5Pcs 15-35mm Forstner Drill Bit Set

The 5-piece 15-35mm Forstner Drill Bit Set includes:

1. Forstner bits crafted from tungsten carbide for superior strength, hardness, wear, and heat resistance, with a painted surface to enhance rust and corrosion resistance.

2. A spike design for precise wood drilling, preventing slippage and ensuring accurate hole starts. The head's 2 flutes, 3 spurs, and arc curve design reduce cutting resistance, increase efficiency, and expedite debris removal.

3. Heat-treated bits that can be resharpened for extended use, producing clean, smooth, and burr-free holes.

4. These metric forstner bits are ideal for boring holes in solid wood, cork, hardwood, plywood, medium-density fiberboard, particleboard, and even plastics, rubber, and other materials. They are compatible with a variety of drills, including handheld, bench, vertical, and CNC engraving machines, thanks to their standard shank diameter.

5. Not suitable for metalwork. Materials should be secured during cutting, with the bit perpendicular to the surface. For hardwood processing, water, oil, or lubricant can be applied to enhance drilling precision and quality.
