A 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.
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.
- Space Saving: Replaces multiple drill bits, reducing tool storage requirements.
Applications of Step Drill
Woodworking:
- Drilling holes in wood, plywood, and MDF.
- Ideal for projects that require a variety of hole sizes.
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.
