4 Flute Coolant Through Step Drill for 304 316L Steel AlTiN Coated Carbide Reamer with Internal Cooling Channels
Introduction:
Our premium 4-flute coolant-through step reamer is specifically engineered for high-performance machining of austenitic stainless steels (304/316L). Featuring advanced AlTiN coating and optimized internal coolant channels, this carbide tool delivers superior hole quality and extended tool life in these notoriously gummy, work-hardening materials.
The unique step drill design combines drilling and reaming operations into one efficient process, significantly reducing cycle times while maintaining IT6-IT7 grade tolerances. Ideal for medical, food processing, and marine applications where 304/316L stainless steels' corrosion resistance is critical.
Features:
4-flute design with 35° helix angle for optimal chip evacuation
Polished flute surfaces prevent material adhesion in gummy steels
Step configuration enables combined roughing/finishing in one pass
Sub-micron tungsten carbide (0.5μm) for maximum edge stability
AlTiN nano-coating with enhanced lubricity for stainless steels
Through-tool coolant (2-4 ports) for effective heat management
✓ 4× longer life vs standard HSS reamers in 316L
✓ Ra 0.8μm surface finish achievable
✓ 30% higher feed rates through optimized chip breakers
✓ Eliminates built-up edge (BUE) common with stainless
Diameter range: 3-20mm (0.118"-0.787")
Step configurations: 2-3 steps per tool
Shank options: Straight, Weldon, hydraulic
Special features: Left-hand spiral, reduced neck
