| Precision reamers are designed to slightly enlarge the size of a previously formed hole with a high degree of accuracy that leaves the sides smooth. Youll find the reamer tool you need here for a variety of applications and materials. |
CoroReamer 435 is a multi-application, versatile and high speed reamer, suitable for a wide range of materials. It gives you really close hole tolerances and high-quality surface finish thanks to internal coolant, the cutting edge geometry and extremely unequal spacing of the cutting edges.
Benefits
- High productivity due to high cutting parameters
- Consistency and productivity saving time and costs
- Excellent surface finish on the component
- Uniform concentricity for long tool life and dimensional accuracy
- High stability due to the solid carbide body
- Internal coolant for better chip evacuation and reduced wear
Features
- Micro-grained carbide for high hardness and toughness
- Internal coolant (axial for straight flute and lateral for spiral flute) deliver coolant directly to the cutting zone, resulting in longer tool life and good chip evacuation
- DIN 65535 HA shank to H6 tolerance and for direct clamping in hydraulic chucks, such as CoroChuc 930, shrink-fit and high precision chucks
- Available as bright finish and TiAIN coating which allows an increase in cutting parameters, resulting in increased productivity and reduced built-up edge
- Flute geometry with extremely unequal flute spacing
Application
- For a wide range of applications and materials
- For all industry segments e.g. general machining, die and mould, automotive, energy and power generation
- Available in spiral flute for through holes and straight flute for blind holes
- Standard diameter range: 3.9720 mm (0.156-0.787 inch)
- Achievable hole tolerance: IT7
| Spiral flute | Straight flute -
For blind holes -
No chip flow -
Bigger chip angle -
Reduced vibration |
Comparison of unequal and extremely unequal flute spacing
Extremely unequal flute spacing means that the divide is not the same for each tooth. As there are no teeth diametrically opposite each other, the reamer produces a hole with improved hole roundness variance.
