Here, G\u00fchring offers a material specialist: The solid carbide drill RT 100 Inox with a 140\u00b0 point angle and 30\u00b0 pitch. Tools with adapted geometry are used for machining stainless steels, which reduce the temperature development and produce short chips in these long-chipping materials. For optimum results, solid carbide drills with a suitable hard coating should be used.<\/p>\n [\/et_pb_toggle][et_pb_toggle title=”Which drills for hardened steel?” _builder_version=”4.27.6″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]Hardened steel is steel heated to a temperature of 750 to 1050 \u00b0C to increase its mechanical resistance. The use of a solid carbide drill bit with a Signum coating, such as the ratio drill RT 100 HF<\/a> from G\u00fchring, is recommended here.<\/p>\n The microstructure of the Signum coating is characterised by extremely fine TiAlN nanocrystals, which are embedded in a glass-like, high-temperature-resistant silicon nitride matrix.

The microstructure of cutting edges indicates under the microscope whether the cutting edge is sharp (chiselled) or rounded. Cutting edge chipping is avoided in high-quality drills, thus increasing their stability and surface quality. Cutting edge preparation processes include wet blasting, micro-blasting, drag grinding and brushing using robots.<\/p>\n [\/et_pb_toggle][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_row custom_padding_last_edited=”on|desktop” module_class=”gue-adbox” _builder_version=”4.27.4″ _module_preset=”default” custom_padding_tablet=”” custom_padding_phone=”” animation_direction=”left” saved_tabs=”all” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/guehring.com\/wp-content\/uploads\/2024\/02\/GUE_website-pikto_academy.svg” _builder_version=”4.24.2″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.5″ _module_preset=”default” link_option_url=”https:\/\/academy.guehring.de\/” link_option_url_new_window=”on” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ module_id=”twist-drill” _builder_version=”4.22.1″ _module_preset=”default” global_colors_info=”{}”][et_pb_row module_class=”gue-row-1col-text-centered” _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n Twist drill is a generic term for different drill types such as metal drills, plastic drills, wood drills, universal drills, as well as stone and concrete drills.

Thanks to its favourable cutting angle, the drill is easy to center. The chip removal runs automatically with the twist drill and is partially supported by the supply of cooling lubricant through integrated cooling channels. The twist drill can also be reground several times.

A distinction is made here between the clearance angle (alpha), the wedge angle (beta) and the rake angle (gamma). The clearance angle is ground into the tool to enable it to cut, and therefore has a decisive impact on the maximum feed rate. At the same time, it influences the friction between the clearance face of the cutting wedge and the cutting surface of the workpiece. A small clearance angle is suitable for hard and short-chipping materials, e.g. for high-alloy steel.<\/p>\n [\/et_pb_toggle][et_pb_toggle title=”Grinding twist drills ” _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n The enormous range of materials to be machined requires a wide variety of grinding shapes.<\/p>\n With the grinding form A, the chisel edge is sharpened to reduce the axial forces. This means that in an additional working step with a grinding wheel, the chisel edge is reduced at defined angles.<\/p>\n Grinding form B is suitable for long-chipping materials such as structural steel and high-strength steel. It is a combination of form A and a main cutting edge correction. Here, the positive rake angle is corrected by a surface and the cutting wedge is ground \u201cblunt\u201d. This increases the resistance for the chip when drilling into the full. Chip packs form on the corrected surface, which are broken and transported away via the flutes.<\/p>\n The grinding form C corresponds to cross-grinding. With this type of grind, two surfaces are ground to each other so that they intersect at the chisel edge. This ensures excellent centring properties and lower feed forces. This allows the cross-grinding to produce more precise hole diameters and a perfect, round hole.<\/p>\n The grinding form D is a combination of form A and an additional point angle of usually 90\u00b0. It removes the cutting edge corner, creating two new, less sharp cutting corners. This makes the tool less sensitive to impact loads and increases its tool life. This grinding is mainly used in metalworking for grey cast iron, malleable cast iron and forged parts.<\/p>\n With grinding form E is a so-called centre point is ground. This geometry is characterised by excellent centring properties and a precise hole with a low burr development. This point is used for thin-walled workpieces, sheet metal and soft materials.<\/p>\n [\/et_pb_toggle][et_pb_toggle title=”Twist drill set” _builder_version=”4.27.6″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]Twist drill sets<\/a> from G\u00fchring are available in different versions and with different surface treatments.

Due to the increased cutting values, tool lives and improved drilling qualities, carbide tools are ideal for series and large-scale production on CNC machines with stable clamping setup. However, the purchase price for carbide tools is significantly higher compared to HSS tools. Therefore, carbide is not always the most economical solution for machining.

The competences of tool materials are clearly distributed \u2013 and carbide has by no means won over all areas of application.

Alloy components such as tungsten, molybdenum and cobalt are responsible for these properties. The higher the alloy components, the higher the tempering resistance, wear resistance and performance of the tool, but also the higher the purchase price. Therefore, when selecting the cutting material, it is important to consider how many holes will be produced in which material. For a small number of holes, the cheapest tool material HSS is recommended. For series production, higher-quality tool materials such as HSCO, M42 or HSS-E-PM should be selected.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.5″ _module_preset=”default” global_colors_info=”{}”]<\/p>\nSophisticated drill technology<\/h2>\n
