One Drill, Multiple Hole Sizes – Effortless Precision!
The MARIKON 3-Piece Black Nitride Step Drill Bit Set revolutionizes drilling with multi-size capability in a single bit. Perfect for wood, metal, and plastic, these high-speed steel (HSS) step drills eliminate the need for multiple bits, saving time and workspace clutter.
Why This Set Stands Out:
✔ 3 Versatile Sizes – Covers 3-12mm, 4-12mm, and 4-20mm holes in one compact set.
✔ Black Nitride Coating – Boosts durability and reduces heat buildup for smoother drilling.
✔ Straight Flute Design – Prevents jamming and ensures clean, splinter-free edges.
✔ HSS Construction – Stays sharp longer, even with repeated use on hard materials.
Ideal for These Tasks:
→ Carpenters – Drill hinge holes (4-12mm) or cabinet knobs (3-12mm) with ease.
→ Metalworkers – Enlarge holes in sheet metal (4-20mm) without burrs.
→ Plumbers – Create clean openings in PVC pipes for fittings.
→ Electricians – Adjust junction box holes or conduit entries.
Who Needs These Step Drills?
• DIY Home Improvers – Replace a drawer full of single-size bits with this space-saving set.
• Workshop Pros – Speed up projects with fewer tool changes.
• Crafters – Perfect for resin molds, leather holes, or acrylic displays.
Upgrade your toolkit with these precision step drills – drill smarter, not harder!
