The solid carbide machine reamers for automatic machines with centesimal diameter progression, made from K20 micrograin carbide and Latuma coated, are precision tools designed for finishing pre-machined holes in professional machining operations. They are suitable when a controlled final diameter, good surface quality and high repeatability in production cycles are required. The centesimal progression allows the most suitable diameter to be selected according to the required size, making the tool particularly useful in applications where the hole must meet precise tolerances.

The automatic machine design, type DIN 8089, makes these reamers suitable for repetitive operations on automatic lathes, transfer machines, machining centres and production systems where stability and consistent results are essential. In these applications, the tool must maintain cutting accuracy, regular hole geometry and reliability even over large production batches.

The solid carbide construction in K20 micrograin provides high hardness, wear resistance and dimensional stability. Compared with high-speed steel tools, it offers longer cutting edge life and better performance retention in operations where constant accuracy and reduced wear over time are required. The micrograin structure contributes to cutting edge strength and finishing quality.

The Latuma coating adds a further advantage in professional and repetitive applications, as it protects the cutting edges and helps maintain more stable tool behaviour during reaming. This feature is useful when the tool works in continuous cycles, on demanding materials or in production where constant hole quality must be maintained over a large number of parts.

The left-hand helix 6° cutting edges support controlled hole finishing and good stability during removal of the machining allowance. The reamer must be used on an already prepared hole with correct and uniform allowance. Accurate pre-hole preparation is essential to avoid vibration, scoring, ovality, abnormal cutting edge wear and inconsistent dimensional results.

During use, correct alignment between machine, tool and workpiece should be checked. The rigidity of the clamping system directly affects hole accuracy and internal surface quality. Suitable cutting parameters, regular feed and correct lubrication or coolant use help make the most of the solid carbide structure and Latuma coating, reducing friction and maintaining a stable machined diameter.

These reamers are suitable for finishing holes in series-produced mechanical parts, fitting seats, precision components, small metal parts, assembly elements and workpieces machined on automatic machines. They are particularly useful when the same dimension must be repeated on multiple parts while maintaining dimensional consistency and good surface quality.

For good results, it is advisable to select the correct centesimal diameter according to the required final size, prepare the hole with the proper allowance, avoid excessive material removal and regularly check the condition of the cutting edges. The Latuma coating supports tool life, but it does not replace the need for correct hole preparation, stable clamping and working parameters consistent with the material.

The solid carbide machine reamers for automatic machines in K20 micrograin with Latuma coating are therefore a technical solution for precise, repeatable and highly stable finishing operations. The combination of DIN 8089 type, centesimal diameter progression, solid carbide construction, K20 micrograin, left-hand helix 6° and Latuma coating makes them suitable for production departments, precision workshops and industrial applications where hole quality and tool life are essential requirements.
