Straight Flute Tungsten Steel CNC Machine Reamer for Automotive Aerospace Mold Making
Bullet Points
Precision Engineering:End-cutting angle design significantly enhances tool life and prevents chatter.
Premium Coating :Advanced coating technologies reduce tool wear and improve hole quality.
Durable Construction: Solid carbide body provides exceptional wear resistance in demanding applications.
Optimized Chip Evacuation :Straight flutes prevent chip clogging, reduce heat buildup.
Versatile Compatibility :Works with CNC machines, drill presses and lathes.
Applications
Automotive Manufacturing:Precision reaming of engine blocks, transmission parts, brake systems, cylinder bores and gear shafts.
Aerospace:Hole finishing on turbine shafts, turbine blades and landing gear at aerospace-grade tolerances.
Mold & Die Making:Reaming of guide-pin and ejector holes for precise mold assembly.
General Metalworking:Finishing holes in hydraulic cylinders, bearings and general industrial machinery.
Hardened Material Machining:The carbide version reams hardened steels (HRC 45+) for post-heat-treatment finishing.
Hot Q&A
- What is the difference between a machine reamer and a hand reamer?
Answer: Machine reamers are designed for use with CNC machines, lathes and drill presses, offering higher speed and accuracy; hand reamers are manually operated for light-duty, low-volume work.
- What speed and feed should be used for stainless steel?
Answer: For HSS reamers use 10–15 SFM and 0.002–0.004 inch per revolution; carbide allows higher speeds. Use adequate coolant and steady feed.
- How can premature wear be prevented?
Answer: Use adequate coolant, avoid excessive RPM, keep the pre-drilled hole at 90%–95% of the final diameter, and avoid excessive feed.
- Straight flute or spiral flute — which to choose?
Answer: Straight flutes reduce edge chipping on brittle materials such as cast iron and suit through holes; spiral flutes fit ductile metals and blind holes.
