Determine the cost per hole by dividing the bit&#8217;s price by the total holes drilled. Cheaper bits could potentially have a higher cost per hole than more resilient options. Notably, in our test, Bosch PointTeQ&#8217;s non-cobalt bit couldn&#8217;t drill any holes, whereas the Adiseal Ultimate metal drill bit successfully drilled 135 holes.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Example of cost per hole<\/h4>\n\n\n\n<p>To compare costs, let&#8217;s consider drilling 10 holes in 6mm stainless steel with the Adiseal Ultimate and Bosch cobalt drill bits.<\/p>\n\n\n\n<p><a href=\"https:\/\/guglue.com\/product\/adiseal-ultimate-metal-drill-bit-10mm-x-133mm-cobalt\/\">Adiseal Ultimate 10mm metal drill bit<\/a> price: \u00a310.14<br>Cost per hole (\u00a310.14 \/ 135 holes): \u00a30.076666<br>Cost to drill 10 holes: \u00a30.77<\/p>\n\n\n\n<p>Bosch cobalt metal drill bit price: \u00a38.31<br>Cost per hole (\u00a38.31 \/ 15 holes): \u00a30.554<br>Cost to drill 10 holes: \u00a35.54<\/p>\n\n\n\n<p>Based on cost per hole, Adiseal is more cost-effective. Further savings can be observed as detailed below.<\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Saves time<\/h3>\n\n\n\n<p>A drill bit that drills faster not only decreases the cost per hole but also lowers labor expenses. The reduced drilling time per hole leads to additional cost savings overall.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Example of saving money on labour cost<\/h4>\n\n\n\n<p>To showcase potential labour cost savings, let&#8217;s examine the time and effort needed to drill 10 holes in 6mm stainless steel using the Adiseal Ultimate and Bosch cobalt bits.<\/p>\n\n\n\n<p>Assuming a construction contractor pays \u00a320 per hour for a tradesperson&#8217;s work, it amounts to \u00a30.00555 per second.<\/p>\n\n\n\n<p>Adiseal Ultimate: 317 seconds to drill 10 holes.<br>Labour cost: \u00a31.76<\/p>\n\n\n\n<p>Bosch cobalt: 1324 seconds to drill 10 holes.<br>Labour cost: \u00a37.36<\/p>\n\n\n\n<p>Adding these labour costs to the drilling costs above, total cost to drill 10 holes is:<br><strong>Adiseal Ultimate: \u00a32.53<br>Bosch cobalt: \u00a312.90<\/strong><\/p>\n\n\n\n<p>In reality, further savings arise from extended tool lifespan, decreased energy consumption per hole, and fewer trips required to purchase replacement bits.<\/p>\n\n\n\n<p><br><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Saves tools<\/h3>\n\n\n\n<p>Quicker drilling extends the tool&#8217;s lifespan by minimizing usage.

They&#8217;re designed with a blend of cobalt and high-speed steel for durability and heat resistance, ideal for high-temperature drilling in these materials. Their enhanced strength makes them effective where regular bits might struggle or wear out.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1701125566869\"><strong class=\"schema-faq-question\">Are cobalt drill bits the strongest?<\/strong> <p class=\"schema-faq-answer\">Cobalt drill bits are some of the strongest options for tough materials like stainless steel. They&#8217;re highly durable and heat-resistant due to their blend of cobalt and high-speed steel. While they&#8217;re quite strong, there might be specialized drill bits with unique compositions designed for specific purposes that are also exceptionally robust.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1701125630027\"><strong class=\"schema-faq-question\">What is the difference between 5% and 8% cobalt drill?<\/strong> <p class=\"schema-faq-answer\">The cobalt percentage in drill bits indicates the cobalt content in the high-speed steel (HSS) used.<br\/>5% Cobalt Bits: These contain around 5% cobalt, offering decent durability for general drilling in materials like steel, aluminum, and wood. They might not handle extreme heat as well as higher cobalt content bits.<br\/>8% Cobalt Bits: With roughly 8% cobalt, these bits are more heat-resistant and durable. They&#8217;re suitable for harder materials like stainless steel and cast iron, handling higher drilling temperatures effectively.<br\/>Higher cobalt content generally improves heat resistance and durability, especially for challenging drilling tasks.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1701125896062\"><strong class=\"schema-faq-question\">Can I use cobalt drill bits on wood?<\/strong> <p class=\"schema-faq-answer\">While cobalt drill bits can be used on wood, they&#8217;re primarily designed for tough materials like stainless steel and cast iron. For woodworking, standard high-speed steel (HSS) or brad point drill bits are more suitable, offering efficient and precise drilling in wood. Cobalt bits might work on wood, but they might not provide the same precision or efficiency as bits designed specifically for woodworking tasks.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1701126019180\"><strong class=\"schema-faq-question\">Will a cobalt bit drill stainless steel?<\/strong> <p class=\"schema-faq-answer\">Yes, cobalt drill bits are specifically designed to drill through tough materials like stainless steel. Their construction, which often includes a mix of cobalt and high-speed steel (HSS), provides enhanced durability and heat resistance, making them well-suited for drilling into stainless steel and other hard alloys.
