GARANT NC Spotting Drill (5 mm)
High-Precision HSS-E TiAlN Coated Spotting Tool
Precision Engineering
The GARANT NC Spotting Drill is a professional-grade tool designed for high-accuracy center hole initiation. Featuring a 90° point angle and precision-centered point grinding with a thin chisel edge, it ensures effortless spot drilling. Its short flute design provides superior rigidity, minimizing deflection to maintain precise hole positioning.
Key Technical Highlights
- • Material: High-performance HSS-E with TiAlN coating for enhanced heat resistance.
- • Design: 2-flute, short construction for high stability.
- • Accuracy: h6 shank and nominal diameter tolerance.
- • Shank: DIN 1835 B (h6) for precise clamping.
| Nominal Ø (Dc) | 5 mm |
| Overall Length (L) | 120 mm |
| Flute Length (Lc) | 15 mm |
| Coating | TiAlN |
Operational Guidance
For optimal performance in steels up to 900 N/mm², utilize a feed rate of 0.04 mm/rev. Note: When calculating speeds, always use the parameters appropriate for the diameter of the actual hole being initiated, rather than the outer diameter of the spotting drill itself.
