About This

• HSS step drill with Titanium Coating: High-speed steel material ensures a longer service life.This unibit step drill bit features advanced heat/corrosion/rust resistant coating, specially engineered for demanding metal drilling applications.
• 118° Split Point Tip & Spiral Dual-flute Design: increases cutting speed with self-centering and prevents walking, clears chips faster and allows particles to escape more easily.
• Widely Application: Ideal for drilling holes in plastic, aluminum, iron and many other types of sheet metal (Not recommended for stainless steel or any other harder metal).
• Two Spiral Flutes stepped drill bit: The dual-flute design ensures faster chip removal and cleaner holes. This step drill bits for metal provides smoother cutting while efficiently evacuating chips for peak drilling performance.
