New standard <\/span>
This reamer is a perfect fit for every diameter range<\/span><\/h1>\n

When it comes to demand for high-quality surfaces, excellent hole qualities and tight diameter tolerances, the HR 500 high-performance reamer has been raising the bar for years. G\u00fchring is now creating the next sensation by expanding the product\u2019s diameter range by +-0.05 mm increments. The result: With the new fixed-size reamers in 5\u00b5 increments, G\u00fchring covers all tolerance ranges with a precision-fit. <\/p>\n

If you\u2019d like to avoid using an expensive special tool for producing tight tolerances outside the H7 fit system, then opt for a reamer from one of our fixed sizes. Conventional models only offer dimensions in 1\/100 increments and \u00b1 0.03 mm in their range. The result? The reamers are only suitable to a limited extent.<\/p>\n

This is now set to change with G\u00fchring: Thanks to new fixed-size reamers from \u00b1 0.05 mm and dimensions in 5\u03bc increments, G\u00fchring is closing the gap in the market and covering numerous tolerances even outside the H7 class. And it does this with a great deal of precision as standard \u2013 without making any compromises or using custom-made products. As a result, customers benefit from over 100% more wear buffer and double the tool lives in selected fits when they purchase one of these high-performance reamers.<\/p>\n

The new intermediate dimensions for the HR 500 high-performance reamer in 5\u03bc increments cover all tolerance ranges with high precision \u2013 for 125% more reaming performance. Using the example of tolerance 11 F7, we will now demonstrate what this means for your tool selection:[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”3_5,2_5″ module_class=”gue-row-vertical-aligned-content gue-row-2col-image-text” _builder_version=”4.22.2″ _module_preset=”default” locked=”off” global_colors_info=”{}”][et_pb_column type=”3_5″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/guehring.com\/wp-content\/uploads\/2024\/06\/GUE_toleranzbereiche-diagramm.jpg” alt=”Diagramm einer technischen Zeichnung f\u00fcr Passungen mit Darstellung der Ma\u00dftoleranzen und Passungsbereiche” title_text=”Diagramm einer technischen Zeichnung f\u00fcr Passungen mit Darstellung der Ma\u00dftoleranzen und Passungsbereiche” _builder_version=”4.25.2″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text module_class=”gue-caption” _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

Example tolerance 11 F7<\/h3>\n

\u00d8 11,010<\/strong>: The reamer does not fall within the required tolerance range of the hole. The hole is too small.<\/p>\n

\u00d8 11,020<\/strong>: The reamer falls within the required tolerance range of the hole. However, the wear buffer for the lower tolerance variable is only 0.004 \u00b5. The tool wears prematurely, the hole is too small.<\/p>\n

\u00d8 11,030<\/strong>: The reamer falls within the required tolerance range of the hole, but exceeds the upper tolerance variable. Risk of the hole being too large.<\/p>\n

\u00d8 11,025 (SOLUTION)<\/strong>: With the new standard programme in the 5\/1000 range, G\u00fchring covers all tolerance ranges with a precise fit. This results in article #1675 11.025<\/p>\n

HR 500 <\/span>
\nMaximum precision<\/span><\/h2>\n

The HR 500 high-performance tool has been on the market for 20 years and no other conventional machine or NC reamer has come close to reaching its level of performance. Made exclusively in Baden-W\u00fcrttemberg, this successful product incorporates a great deal of expertise as we work hard to continuously optimise and enhance its concept and guarantee the highest production quality.<\/p>\n

The product\u2019s high performance is based on a combination of cutting edge geometry, the use of a special carbide and the coating. The universal use of these reamers allows them to be used in a wide range of materials, guaranteeing you maximum flexibility in your projects. The HR 500 family also includes tool variants for almost all materials.<\/p>\n
