Cone & Step Drill Bits

Cone and step drill bits are essential for sheet metal, thin plastics, and light gauge work. These bits let you drill multiple hole sizes with a single tool, ideal for HVAC installations, electrical boxes, and panel work. Their design ensures a clean cut and prevents material tearing, making them a staple for electricians, plumbers, and metalworkers.

What Are Cone & Step Drill Bits Used For?

• Electrical Installations Perfect for creating knockouts in electrical panels and enclosures without changing bits.
• HVAC Work Ideal for cutting through sheet metal ducts and vents, providing a clean finish with minimal effort.
• Plumbing Jobs Used for drilling holes in sink and pipe fittings, ensuring a precise fit for connections.
• Sheet Metal Fabrication Allows quick and accurate hole sizing in thin metals, avoiding tearing or deformation.

Who Uses Cone & Step Drill Bits?

• Electricians needing to make various hole sizes in panels without swapping bits.
• HVAC technicians who require clean, burr-free holes in ductwork.
• Plumbers fitting sinks and pipework where precision is key.
• Metal fabricators who need versatile tools for thin gauge materials.

Choosing the Right Cone & Step Drill Bit

Select the right bit based on your material and hole size requirements:

1. Material Compatibility

Ensure the bit is designed for the material you're working with-most are suited for metal and plastic, but check for specific coatings that enhance durability.

2. Step Size Range

Choose a bit with a step size range that matches your task, whether it's small adjustments or larger holes up to 35mm.

3. Shank Type

Opt for a bit with a shank that fits your drill-3-flat shanks prevent slipping in the chuck, ensuring a steady cut.
