<p>【High Hardness and Durability】 These unit reamers are made of high-speed steel, giving them high hardness and durability. <p>【Versatile Use】 Suitable for drilling holes in mold making and crafts. Widely used for drilling holes, installed in drills and milling machines, etc. Can be used to machine soft materials such as iron, wood, copper, and aluminum. <p>[Function] The reamer is used to ream the workpiece into the hole, primarily to improve hole accuracy and reduce surface imperfections. <p>【High Precision and Long Service Life】 The reamer on this machine uses a cutting edge, which has a high cutting capacity, high precision, and a long service life. <p>【Size】 Cutting edge diameter: 12 mm Cutting edge length: 66 mm. Total length: 102 mm <p>Description: <p>Reamers are mainly used for all types of drilled parts to improve drilling accuracy and reduce surface roughness. The number of blades on the reamer cuts and removes material from the surface of the hole into which the thin metal has been machined. After developing a reamer, the size and shape of the resulting holes can be precisely controlled. <p>Features: <p>These reamers are made of high-speed steel with high hardness and strength. The cutting edge is sharp, the cutting capacity is high, the accuracy is high, and the service life is long. Suitable for boring and crafting. <p>Widely used for drilling, mounted on drills, boring machines, etc. Finished surfaces of materials such as iron, wood, copper, and aluminum. <p>Technical Specifications: <p>Material: High-speed steel <p>Type: MT1 <p>Hole Shape: Conical <p>Precision Reamer: H7 <p>Burst: Fine and coarse <p>Needle Diameter: 12.065 mm <p>Needle Length: 66 mm <p>Total Length: 102 mm <p>Weight: 102 g (approx.) <p>Package Included: <p>2 Reamers <p>Size may vary by 1-3 cm due to manual measurement. <p>Color may vary slightly due to lighting and screen settings.
