Specification Brand : HARFINGTON BulletPoint1 : Size - Cutting Diameter: 7.7mm / 0.303"; Cutting Length: 35mm / 1.38"; Overall Length: 70mm / 2.76"; Shank Diameter: 7.69mm / 0.3028"; Reamer Shape: Straight Flute Straight Shank; Color: Black; Coating: Uncoated. BulletPoint2 : Material- This straight flute reamer is made of solid carbide and has the characteristics of high hardness, high strength, strong wear resistance, good corrosion resistance, and excellent thermal stability. These properties enable the reamer to always maintain stable cutting capabilities and a long working life—no need to worry about breakage or deformation. BulletPoint3 : Feature - Our chucking reamers adopt a straight groove design. There are multiple straight grooves on the reamer to discharge chips and cooling lubricant and help distribute the cutting force evenly during the cutting process, thereby improving processing efficiency. BulletPoint4 : Application - Machine reamers can achieve high-precision and high-efficiency reaming processing of various metal materials, such as steel, cast iron, aluminum alloys, etc. They are suitable for all types of CNC machine tools, lathes, and machining center equipment. BulletPoint5 : Note - During the cutting process, please maintain stable cutting force and feed force, and use appropriate cutting lubricant or coolant to cool and lubricate the tool, which will help reduce cutting temperature, extend tool life, and improve processing quality. BulletPoint6 : Versatile Chuck Compatibility: Straight shank with 3-equal-flats design, fitting both 3/8'' and 1/2" chucks for diverse drilling needs. BulletPoint7 : Sizes Included: Set includes 3/8", 1/2", 5/8", and 3/4" reamers, catering to a variety of hole enlarging tasks. BulletPoint8 : Durable Gold Oxide Finish: Each reamer features a gold oxide finish with a spiral flute design, offering enhanced durability and efficient chip removal. BulletPoint9 : Precision Engineering: Straight shank with stop collar prevents over-penetration, ensuring precise hole dimensions.

Our chucking reamers adopt a straight groove design. There are multiple straight grooves on the reamer to discharge chips and cooling lubricant and help distribute the cutting force evenly during the cutting process, thereby improving processing efficiency. There is no coating layer on the surface of the uncoated reamer, so the reamer is not easy to adhere to cutting chips and cutting fluid, which makes cleaning and maintenance easier and reduces downtime during the production process. Machine reamers can achieve high-precision and high-efficiency reaming processing of various metal materials, such as steel, cast iron, aluminum alloys, etc. They are suitable for all types of CNC machine tools, lathes, and machining center equipment.
