Usage
The Milwaukee Step Drill M6–M32 is designed for precise drilling of 13 variable hole sizes in metal sheets, profiles, pipes, and plastics. It’s suitable for industrial, installation, and maintenance tasks requiring multiple diameters.
Advantages
- One drill bit covers a wide hole range from 6.5 mm to 32.5 mm
- JAM-FREE dual-flute design delivers up to 2X faster drilling and improved control
- Black oxide coating extends lifespan up to four times compared to standard bits
- Laser-engraved size markings ensure easy identification while drilling
- The use of a coolant is recommended for optimal tool life when working with thick metals[1][2][4]
Specifications
- Cutter Geometry: Dual-flute step design made from custom steel with black oxide coating for enhanced durability[1][4]
- Lifespan: Up to four times longer life than conventional bits; optimized geometry cuts faster and reduces heat[1][3]
- Performance: Drills holes ranging from M6 (6.5 mm) to M32 (32.5 mm) in increments; suitable for material thicknesses up to approximately 4 mm; supports jam-free high-speed drilling on cordless drills[1][2][4]
- Differentiators: Rapid Strike tip ensures fast starts without pre-drilling; laser-engraved steps aid accuracy; Secure-Grip three-flat shank prevents slipping in drill chucks[1][3][4]
How it works
Select the required hole diameter by aligning the desired step marking with the surface before starting. The Rapid Strike tip initiates accurate drilling with minimal heat buildup, while each step enlarges the opening as needed with one tool change.
