4Mm H7 Chucking Reamer Solid Carbide 4 Spiral Flutes Straight Shank Reamer

Specifications: Accuracy: H7 Cutting diameter: 4mm / 0.16" Shank diameter: 4mm / 0.16" Flute length: 24mm / 0.95" Overall length: 50mm / 1.97" Material: Solid Carbide Features: Spiral flute, straight shank Flutes quantity: 4 Cutting hardness (max): HRC55 Package content :1 x Chucking reamer Descriptions: Reamer tools are designed for precision machining, smoothing or finishing of holes. They are not only used in drilling machines, milling machines, lathes, screw machines and machining centers, but also widely used in various parts of machinery, such as gears, bearings, bushings, etc. Spiral reamers allow chips and debris to run easily from the hole, which is very suitable for most shallow cutting applications and suitable for use in through holes or blind holes without interruption, such as keyway. Straight shank can be used with a variety of tool holder systems and fixed in the tool holder to prevent the reamer from slipping in high torque applications. Carbide reamer drill bits have only a base layer without any additional coating and can be used in a variety of materials, including brass, copper, mild steel, plastic and composite materials, with stable cutting ability and long working life without worrying about breakage or deformation. During the cutting process, please maintain a stable cutting dynamics and feed dynamics, and use appropriate cutting lubricants or coolant to cool and lubricate the tool, which will help reduce cutting temperature, extend tool life and improve processing quality.
