Industrial manufacturing and assembly tasks
Mechanical repairs and maintenance
Countersinking and hole enlargement in sheet metal
When it may not be suitable
This step drill bit is not designed for drilling in dense masonry, concrete, or structural stone. It may also prove unsuitable for very thick solid metals where standard twist drills of a fixed diameter are required for deeper penetration.
Key specifications
Tool type: Step drill bit
Material: High-speed steel (HSS)
Maximum diameter: 18.5 mm
Application material: Metal
How to use
Begin by securing the workpiece firmly to prevent movement during operation. Center punch the desired spot to guide the drill tip accurately. Insert the step drill bit securely into the drill chuck and start at a low to moderate speed with adequate cutting fluid to reduce heat buildup. Apply steady, moderate pressure, allowing the progressive steps to cut cleanly through the material until the 18.5 mm diameter is achieved.
What to consider before purchase
Verify that your power drill is compatible with standard shank sizes used for step drills.
Ensure the 18.5 mm maximum diameter matches your specific project requirements.
Confirm that the primary material you intend to drill is metal.
For optimal performance and extended tool life, always use appropriate cutting lubricants and operate the drill at recommended speeds suitable for high-speed steel tooling.
