FEATURES
Step drill bits are ideal for drilling in the following materials: Ferrous and non-ferrous metal sheets, profiles, tubes, copper, bronze, aluminum, stainless steel, and plastics. Up to 4mm thick. For greater durability, we recommend working with coolant

Users: Electricians: drilling in junction boxes, panels, etc., for cable passage and installation. Plumbers and HVAC: access holes for pipe installation. Metalworkers: enlarging or varying hole diameters. Automotive: holes for telephone wiring, antenna, or cable passage. Maintenance and repair: hole enlargement

Advantages of step drill bits vs. conventional drill bits: One drill bit with multiple diameters – Carry more in less! The best option for enlarging existing holes. Longer lasting than a drill bit, thanks to its more reinforced shaft. More precise and with less “skidding” effect – Drills just by touching the material. Cleaner holes without burrs. Drills plastic without breaking or chipping it

MILWAUKEE® Advantages

Centering tip – drill bit – reamer – all in one

Quick centering tip – prevents skidding and drills quickly without needing to mark the piece with a punch or pre-drill

Special tip and special step design, to prevent jams – lower risk of jams or hits when used with tools, avoiding deforming the piece

2 cutting edges, for faster and smoother drilling

Made of steel alloy, oxide-coated to offer 4 times more durability

Designed to work with battery-powered machines

Laser-marked measurements, for better visibility over time

Each step is designed to drill and ream in one pass

3-sided shaft for better grip, preventing slipping in the chuck. Improves power and torque transfer to the drill bit
