Milwaukee 48-89-9205 #5 Step Drill Bit, 1/4" - 1-3/8" by 1/8" Step Increments

Milwaukee 48-89-9205 #5 Step Drill Bit, 1/4" - 1-3/8" by 1/8" Step Increments

The Milwaukee 48-89-9205 #5 Step Drill Bit is engineered to bore clean, precise round holes across a wide range of diameters using a single tool. This step bit covers a cutting range of 1/4" up to 1-3/8", advancing in graduated 1/8" increments so technicians can move from one hole size to the next without swapping tools mid-job. The stepped design is well suited for enlarging knockouts and punching holes in electrical enclosures, panels, junction boxes, and sheet metal where multiple hole diameters are required on the same workpiece. As Model #5 in the Milwaukee step bit lineup, this bit is built to deliver repeatable, accurate results for electricians, HVAC technicians, and metal fabricators working in the field or shop.

Key Features

• Step Range: Cuts a full range of hole sizes from 1/4" up to 1-3/8" with a single bit, reducing the number of individual drill bits needed on the job.
• 1/8" Step Increments: Graduated steps advance in 1/8" increments, giving installers precise, incremental control over final hole diameter as they drill.
• #5 Step Bit Configuration: Milwaukee's Model #5 step pattern is sized to cover common electrical, mechanical, and sheet metal hole-sizing requirements in one tool.
• Single-Tool Versatility: One step bit replaces an entire set of twist bits or hole saws when a job calls for multiple hole diameters on the same material.
• Milwaukee 48-89-9205: Identified by Milwaukee part number 48-89-9205 for straightforward reordering, inventory tracking, and cross-referencing.
• Stepped Cutting Edge: The progressive step geometry helps center the bit and start clean holes without walking, even on thin-gauge material.
