Holzbohrer

Holzbohrer, or wood drill bit, is a cutting tool designed to bore holes into wood. They are used with hand drills or powered drill systems and come in several geometries optimized for wood cutting. Typical Holzbohrer are made from high-speed steel, carbon steel, or carbide-tipped steel, and may be coated to improve wear resistance. The choice of bit depends on hole size, edge quality, and the wood type.

Common wood-specific drill bits include twist bits for general-purpose drilling, brad-point bits designed for accurate positioning and clean-edged holes, auger bits for fast drilling of larger holes, and Forstner bits for flat-bottom holes with smooth edges. Spade bits are used for rough, large-diameter holes. For very large holes, hole-saw bits are used in combination with a pilot bit. Each type has particular advantages: brad-point bits preserve the hole outline in wood, auger and twist bits differ in speed and chip removal, and Forstner bits produce precise, flat-bottom recesses suitable for dowels or hinge mortises.

Materials and construction vary: many Holzbohrer are made from high-speed steel, some are carbide-tipped for longer life, and others are carbon steel for inexpensive, light-duty work. Coatings such as black oxide or titanium nitride can reduce wear and heat buildup.

Usage and care involve selecting the appropriate bit for the wood and hole diameter, drilling at suitable speeds, and applying steady, moderate pressure. Keeping bits sharp and cool, removing chips regularly, and securing the workpiece are important for accuracy and safety. Proper storage helps prevent rust and dulling.
