OHNS Shaft Drilling Jig, For Industrial

A Drill Jig is a precision tool used in manufacturing and metalworking to guide the drill bit accurately while drilling holes in a workpiece. It ensures repeatability, accuracy, and speed during the drilling process — especially for mass production.

🧰 Purpose of a Drill Jig:

• To locate and guide the drill to a specific position on a workpiece.

• Ensures hole accuracy (location, angle, and depth).

• Helps maintain consistency across multiple parts.

🏗️ Key Components:

1. Jig Body:

   • The base structure that holds all components.

2. Bushings:

   • Hardened steel sleeves that guide the drill bit precisely.

3. Locators/Clamps:

   • Secure the workpiece in the correct position.

4. Stops/Plates:

   • Control drill depth or limit movement.

🔧 Types of Drill Jigs:

1. Template Jig:

   • Simplest form with drill bushings mounted on a plate.

2. Plate Jig:

   • Flat plate jig with clamping devices; used for flat workpieces.

3. Channel Jig:

   • U-shaped body that wraps around the workpiece.

4. Box Jig (Enclosed Jig):

   • Encloses the workpiece from multiple sides, allows for multi-directional drilling.

5. Universal Jig:

   • Adjustable jig that can be used for different components.

6. Indexing Jig:

   • Used to drill multiple holes in circular parts with indexed rotation.

📦 Applications:

• Drilling multiple, identical holes in metal, plastic, or wood components.

• Aerospace, automotive, and general manufacturing industries.

• Ideal for batch production or when CNC is not cost-effective
