Step Drillbit | Milwaukee 6-40,5MM

Step drills: ideal applications

• Suitable for drilling into ferrous and non-ferrous sheet metals, profiles, and pipes

• Effective on copper, brass, aluminum, stainless steel, and plastics

• Maximum material thickness: 4 mm

• For optimal tool life, we recommend using a coolant

Trades:

• Electrical: Perfect for drilling panels and cabinets for cable gland installations

• Plumbing/HVAC: Ideal for creating access holes for pipework and installations

• Metalworking/Fabrication: Versatile in creating various sizes and for hole enlargement

• Automotive: Great for making holes for cable installation, mobile phones, antennas, and redirecting electrical wiring

• Maintenance/Repair Operations: Suitable for multiple applications, sizes, and hole enlargements

Step drill advantages over conventional drill bits:

• One bit for multiple hole sizes, reducing the need to carry different bits

• Best choice for enlarging existing holes

• More durable than traditional twist drill bits, with a thicker core to resist breakage

• More precise with less walking—tip starts drilling on contact

• Creates clean, burr-free holes, minimizing reaming

• Drills plastic without causing splitting or cracking

All-in-One tool:

• Spot Drill, Drill, and Deburr in one smooth operation

• RAPID STRIKE TIP™ ensures an accurate start without walking and enables fast drilling without pre-drilling

Enhanced performance:

• Special tip and step geometry for jam-free drilling, reducing the risk of snags with high-speed cordless tools and preventing material deformation

• Optimized 2-flute, ground-sharpened edge geometry for faster, smoother cutting

• Made from custom-engineered steel with black oxide coating for 4x longer life

• Optimized for use with high-speed cordless drills

Additional features:

• Laser-engraved size markings for long-term visibility

• Relief-ground steps allow the drill to automatically deburr while drilling

• 3-flat secure grip prevents slippage in the chuck, ensuring maximum torque transmission

Specifications:

• Shank diameter: 10 mm

• Size range: 6 – 40.5 mm

• Number of steps: 17

• Overall length: 90 mm
