Yougfin Step Drill Bits with Automotive Center Punch,Unibit Titanium Coated High Speed Steel Step Bit Set for Hole Drilling,50 Sizes with Aluminum Case for DIY Lovers,5+1pcs

【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 sheet metal working and are ideal for cutting non-ferrous metals, plastic, wood board, etc.
【Extra Automatic Center Punch】：You know how when you try to drill into metal or hard surfaces and your drill bit "walks" no matter how much you think it's steady? Yeah, we have a tool for that. The automatic center punch has a heavy-spring action, and you simply place the tip where you want to drill, and it punches a slight indentation in the surface. Just enough so that the drill bit won't walk.
【118° Split Point】：These step drill bits have a small point angle of 118° and require 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】：These drill bits feature a special dual flute straight design for dependable performance and durability. And the shanks on these step drill bits have three f....
