Maykestag Solid Carbide NC Machine Reamer 6.5mm Left Hand Spiral H7 Form B

Maykestag Solid Carbide NC Machine Reamer 6.5mm Left Hand Spiral

Professional 6.5mm solid carbide NC-machine reamer featuring a left-hand spiral, non-uniform pitch, Form B geometry and H7 cutting diameter tolerance for accurate finishing and precision sizing of pre-machined holes.

The Maykestag Code 5210 is a precision NC-machine reamer manufactured from solid carbide for accurately finishing previously drilled or machined holes to a controlled final diameter. Its left-hand spiral cutting geometry and non-uniform pitch are designed to provide a stable reaming action while helping reduce repetitive cutting forces that can contribute to vibration and chatter. The 6.5mm version features six cutting edges, an H7 cutting diameter tolerance and a precision h6 shank for accurate tool holding in suitable machine applications.

What is an NC-machine reamer? An NC-machine reamer is a precision finishing tool used after drilling, boring or another hole-making operation to bring an existing hole to its required final diameter and improve dimensional accuracy and surface finish. Unlike a drill, a reamer is intended to remove only a relatively small amount of material. The Code 5210 combines solid carbide construction with left-hand spiral flutes and non-uniform cutting-edge spacing for controlled precision reaming. Product highlights

• Solid carbide construction: VHM solid carbide provides high rigidity, wear resistance and dimensional stability for precision machining.
• 6.5mm reaming diameter: Designed for accurate final sizing of suitably prepared holes to the specified diameter.
• H7 cutting diameter tolerance: Precision-controlled reamer diameter for demanding hole-finishing applications.
• Left-hand spiral: Spiral-fluted cutting geometry provides controlled cutting action during machine reaming.
• Non-uniform pitch: Unequal cutting-edge spacing helps interrupt repetitive cutting forces and reduce the tendency for chatter during machining.
• Six cutting edges: Z = 6 geometry provides the cutting arrangement specified for this diameter in the Code 5210 series.
• Form B: Manufactured with the Form B geometry specified for this Maykestag reamer series.
• Similar to DIN 8093: The reamer design follows dimensional and geometric principles similar to DIN 8093.
• WN specification: Manufactured according to Maykestag's works-standard requirements for the Code 5210 series.
• Precision h6 shank: Controlled shank diameter tolerance supports accurate and repeatable tool holding.

Why Choose Maykestag?

Maykestag is an Austrian cutting-tool brand focused on precision-manufactured tooling for professional machining. Reaming is particularly sensitive to tool geometry, cutting-edge consistency and dimensional accuracy because only a small amount of material is removed during the finishing operation. Carefully controlled manufacturing therefore plays an important role in achieving repeatable hole size, surface quality and dependable tool life.

The Code 5210 series combines rigid solid carbide construction with precision H7 geometry, an h6 shank, left-hand spiral flutes and a non-uniform cutting-edge pitch. This makes the series particularly suited to workshops, toolrooms and production environments where repeatable hole finishing and accurate dimensional control are required.

Designed for Precision Hole Finishing

Reaming is normally performed after the hole has already been produced close to its final size. For this 6.5mm reamer, the catalogue indicates a recommended pre-hole diameter of 6.30mm, leaving a controlled amount of material for the reamer to remove. The solid carbide body provides the rigidity required for precision work, while the non-uniform pitch helps prevent all cutting edges from engaging the workpiece at identical intervals. When used with the correct cutting speed, feed rate, alignment and machining conditions, the Code 5210 is designed to produce accurate, repeatable finished holes with a controlled surface finish.
