• 【High Quality Material】： High-speed steel, also known as HSS, is the most common drill bit for metal applications. It incorporates an element with titanium that makes the drill bit harder than a typical HSS bit and thus suitable for precision drilling in stainless steel and other hard materials
• 【10-Step Sizes】： This cone-shaped bit has steps of increasing diameter marked along its cutting head. High-visibility size marks for primary hole sizes will really save your time during drilling! 10-step sizes include 1/4", 3/8", 1/2", 5/8", 3/4", 7/8", 1", 1-1/8", 1-1/4", 1-3/8"
• 【118° Split Point】： This step drill has a small point angle of 118° and requires less pressure when centering in the material. The point starts drilling at contact, reducing friction, pressure, and heat. The larger the point angle, the higher the contact pressure and the centering in the material requires more pressure
• 【Double Flutes & Tri-Flatted】： This drill bit features a special dual flute straight design for dependable performance and durability. And the shank on this step drill bit has three flats that help prevent the bit from slipping in the drill chuck during drilling
• 【Application & Tip】：Step drills are ideal for sheet metal working and are suitable for cutting non-ferrous metals, plastic,etc. ***Tip***：Please keep the bit perpendicular to the mateial during operation to prevent it from breakage.
