  • Easy operation This extra-long wood drill bit adopts an optimized spiral chip flute design, which can automatically and smoothly export wood chips during the drilling process, effectively avoiding chip jamming drilling, greatly reducing operating resistance, and making you feel more labor-saving when performing deep hole operations. Combined with the ultra-long cutting edge, the drill bit can complete the deep drilling task at one time, without repeated advance and retreat, smooth and efficient operation, and is a powerful assistant for woodworking deep hole processing.
  • 150mm Drill Bits Designed for deep hole machining needs. The drill body is constructed from high-performance high-speed steel (HSS), which combines superior red hardness with wear resistance, ensuring a consistently sharp cutting edge during deep hole operations. The classic twist groove type is precisely ground, which can not only cut efficiently, but also achieve smooth and fast chip evacuation, effectively prevent chip blockage, and ensure the stability and efficiency of the drilling process.
  • Widely compatible It is perfect for wood, plastic, rubber, steel plate, spring steel, mold steel and other materials, without the need for frequent tool changes. It has been strengthened for difficult-to-machine metals such as automobile spring steel and mold steel, which is wear-resistant and high-temperature resistant, challenging high-hardness drilling tasks.
