• Suited for tougher materials such as alloys, stainless manganese steels, etc.
• 135 Split point design is self-centering and helps to reduce the thrust requirements.
• Suited for heavy-duty, drilling operations.
• The 135 split point works for drilling alloy steels, manganese steels, harder stainless steels, and a variety of tough ferrous alloys.
• While cobalt drills generally offer a variety of benefits for drilling all materials, they are especially well suited for heavy duty operations in high tensile strength, low machinability, ferrous metals and alloys.
• May be used with hand held manual drills and either portable or stationary machines.
• Suitable lubricating/cutting oils or appropriate coolant fluids are recommended for most drilling operations to achieve optimal performance extended tool life.
• Jobbers length corresponds to the drill diameter. The jobbers length used for each of these drills is variable and determined by the specific drill diameter, offering the best balance between overall drill rigidity and depth capacity for each drill diameter.
