4 Flute PCD Reamer Polycrystalline Diamond Precision Hole Finishing Tool For Aluminum Copper Composites

Introduction:

Our 4-flute PCD reamer represents the pinnacle of precision hole finishing technology. Engineered with medical-grade polycrystalline diamond (PCD) cutting edges and aerospace-balanced tool geometry, this reamer delivers mirror-like surface finishes (Ra 0.1-0.4μm) and exceptional dimensional accuracy in non-ferrous materials. Designed for high-volume production environments, it provides 50-100x longer tool life compared to carbide tools while maintaining consistent quality through thousands of holes.

Features:

✔ Premium PCD Construction

• 2-25μm diamond particle size (DA100/DA150 grades available)

• 0.3mm thick diamond layer brazed to carbide body

✔ Optimized 4-Flute Design

• 90° lead angle for optimal chip evacuation

• Polished flutes prevent material buildup

• Balanced to G1.0 at operating speeds

✔ Precision Performance

• H6-H8 tolerance capability (ISO 286)

• ±0.002mm diameter consistency

• 0.005mm/100mm straightness

✔ Material-Specific Engineering

• Aluminum version: 10° positive rake + nano-polish

• Copper version: Special edge prep for BUE prevention

• Composite version: Reinforced cutting edges

Advantages:

▶ 300% Higher Feed Rates vs carbide reamers

▶ 50,000+ Hole Life documented in AlSi9Cu3

▶ Eliminates Secondary Operations - achieves final finish in one pass

▶ Maintains ±0.002mm for entire tool life

Applications:

Automotive Manufacturing

• Engine block oil galleries (AlSi12)

• Transmission valve body bores

Aerospace Components

• Hydraulic fitting holes (7075-T6)

• Composite wing attachment points

Electronics Cooling

• Heat sink mounting holes (C11000 copper)
