Description:Machinereamer is used to ream workpieces that have been drilling hole, mainly to improve the precision of hole and reduce its surface roughness. With many blades, machine reamer cuts and removes the thin layer metal on hole surface that has been processed. After the processing of a reamer, machining hole size and shape can be precise.Features:Made of high speed steel, these reamers have high hardness and durability.Sharp cutting-edge, high cutting ability, high accuracy, long service life.Applicable for reaming to mould processing and handicraft processing.Widely used for bore machining, installed in drilling machine, milling machine, etc.Processed surface of iron, plastic, wood, copper, aluminum and other soft materials.Specifications:Material: High Speed SteelType: MT2Reaming Shape: coneReamer Precision: H7Cutting Edge: Fine and roughSize: 1.5*12.5cm/0.6*4.9inQuantity: 2Weight: 258g(approx.)Packaging Includes:2pcs x Reamers
