Titanium-Coated High-Speed Steel Drill Bits

HSS Titanium Coating Our high-speed steel drill bits are enhanced with a titanium coating, making them harder than typical HSS bits. This coating significantly reduces friction, improving drill performance and durability in various heat, corrosion, and rust-resistant applications.

Precision-Engineered Design

Two-Flute Spiral Grooved Design Our drill bits feature a two-flute spiral grooved design that deburs chips, dust, and debris, providing clearance and smooth cutting. The 118° split point tip effectively reduces friction, pressure, and heat, ensuring longer-lasting and more efficient drilling.

Wide Application

Diverse Material Suitability Our step drill bits are versatile and can process holes of different diameters, suitable for materials such as metal, iron, aluminum, brass, plastic, aluminum alloy, wood, and more. Ideal for home DIY projects and general use.
