Maykestag HSS-E NC Machine Reamer 9.99mm Nominal Shank Form D

Maykestag HSS-E NC Machine Reamer 9.99mm With Nominal Shank

Professional 9.99mm NC-machine reamer manufactured from HSS-E, featuring a nominal 10.00mm h6 shank, Form D geometry, six cutting edges and precision dimensions for accurate machine reaming. Manufactured to Maykestag WN specifications and similar to DIN 212.

The Maykestag Code 3082 is a precision NC-machine reamer designed for the accurate finishing and sizing of pre-machined holes. The reamer removes a small, controlled amount of material from an existing hole to improve dimensional accuracy, roundness and surface finish. Its HSS-E construction provides the toughness and heat resistance required for professional machining, while the nominal h6 shank provides accurate and secure tool holding in suitable machine-tool systems.

What is an NC-machine reamer? An NC-machine reamer is a precision finishing tool used after drilling or pre-machining a hole. Unlike a drill, which creates the initial hole, a reamer removes only a small amount of material to bring the bore to its required finished diameter and improve its surface quality. NC-machine reamers are designed for controlled machine use where accurate positioning, repeatability and dimensional consistency are important. Product highlights

• Nominal shank: Features a 10.00mm nominal shank with an h6 tolerance for accurate and secure machine-tool holding.
• Six cutting edges: The Z6 cutting geometry provides controlled and consistent material removal during precision hole finishing.
• Form D: Manufactured with the Maykestag-specified Form D reamer geometry for machine reaming applications.
• Similar to DIN 212: Dimensional design follows a configuration similar to the DIN 212 standard.
• WN specification: Manufactured according to Maykestag's works-standard dimensional and geometry requirements for the Code 3082 series.
• 9.80mm recommended pre-hole: Catalogue data specifies a 9.80mm pre-machined hole diameter for the 9.99mm reamer.

Why Choose Maykestag?

Maykestag is an Austrian cutting-tool brand focused on precision-manufactured tools for professional machining. With reaming operations, consistent cutting geometry and closely controlled dimensions are particularly important because the tool is responsible for establishing the final size and surface quality of the hole.

The Code 3082 series combines HSS-E tool material with Form D geometry, nominal h6 shanks and precisely defined cutting dimensions. The series covers fine diameter increments from 1.00mm through 12.03mm, providing machine shops and production environments with precise sizing options for demanding hole-finishing applications.

Designed for Precision Hole Finishing

The Code 3082 NC-machine reamer is intended to follow a correctly sized pre-machined hole and remove only the material required to achieve the finished bore. Its six-edge cutting geometry provides controlled engagement with the workpiece, while the precision nominal shank supports accurate tool location in the machine. Correct pre-hole size, cutting speed, feed rate, lubrication and machine alignment are essential for achieving good dimensional accuracy, surface finish and tool life.
