�AUq20�� i �����#���Q�1R�`���� �x����� Drill speed becomes increasingly important when drilling harder metals. In feet per minute. The metal being drilled. Checkout You should use a cutting speed chart to ensure you drill in the most efficient manner possible. The row below the material type is the Cutting Speed in Feet per Minute. The type of material will be highlighted in a set of columns. You should avoid exerting too much pressure or you will cause excessive heat build up which will hamper the cutting action. We have produced speed and feed charts for both metric and imperial drill bit sizes. 0000003060 00000 n Cutting paste : Information Google 0000000016 00000 n Cutting feeds and speeds, and the spindle speeds that are derived from them, are the ideal cutting conditions for a tool. jQuery( 'body' ).bind( 'wc_fragments_refreshed', function() { ga( 'ec:addProduct', {'id': ($(this).data('product_sku')) ? /* ]]> */ ","wrong_checkbox":"Checkbox","ignore_waypoints":"no","is_divi_theme_used":"1","widget_search_selector":".widget_search","ab_tests":[],"is_ab_testing_active":"","page_id":"1123","unique_test_id":"","ab_bounce_rate":"5","is_cache_plugin_active":"no","is_shortcode_tracking":"","tinymce_uri":""}; var et_builder_utils_params = {"condition":{"diviTheme":true,"extraTheme":false},"scrollLocations":["app","top"],"builderScrollLocations":{"desktop":"app","tablet":"app","phone":"app"},"onloadScrollLocation":"app","builderType":"fe"}; var et_frontend_scripts = {"builderCssContainerPrefix":"#et-boc","builderCssLayoutPrefix":"#et-boc .et-l"}; We have produced speed and feed charts for both metric and imperial drill bit sizes. Feed rate is the speed at which the drill bit travels through the item it is is drilling. Factors which will influence drilling speed and feed, and therefore you must considered, when drilling metal include: Where drilling cutting speed is not the primary focus it is advisable that you use a slower speed than recommended as this will help you prolong the life of your drill bit. The diameter of the hole being drilled. Drill bit cutting speeds are very important in the drilling of metals. document,'script','https://connect.facebook.net/en_US/fbevents.js'); Therefore feed rates and speeds can be accurately adjusted. Facebook /* */ The larger the diameter of the hole you are drilling the larger the surface area where metal is in contact with metal as a result heat build up will be faster.
