Step Drill Bit Set Unibit 5PCS,HSS Titanium Coated, 50 Sizes High Speed Steel for Metal, Sheet Metal, Plastic & Wood, with Automatic Center Punch & Aluminum Case

Key features

• Premium Quality: Our step drill bits are made of high-speed steel with added titanium, making them harder than standard HSS bits and ideal for cutting non-ferrous metals, plastic, wood boards, and more.
• Automatic Center Punch: Say goodbye to "walking" drill bits with our included heavy-spring action automatic center punch. Simply place it where you want to drill, and it creates a slight indentation to keep your bit in place.
• 118° Split Point: Our step drill bits feature a point angle of 118°, which reduces friction, pressure, and heat while centering in the material. This means less pressure is required to start drilling and fewer errors or broken bits.
• Dependable Design: Our drill bits feature dual flute straight design for performance and durability, along with tri-flatted shanks to prevent slipping in the drill chuck during drilling.
• 5 Drill Bits, 50 Step Sizes: Our assortment comes with 5 drill bits and a combined 50-step sizes ranging from 1/8" to 1-3/8", allowing for a wide range of drilling requirements and precise hole size selection.
