Sumitomo SR101 SRKG101-76-40-060 Coolant Thru Reamer Head
Overview
The Sumitomo SR101 SRKG101-76-40-060 Coolant Thru Reamer Head is a precision cutting tool designed for industrial machining. It is identified by the SR101 series reference and the SRKG101-76-40-060 part number. The reamer head covers a diameter range of 80.601mm to 100.6mm. It is used to finish holes to accurate size and smooth surface quality. The coolant thru design allows cutting fluid to reach the cutting zone directly, improving chip evacuation and tool life. The modular construction allows the head to be mounted on compatible tool holders. This makes it adaptable to different machining setups. The reamer head is suitable for production machining and precision manufacturing.
Reaming Function
Reaming is a machining process that improves the accuracy and finish of an existing hole. The reamer head removes a small amount of material to bring the hole to the required diameter. It also corrects minor errors in roundness and straightness. The Sumitomo SR101 reamer head uses precision cutting edges to achieve a smooth surface. The coolant thru feature helps flush chips away from the cutting zone and reduces heat. This is important when machining deep holes or tough materials. Proper alignment and speed are important for good results. The reamer should be used with appropriate coolant and feed rates. Regular inspection helps maintain performance.
Design and Construction
The Sumitomo SRKG101-76-40-060 reamer head is made from high quality tool steel or carbide. The cutting edges are ground to precise geometry. The body is designed for rigidity and accurate rotation. The modular interface provides a secure connection to the tool holder. Coolant passages are built into the head to deliver fluid to the cutting edges. The head may include adjustment features for fine sizing. The tool is balanced for smooth operation at recommended speeds. Proper handling and storage help prevent damage to the cutting edges. The design supports reliable performance in demanding machining environments.
Compatibility and Setup
Technicians should confirm that the reamer head matches the required hole size and tool holder interface. The SR101 and SRKG101-76-40-060 references help identify the correct tool. The tool holder and machine spindle should be clean and in good condition. The reamer should be mounted securely and checked for runout. Cutting speed and feed should be selected according to the workpiece material. Coolant should be directed to the cutting zone at the recommended pressure and flow. After machining, the hole should be measured to confirm size and finish. Following approved setup procedures helps ensure accurate results and long tool life.
Applications
The Sumitomo SR101 Coolant Thru Reamer Head is used in many machining applications. It is common in automotive, aerospace, and general engineering production. It is used on machining centers, lathes, and specialty reaming machines. The tool is suitable for finishing holes in steel, cast iron, aluminum, and other materials. In production, it helps maintain consistent hole quality and reduce cycle time. In maintenance shops, it supports repair and reconditioning work. For machinists, understanding the reamer function helps achieve accurate results. For production managers, reliable tooling helps maintain throughput and quality.
Maintenance and Care
Regular maintenance helps extend the life of the reamer head. The cutting edges should be inspected for wear and chipping. The tool should be cleaned after use to remove chips and coolant residue. Coolant passages should be checked for blockage. The modular interface should be checked for damage and cleaned before mounting. The tool should be stored in a protective case. Cutting parameters should be reviewed if hole quality changes. Worn or damaged reamer heads should be replaced promptly. Following these practices helps maintain accurate hole finishing and reduces machining costs.
