Helical Twist Drill Bit
The fundamental tool for hole-making in machining. This module examines point geometry, chip evacuation (flute) dynamics, and red-hardness (thermal stability) principles.
Visualizing complex assemblies in 3D reduces error rates during maintenance operations and accelerates the learning curve for new technicians.

Use Case
This structure is used for metallurgical training, CNC cutting tool optimization, machining methods, and coating technology (PVD/CVD) presentations.
Point Angle & Material Hardness
Explains why the standard 118° point angle is changed to 135° (split point) for harder materials and how this affects self-centering accuracy.
Chip Evacuation & Heat Management
Describes the speed of chip removal through flutes and the dynamics of coolant reaching the cutting tip.
Coating & Tool Life
Highlights how TiN or TiAlN coatings increase surface hardness to 2500+ HV and significantly reduce the coefficient of friction.
Helical Twist Drill Bit - Detailed Specifications
Below is the comprehensive engineering breakdown of each component within the assembly. This data includes standard material selections, ISO tolerances, surface finishes, and critical engineering notes required for manufacturing and assembly.
HSS-Co Drill Bit
Cutting Tool / Consumable
A precision cutting tool with two main cutting edges and two helical flutes for chip evacuation, designed to create circular holes.
Performance is dictated by "Point Geometry." Web thinning reduces thrust force, allowing easier penetration. The addition of 5-8% Cobalt (Co) ensures the material maintains its hardness even at temperatures above 600°C (red-hardness), enabling the drilling of tough materials like stainless steel.
