High-Performance Metal-Ceramic Reamers
At Wangdefu, we specialize in high-precision tooling and prototypes for automotive and robotics industries. Our High-Performance Metal-Ceramic Reamers combine the ultra-hard wear resistance of ceramic with the toughness of metal, delivering unmatched performance for precision hole finishing. Designed for carbon steel, stainless steel, mold steel, titanium, and other materials, these reamers achieve IT6-IT7 tolerance and mirror-like surface finish (Ra0.2-0.6μm). With Wangdefu reamers, manufacturers can achieve “reaming instead of grinding,” saving time while maintaining the highest quality standards in automotive, aerospace, and mold manufacturing.
Why choose WangDefu High-Performance Metal-Ceramic Reamers?
Tough & Wear-Resistant Composite Material
Made from TiC/TiN ceramic phases bonded with Ni-Co metal, sintered under high-temperature powder metallurgy.
Hardness up to HRA93, 30% more wear-resistant than conventional carbide, with bend strength ≥3200MPa.
Ideal for interrupted holes, angled holes, and long overhang conditions, maintaining hole straightness <0.01mm/100mm.
Low Affinity & Coating-Free Cutting
Extremely low chemical affinity with ferrous metals, friction coefficient ~0.1.
Prevents sticking and built-up edge when machining stainless steel or titanium.
Can be re-sharpened repeatedly without losing precision, extending tool life 3-5x longer than standard carbide reamers.
Precision Geometry & Optimized Flutes
Five-axis precision ground cutting edges, edge radius ≤0.003mm.
6–12 blades evenly spaced, reducing vibration by 50%.
Supports straight flutes (through holes) and spiral flutes (15°–30°, blind/deep holes).
Maximum deep-hole ratio L/D up to 8D without clogging.
High-Temperature Stability & High-Speed Cutting
Retains hardness and strength up to 1000°C, ideal for high-speed operations.
Optional high-pressure internal coolant (20–30MPa) for precision cooling and chip removal.
Speeds 20–50% higher than traditional carbide reamers, especially for hardened steel and superalloys.

Applications
Automotive Manufacturing:
Reaming precision bolt holes in stainless steel gearbox housings. For example: φ10mm 8-flute helical reamer, cutting speed 70m/min, feed rate 0.2mm/r, tolerance ±0.004mm, surface roughness Ra0.4μm.
Aerospace Components:
Titanium alloy landing gear bushing holes. The cermet material prevents work hardening; High-Performance Metal-Ceramic Reamers have a life exceeding 600 holes, four times that of standard carbide tools, increasing productivity by 30%.
Mold Industry:
SKD11 hardened steel guide post holes. A straight-edged 10-flute reamer completes the hole machining in one pass, with a coaxiality of 0.005mm, eliminating the need for subsequent polishing and reducing the machining cycle time by 50%.
