Versatile 3-Piece Set for Every Job
This Kulkoin set provides you with the three most essential step drill sizes, ensuring you have the right tool for a wide range of hole diameters:

• 4mm – 12mm: For smaller, precision holes in control panels and thin materials.

• 4mm – 20mm: A versatile mid-range bit for general electrical and sheet metal work.

• 4mm – 32mm: The large bit for creating wide holes for conduit, wire harnesses, and cable glands.

Premium HSS Titanium Coated Construction
The Kulkoin step bits are manufactured from High-Speed Steel and feature a titanium nitride coating. This combination provides several critical benefits:

• Extended Tool Life: The titanium coating significantly increases surface hardness and reduces wear, keeping the bits sharper for longer.

• Reduced Friction: The coating creates a smoother surface that reduces friction and heat buildup during drilling, preventing material from sticking to the bit.

• Faster, Cleaner Cuts: The sharp, precision-ground edges of the HSS material, combined with the low-friction coating, allow for fast, burr-free holes without the need for center punching.

• Corrosion Resistance: The coating also provides protection against rust and corrosion.

Key Features and Benefits

• Deburred Holes: The unique step design naturally deburrs the hole as you drill, eliminating the need for a separate deburring tool and ensuring a clean finish safe for wiring.

• No Center Punch Needed: The split point tip prevents walking, allowing you to drill accurately without pre-punching, saving time and effort.

• Self-Start Design: The angled tip allows the bit to easily grab and start cutting into the material, providing excellent control from the very beginning.

• High-Speed Cutting: Engineered for rapid material removal in thin materials like sheet metal and plastics.

• 3/8″ Hex Shank: Provides a secure grip in standard drill chucks and prevents slipping during operation.

What Materials Can I Drill?
These Kulkoin step bits are designed for use on a variety of materials, including:

• Sheet Metal: Steel, stainless steel, aluminum, and copper up to approximately 5mm thick.

• Plastics: Acrylic, PVC, polycarbonate, and other rigid plastics.

• Wood: Plywood and thin hardwoods.

• Drywall: For creating clean holes for electrical boxes.

How to Use Your Step Drill Bit
Using a step bit is simple and efficient:

1. Mark Your Spot: Mark the center of your desired hole location.

2. Position and Start: Place the tip of the step bit on your mark and begin drilling at a moderate speed. The self-starting tip will prevent walking.

3. Drill to the Correct Step: Advance the bit until the step corresponding to your desired hole diameter reaches the surface of the material.

4. Retrieve and Finish: Withdraw the bit. 3pcs step bit Kulkoin hole will be clean, circular, and naturally deburred.

Pro Tip for Best Results
For optimal performance, especially in metal, use a lubricant like cutting oil or WD-40 to reduce friction, cool the bit, and achieve an even smoother cut. Always use a variable speed3pcs step bit Kulkoin  to a lower RPM for metal drilling.
