Rapid Strike Tip: Creates fast, accurate starts and generates less heat.
• Black Oxide Coating: Resists corrosion and has excellent capacity to work with drilling lubricants for improved performance and durability.
• Laser-Engraved Markings: Reference marks on the bit body let you stop at any desired hole size without measuring or calculation.
• 1/4 In. Hex Shank: Three-flat secure-grip design reduces bit slippage in the chuck and enables fast changes in impact drivers.
• High-Speed Steel Construction: Durable material designed to drill through most metals.
