Internal Coolant Step Drill for Aluminum Carbide Multi Diameter Drill Bit with Coolant Holes
Introduction:
Features:
Internal Coolant Channels (Through-Tool Cooling)
2-4 precision coolant holes (Ø1.0-1.5mm) for direct lubrication
Reduces heat & prevents built-up edge (BUE) in sticky aluminum alloys
Multi-Diameter Step Design
Integrated diameter transitions (e.g., 6mm → 8mm → 10mm)
Eliminates tool changes for drilling + chamfering in one pass
Optimized for Aluminum
Polished flutes minimize chip adhesion
3-4 flute spiral design (30°-45° helix) for smooth chip evacuation
Solid Carbide Construction
Micro-grain carbide (K30/K40 grade) for wear resistance
Sub-micron grain structure ensures edge sharpness
High-Speed CNC Ready
Balanced geometry reduces vibration at 15,000+ RPM
h6 tolerance shank for precision collet/chuck mounting
40% Faster Machining – Combines drilling + chamfering operations
2X Longer Tool Life vs. HSS drills (no edge welding in aluminum)
Mirror Finishes (Ra ≤0.8µm) with polished flutes
No Chip Clogging – Coolant + spiral flutes clear chips efficiently
Application:
Electronics
Heat sink mounting holes (6061/6063 aluminum)
PCB fixture plates
Automotive
Lightweight engine blocks (A380 die-cast aluminum)
Battery tray drilling
Aerospace
Aircraft structural components (7075-T6)
Drilling + chamfering in thin-wall parts
General Machining
