COBALT GOLD OXIDE JOBBER DRILL BITS: 29 PCS high speed steel with 5% cobalt drill bit set resists high heat abrasion while drilling. Cobalt steel provides extended tool life compared to high-speed steel drill bits, and maintains the tool's toughness and hardness in high drilling temperatures. A gold oxide finish acts as a lubricant and provides wear resistance. WIDE APPLICATIONS: HIGHFIRE 29 PCS set with sharp and hard cutting edge is ideal for versatile applications especially for projects made from stainless steel, such as kitchenware maintenance, machine parts, medical equipment and DIY projects. It can also be used to drill cast iron, high temperature alloy, titanium alloy and even hard plastics and wood. ROUND AND PORTABLE CASE: Say goodbye to constant losing or misplacing your drill bits! HIGHFIRE cobalt drill bit set for metal comes with an ergonomic and portable round carrying case with built-in clip. The case can be easily attached to your tool belt keeping your bits within immediate reach! 135 DEGREES SPLIT POINT TWIST DRILL BITS: A self-centering 135° split point drill tip penetrates hard materials without a pilot hole and keeps sharp without walking on the surface compared to a 118-degree point. Proper twist and flute design clears chips and particles fast. Drill bits larger than 3/8" have 3/8” reduced shank for majority drills in the market. Drill bits smaller than 3/8" have three-flat shanks that reduce spinning in chuck.
