#1 Step Drill Bit, 1/8" - 1/2" by 1/32"

Step Drill Bit, 1/8" – 1/2" by 1/32"

A step drill bit is designed to drill multiple hole sizes with a single bit. This model gradually enlarges holes from 1/8 inch up to 1/2 inch, increasing in 1/32-inch increments, making it ideal for precise hole sizing in thin materials.

Key Features

• Multiple Hole Sizes in One Bit: Drills sizes from 1/8" to 1/2" in 1/32" steps, eliminating the need for multiple drill bits.

• Step Design: Each step acts as a separate cutting diameter, allowing clean and accurate hole enlargement.

• Smooth, Burr-Free Holes: The stepped profile reduces tearing and leaves cleaner edges compared to standard twist bits.

• Ideal for Thin Materials: Works well with sheet metal, aluminum, brass, copper, plastic, and thin steel.

• Efficient Drilling: The progressive steps allow gradual cutting, reducing vibration and improving control.

Typical Applications

• Electrical panel and junction box holes

• Sheet metal fabrication

• Automotive body work

• HVAC duct installation

• Plastic and acrylic drilling

Specifications
