Description

Specifications: Cutting diameter: 4.5mm/0.177 inch; tool edge length: 19mm/0.75 inch; overall length: 75mm/2.95 inch. Tolerance grade: H7 High-Quality High-Speed Steel: Manufactured from high-speed steel (HSS), combining hardness and toughness. Features wear tolerance and effective debris breaking. Straight Flute Design: Concentrates debris at the cutting edge for efficient debris evacuation, reducing damage to the bore wall. Suitable for reaming shallow holes, ensuring hole roundness, straightness, and concentricity. H7 Tolerance Grade: Ensures consistent dimensional accuracy during reaming, meets standard fit requirements, and reduces rework caused by hole diameter deviations. Universal Material Compatibility: Suitable for common materials such as stainless steel, cast iron, aluminum, plastic, and wood. Can also be used for light cutting, deburring, repair, or reaming. Clamping Instructions: Shank diameters are specified in metric millimeters (mm), not imperial inches. Before use, ensure the collet securely grips the metric shank diameter. If using an imperial collet, it is recommended to install a reducer sleeve. Machining Notes: Provide 0.1–0.3 mm of clearance in the pilot hole; ensure coaxiality to the pilot hole (a floating collet is recommended); use low spindle speeds and moderate feed rates; coolant must be used—do not dry cut. Brand: DRINYOUNG Product type: chuck reamer Material: high speed steel Colour: silver, grey Reaming Type: Cylindrical Cylindrical Specification: 4.5mm Accuracy: H7 Cutting diameter: 4.5mm/0.177 inch Cutting straight slot length: 19mm/0.75 inch Overall length: 75mm/2.95 inches Packing list: 1 x Clamping reamer This H7 straight-shank reamer is manufactured from high-quality high-speed steel. Its straight flutes ensure smooth debris evacuation, resulting in holes featuring excellent roundness and consistent precision (H7 tolerance). It can be used for reaming, deburring, or finishing holes in materials such as cast iron, steel, aluminum alloy, and plastic. Please note: The shank diameter is specified in metric units (mm), not inches. Metric shank diameters may not fit directly into common imperial collets used in the United States. Please verify that your equipment’s clamping range is compatible to before placing an order. If necessary, use a reducer sleeve or a compatible spring collet.
