Descriptions: Adjustable hand reamer is designed to accurately enlarge, smooth or finish holes in stainless steel, cast iron, aluminum, non-ferrous metals, plastic, and wood, widely used in hole repair work, pipe and fittings, woodworking applications.
Straight flute reamer allows chips and debris to escape easily from the hole, well suited for most applications in shallow cuts. Can achieve the required roundness, straightness, and concentricity of the hole.
Reaming tool set is made of 9SiCr alloy steel, which has excellent hardness, toughness and wear resistance, suitable for cutting ferrous and non-ferrous metals. Features just the base substrate (no additional coating), suitable a wide range of materials.
Reamer drill bit can be hand operated by use of a wrench, T-handle wrench, extension rod, drill chuck. Used for light cut, repair work, removing stock or simply for enlarging holes. Cutting fluid or lubricant can be used to lubricate the reamer and workpiece to help reduce friction, improve surface finish and increase tool life.
Tips: Pay attention to the chips generated during the reaming process. If chips begin to clog the reamer's chip flutes, cutting performance will be affected. Make sure the workpiece is securely clamped or held in place to minimize movement.
