Premium Carbide Step Drill Bit with AlTiN Coating

Engineered for extreme performance in hard metal machining, this carbide step drill bit features wear-resistant AlTiN coating, high-efficiency spiral flutes, and precision internal coolant channels for challenging drilling applications.

Key Features

Advanced AlTiN Coating: Withstands temperatures up to 800°C with superior abrasion resistance for extended tool life, ideal for dry or semi-dry machining conditions
Optimized Spiral Flute Design: 30°-45° helix angle for improved chip evacuation, reduced cutting forces, and smoother surface finishes
Internal Coolant System: 2-4 coolant holes (Ø1.0-1.5mm) direct lubricant to cutting edges, enabling higher feed rates and deeper hole drilling
Solid Micro-Grain Carbide Substrate: Sub-micron carbide grain structure maintains edge integrity in materials up to HRC 65 with 3-5× longer lifespan than HSS tools
Multi-Step Geometry: Eliminates tool changes for tapered holes, countersinking, and deburring with ±0.02mm dimensional accuracy
