10-Piece Hand Reamer Set (3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm) H7 Metric Straight Flute Alloy Steel Reamer, Steel Cutting Tool for Metal and Wood

Hand Reamer Size: Cutting Diameter: 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm; Tolerance: H7. Hand reamers ream cylindrical shapes. Good for general applications.

Wide Applications: The reamer is designed to accurately enlarge, smooth, or finish holes and is suitable for precise reaming in stainless steel, aluminum, copper, alloy, plastic, and wood. Widely used in hole repair work, pipes, fittings, and woodworking applications.

Straight Flutes: Allow chips to collect in the flutes, ideal for most shallow-cut applications. Can achieve the required roundness, straightness, and concentricity of the hole.

A cutting fluid or lubricant can be used to lubricate the reamer and the workpiece to reduce friction, improve surface finish, and increase tool life. 9SiCr Alloy Steel: The hand reamer is made of 9SiCr alloy steel, which offers excellent hardness, strength, and wear resistance, suitable for cutting various materials, including ferrous and non-ferrous metals. With just a basic substrate, it is suitable for a wide range of applications. Tips: The reamer bit can be easily operated manually with a wrench, T-handle, extension rod, or drill chuck. Use it for light cutting, repair work, material removal, or simply enlarging holes. Be careful of the chips generated during the reaming process. If chips begin to clog the reamer's chip grooves, cutting performance will be affected.
