3PC Step Drill Bit Set - Metric & Imperial Sizes, Hex Shank Cone Cutter for Thin Metal & Plastic, 3 Sizes Titanium Coated

Precision Drilling in One Set – For Metal, Plastic & More

This professional 3-piece step drill bit set is engineered to create clean, burr-free holes in thin materials with just one tool. Featuring both Metric and Imperial sizing markers laser-etched on each bit, it offers ultimate versatility for DIY projects, automotive work, plumbing, and electrical installations. The titanium coating reduces friction and extends bit life, while the hex shank prevents slipping in power drills.

Key Features: • Triple-Size Efficiency: One set covers small to medium hole needs (e.g., 4-12mm / 5/32"–1/2" range depending on configuration). • Dual Measurement System: Clear Metric (mm) and Imperial (inch) markings for global usability. • Hex Shank Design: Ensures secure grip in all standard drill chucks and impact drivers. • Titanium Nitride Coating: Enhances durability, reduces heat buildup, and allows smoother drilling. • Step Drill Design: Each bit gradually widens holes without swapping tools; ideal for thin metal sheets, PVC, acrylic, and wood. • Cone Geometry: Sharp stepped edges minimize tearing and produce clean, round holes.
