📋 目次
1What flute length do I need for my drilling depth?
For most woodworking, a flute length 1.5 to 2 times the bit diameter is ideal. For example, a 12mm bit should have a flute length of 18–24mm to allow full chip evacuation when drilling deep holes in hardwoods or MDF.
2Are carbide Forstner bits worth the extra cost over high-speed steel?
Yes — carbide bits last 5–10 times longer and cut cleaner in hardwoods, laminates, and composites. They stay sharp longer at high speeds, making them ideal for production work or frequent use, though they’re slightly more brittle than HSS in impact-heavy jobs.
3What arbor size should I look for in a carbide Forstner bit?
Most bench-mounted Forstner bits use a 1/2” arbor, but 8mm and 1/4” options exist for smaller routers. Ensure your router or drill press can accommodate the arbor size before purchasing, especially if you plan to use the bit in a handheld tool.
4How do I know if a Forstner bit is suitable for through or blind holes?
Bits with a full cutting edge and a center point are best for through holes, while those with a raised center or a smaller cutting edge are better for blind holes. Look for a bit with a beveled edge or a shallow center cut for clean, flat-bottomed recesses in veneers or cabinetry.
5What are the most common mistakes when using carbide Forstner bits?
Overloading the bit by drilling too deep in one pass can cause overheating and dulling. Always use light pressure and let the bit do the work. Also, avoid using them in softwoods like pine at high speeds, as they can burn or tear the wood surface.
