Product Overview

Step drill bits are commonly used for creating and enlarging holes in sheet materials, especially where multiple sizes are required on the same job. The Total TAC8242201 provides a 4–22mm range, allowing users to drill pilot holes and expand to the required diameter using a single tool.

This bit is suitable for fabrication and installation tasks such as panel work, electrical box preparation, and general shop drilling where accurate diameter steps improve efficiency. Proper speed control, lubrication (for metal), and steady pressure help produce cleaner results and extend tool life.

Ideal Applications

• Hole drilling and enlargement on thin metal sheets
• Panel and enclosure work for fabrication and installation
• Plastic and laminate drilling (with appropriate speed and support)
• General workshop and maintenance drilling tasks
