Greenlee Professional Step Bit Kit with Steam Oxide Finish - 1/8" to 1-1/8" Multi-Hole Drilling System

Greenlee Professional Step Bit Kit with Steam Oxide Finish

Professional multi-hole drilling solution for steel and sheet metal applications

The Greenlee Professional Step Bit Kit delivers reliable performance for drilling multiple hole sizes in steel and sheet metal applications. This comprehensive kit features steam oxide finish technology that runs cooler for extended tool life, while the unique split-tip design penetrates steel faster than conventional bits. Designed for professional use with maximum sheet metal thickness capability up to 10 gauge (3.5mm) and drilling capacity from 1/8" to 1-1/8" diameter.

Professional Features & Benefits

• Steam Oxide Finish: Advanced coating runs cooler during operation, significantly extending bit life and reducing replacement costs in demanding applications.
• Unique Split-Tip Design: Engineered tip configuration penetrates steel faster, improving drilling efficiency and reducing operator fatigue.
• Multi-Hole Capability: Single bit design eliminates the need for multiple drill bits, streamlining workflow and reducing tool inventory requirements.
• 1/8" to 1-1/8" Range: Comprehensive size range covers most common hole drilling requirements in professional electrical and mechanical applications.
• 10 Gauge Sheet Metal Rating: Handles thick sheet metal up to 3.5mm, suitable for heavy-duty electrical enclosures and industrial applications.
• Complete Kit Solution: Includes three essential Kwik Stepper Bits (34401, 34403, 34408) for immediate productivity across multiple hole sizes.

Technical Specifications

• Included: 34401, 34403 and 34408 Kwik Stepper Bits
• Maximum Drill Diameter: 1-1/8 In
• Maximum Sheet Metal Thickness: 10 gauge (3.5mm)
• Minimum Drill Diameter: 1/8 In

Installation & Operation

1. Mount the step bit securely in a compatible drill chuck, ensuring proper alignment and tight grip.
2. Mark the desired hole location and center punch for accurate drilling start point.
3. Begin drilling at low speed to establish the pilot hole, then increase speed as the bit engages the material.
4. Apply steady, consistent pressure while allowing the step design to gradually enlarge the hole to the desired diameter.
5. Monitor bit temperature and allow cooling periods during extended use to maximize steam oxide finish benefits.
6. Clean bits after use and store in the kit case to maintain cutting edge sharpness and organization.

Professional Applications

• Electrical panel and enclosure installation
• HVAC ductwork and sheet metal fabrication
• Industrial maintenance and repair operations
• Commercial construction and retrofit projects
• Automotive and transportation equipment service
