Reamers

​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.

• 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

• 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

• 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: 3.97–20 mm (0.156-0.787 inch)
• Achievable hole tolerance: IT7

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.
