Engineered for precision machining of non-ferrous metals and soft steels, our multi-step drill bit combines ultra-fine carbide substrate with customizable coating options to deliver exceptional tool life and versatility. Ideal for CNC machining centers, it performs drilling, chamfering, and countersinking in a single operation, significantly reducing production time.

• Advanced Material Options: Uncoated carbide optimized for aluminum, copper, and brass (prevents material adhesion) or AlTiN/TiN coated for extended life in abrasive soft steels (HRC<35)
• Multi-Step Geometry: Integrated diameter transitions (customizable step increments: 0.5mm/1mm/2mm) with precision ground edges (±0.02mm tolerance) for burr-free finishes
• Optimized Cutting Design: 3-4 flute spiral design (30°-45° helix) for efficient chip evacuation with 140° point angle to reduce thrust force in soft materials
• Coolant Compatibility: Through-tool coolant holes (2-4 channels, Ø1.0-1.5mm) supporting MQL and flood cooling for heat-sensitive alloys
• Rigid Carbide Construction: Sub-micron grain structure (K10/K20 grade) with Weldon flat shank option for heavy-duty machining

• Electronics Manufacturing: Heat sink holes + chamfers (Aluminum 6061), brass connector plates
• Automotive: Lightweight alloy housings (Mg/Al), soft steel brackets (HRC<30)
• General Machining: Multi-diameter holes in copper pipes, step drilling in plastic composites

• Advanced Equipment: WALTER and SAACKE brand grinding machines
• Precision Inspection: ZOLLER, OMEGA, PG1000 inspection systems
• Responsive Service: 24-hour online support
• Quality Assurance: Three-stage inspection process (raw material, semi-finished, final pre-shipment)
