Key Benefits

• Multi-size step drill design covers 6–38mm diameter range in one bit
• 12 stepped sizes reduce bit changes and improve drilling efficiency
• HSS 4341 material supports durable cutting performance
• Titanium finishing helps improve wear resistance and heat tolerance
• Round shank fitment for common drill chucks

Product Overview

Step drill bits are commonly used for drilling and enlarging holes in thin materials, especially sheet metal, aluminum sheets, and plastics. The stepped profile allows controlled progression through multiple diameters, helping reduce burrs and improving hole consistency when used with the correct speed and lubrication.

The TAC7563801 features a titanium finish over HSS 4341 for improved durability. Its round shank design makes it compatible with standard corded and cordless drills with appropriate chuck capacity.

Ideal Applications

• Drilling and enlarging holes in sheet metal
• Electrical panel work and enclosure fabrication
• Plumbing and installation tasks requiring multiple hole sizes
• Drilling on aluminum, mild steel sheets, and plastics (with proper technique)
