Solid Carbide Multi-Step Drill Bit for Aluminum Copper Soft Steel Uncoated Coated Options
Introduction:
Features:
✔ Advanced Material Options
Uncoated Carbide: Optimized for aluminum, copper, and brass (prevents material adhesion)
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)
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
140° point angle reduces thrust force in soft materials
✔ Coolant Compatibility
Through-tool coolant holes (2-4 channels, Ø1.0-1.5mm)
Supports MQL and flood cooling for heat-sensitive alloys
✔ Rigid Carbide Construction
Sub-micron grain structure (K10/K20 grade)
Weldon flat shank option for heavy-duty machining
40% Faster Machining vs. standard twist drills (combined operations)
2-3× Longer Tool Life with AlTiN coating in abrasive materials
Mirror Finishes (Ra ≤0.8µm) achievable in aluminum/copper
