The Portable 90° Precision Drilling Machine with Multi-Position Depth Control Mechanism is an innovative Mechanical Engineering CAD project developed by DOT Institute, Trichy using PTC Creo Parametric. This project demonstrates advanced mechanical design, precision engineering, and professional CAD modeling skills required in today’s manufacturing and industrial sectors.
Designed by Mechanical Engineering student Guruprasath, this project focuses on improving drilling accuracy in confined workspaces where conventional drilling machines cannot operate efficiently. The design integrates a 90-degree drilling mechanism with a multi-position depth control system, making it suitable for precision drilling applications in automotive, aerospace, fabrication, machine maintenance, and industrial manufacturing.
This project showcases the practical application of PTC Creo Parametric in product design, assembly modeling, component design, engineering drafting, and real-world mechanical problem-solving.

The Portable 90° Precision Drilling Machine is developed to provide accurate drilling performance in difficult-to-reach locations while maintaining operator comfort and drilling precision.
The integrated multi-position depth adjustment mechanism enables users to control drilling depth accurately, reducing material damage and improving production quality.
The complete model was created using PTC Creo Parametric, including:
Designed for accurate right-angle drilling applications where standard drilling machines cannot reach.
Provides adjustable drilling depth for various industrial requirements.
Lightweight mechanical structure suitable for maintenance and field operations.
Complete assembly designed using industry-standard CAD techniques in PTC Creo.
Engineered for precision, stability, and reliable performance.
Designed with practical industrial applications and manufacturability in mind.
