This paper investigates the specific energy and the chip load of a thread making process called thrilling, which performs both drilling and thread milling with one tool. A chip thickness and cutting force models have been used for a drilling operation with a thrilling tool. The models consider a complex geometry of a thrilling tool and the unique tool paths associated with the drilling operation and thread milling operation with a thrilling tool. Calibration experiments have been conducted to estimate the cutting coefficients associated with specific cutting energies and the relation between the specific cutting energies of both operations has been compared.
