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:


1. Specialized Tool Geometry

  • 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


2. Advanced Material Technology

  • 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


3. Documented Performance Advantages

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


4. Customization Options

  • 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



Applications:


Medical Device Manufacturing

  • Surgical instrument precision holes

  • Implant component through-holes


Food Processing Equipment

  • Valve body machining

  • Mixing shaft bearing seats


Marine & Chemical Systems

  • Pump housing bores

  • Heat exchanger tube plates


General Precision Engineering

  • Hydraulic component finishing

  • Bearing housing precision bores
