Step drill

Product Description

Step drill is a specialized cutting tool used to drill holes of multiple diameters in a single operation. It has tapered and stepped levels, each corresponding to a specific hole diameter.

Our high-speed steel step drill bits are engineered to drill multiple hole sizes with a single tool. Perfect for thin materials like sheet metal, plastic, and PVC, they create perfectly smooth, round holes with a deburred edge in one swift operation. Save time and simplify your toolbox.

Key Features of a Step Drill

1. Tapered Design:

- The drill has a tapered body with multiple steps, each representing a different diameter.

- This design allows multiple hole sizes to be drilled with a single tool.

2. Material:

- Usually made of high-speed steel.

3. Flutes:

- Step drills typically have spiral flutes that help remove chips and debris during drilling.

- Some designs have straight flutes for specific applications.

Advantages of a Step Drill

- Efficiency: No need to switch between different drill bits.

- Clean Cuts: Produces smooth, burr-free holes, especially in thin materials.

Types of Step Drill

1. Standard Step Drill:

- General purpose step drill for metal, wood, and plastic.

2. Carbide Step Drill:

- Features a carbide tip for extreme hardness and wear resistance.

- Suitable for abrasives and high volume drilling.

3. Adjustable Step Drill:

- Allows the user to adjust the step size for greater flexibility.

How to Use a Step Drill Properly

1. Secure the workpiece (use clamps for metal/plastic).

2. Start at low speed (to prevent slipping).

3. Apply steady pressure (let the bit cut, don’t force it).

4. Use cutting oil (for metal to reduce heat & wear).

5. Stop at the desired step (don’t overshoot).
