#8 Step Drill Bit, 1/2" - 1" by 1/16"

Milwaukee 48-89-9208 — Step Drill Bit (#8)

The Milwaukee 48-89-9208 is a #8 step drill bit, designed for drilling large-diameter holes in sheet metal, plastic, and thin steel using a single stepped bit instead of multiple twist drills.

It’s the largest step bit in the Milwaukee 9200-series you’ve been working through.

Hole range

This bit typically covers:

• 1/2" up to 1" diameter
• In 1/16" step increments
• About 9 steps total

So one bit can replace a whole set of large drill bits.

Key Features

• JAM-FREE dual-flute design – smoother cutting, less grabbing in metal
• Rapid Strike tip – starts holes cleanly with less walking
• Black oxide coating – improves durability and reduces heat
• Laser-etched size markings – lets you stop at exact diameters while drilling
• 3-flat shank (Secure-Grip) – prevents slipping in the chuck
• Optimized for cordless drills at high speed

Best uses

• Electrical panel knockouts (large conduit holes)
• HVAC sheet metal work
• Fabrication in thin steel or aluminum
• Plastic enclosures and chassis work
• Enlarging existing holes cleanly

Important limitation

This is a sheet-metal tool, not a structural drill:

• Works best on thin materials
• Not meant for thick steel plate
• Not a replacement for twist bits in deep drilling

How it fits your Milwaukee lineup

Compared to what you’ve been listing:

• 48-89-28xx: standard twist bits (general drilling)
• 48-89-46xx: impact-rated SHOCKWAVE twist bits
• Silver & Deming: large structural holes in thick material
• 9204–9208: step bits for fast multi-size sheet metal holes

So the 9208 is the “big knockout hole” tool in your collection.
