Introduction:
5D through-coolant carbide drill bits are high-performance cutting
tools designed for deep-hole drilling (5x diameter depth) in tough
materials like stainless steel 304 and 316L on CNC machines. These drills feature internal coolant channels for
efficient chip evacuation, heat dissipation, and extended tool
life.
Features:
1. Material: Made from micro-grain carbide for hardness and wear resistance.
2. Geometry: Optimized point angle (140°) and helix angle for stainless steel,
reducing work hardening.
3. Through-Coolant Design: High-pressure coolant flows directly to the cutting edge,
improving chip removal and reducing heat buildup.
4. 5D Length: Suitable for deep holes (5x drill diameter) without frequent
retraction.
5. Coating: Often TiAlN or AlCrN for heat resistance and lubricity in
stainless steel.
