Material: Made of high-speed steel 6542, with higher hardness and good wear resistance, impact resistance and heat hardening, and is suitable for cutting workpieces with larger size and heavier load.
Polished Surface: The gold polished surface treatment enhances the twist drill's improved corrosion resistance, reducing friction during drilling operations and promoting smoother chip evacuation, minimizing heat generation, and enhancing overall drilling efficiency.
Features: Can take into account a variety of models, hand drill, percussion drill, lithium drill, and bench drill can be adapted, effectively for precision drilling tasks on various workpieces.
Applications: Jobber drill is used for drilling through hard materials such as stainless steel, alloy steel, cast iron, aluminum, copper, wood, malleable iron, aluminum, plastic, and other metals commonly encountered in machining applications.
Note: Use proper speed, pressure, and heat control when using these drill bits to maintain efficiency. In the drilling process, the appropriate use of cutting fluid or oil for cooling and lubrication, to extend the service life of the drill.
