Key Features

• ✅ COBALT STEEL - Manufactured from M35 grade cobalt steel, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67, for much faster cutting and extra longer life span, with up to twelve times when compared with an average HSS drill bit.
• ✅ SELF CENTERING - the 135°quick-cut splint point is self-centering and will penetrate quickly with less pressure. Will not "walk" or "wander"
• ✅ FOR STAINLESS STEEL - Particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too. Not for hardened steel / high carbon steel. Try to adjust the RPM when it fails to penetrate.
• ✅ 10PC SET - The set includes 10pcs of 3/16" diameter M35 grade cobalt steel twist drill bits. Packed in a plastic case for easy storage and carrying. Manufactured to German DIN338 standard.
• ✅ DOWNLOADABLE USER GUIDE - We've summed up some tips of drilling metals, including a RPM chart for several common metals, based on our reviews and some articles on the internet. In most cases, our customers would get a much better result with these tips. Welcome to download.
