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.

Step drill is a highly efficient, multi-functional composite drill bit that integrates functions like drilling, enlarging holes, countersinking, and deburring through its unique stepped structure. Its advantages are particularly evident when machining thin sheet materials.

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).
