Frequently asked questions
Common questions about PAN AMERICAN TOOL from 3G Electric.
What is the difference between Pan American Tool double margin drills and standard jobber drills?
Pan American Tool double margin drills feature two additional margins along the flutes, which provide more contact points with the hole wall. This design can improve hole straightness, finish, and dimensional accuracy compared to standard jobber drills, which typically have a single margin. The double margin also helps reduce vibration and deflection during drilling, particularly in tough materials. These drills are classified under NAS 907 Type J and have a 135° split point for reduced thrust and accurate starts. They are available in various sizes, including wire gauge, letter, fractional, and metric.
What materials are Pan American Tool cobalt jobber-length drill bits suitable for?
Pan American Tool cobalt jobber-length drill bits are suitable for drilling in a range of materials, including stainless steel, titanium, Inconel, and other high-strength alloys. The cobalt construction provides hot hardness, allowing the drills to maintain cutting edges at elevated temperatures. The 135° split point and straw/bronze finish further aid in chip evacuation and reduce friction. These drills are commonly used in aerospace, automotive, and general engineering applications where precision holemaking is required. They are not recommended for drilling in wood or plastics, as the geometry is optimized for metal cutting.
What does NAS 907 Type J mean for Pan American Tool drill bits?
NAS 907 Type J is a specification that defines requirements for high-speed steel and cobalt drills used in aerospace and general engineering. It covers dimensions, tolerances, and performance criteria. Pan American Tool double margin drills meet this standard, ensuring they are suitable for applications where compliance with NAS 907 is required. This classification provides assurance that the drills have been manufactured to specific quality and dimensional standards. It is not a certification but a standard that the products are designed to meet. Buyers should verify that the specific part number meets their application requirements.
What sizes of Pan American Tool double margin drills are available?
Pan American Tool double margin drills are available in a variety of sizes, including wire gauge numbers (#19, #8, #10, #40, #13), fractional sizes (1/8", 5/16"), and letter sizes (Letter D). Other sizes may be available upon request. Each size has a specific manufacturer part number, such as 13-DM19 for #19, 13-DM65 for 1/8", 13-DM08 for #8, 13-DM10 for #10, 13-DM40 for #40, 13-DM13 for #13, 13-DM77 for 5/16", and 13-DM93 for Letter D. The catalog lists these sizes with their respective specifications. For sizes not listed, contact 3G Electric for availability.
How does the straw/bronze finish on Pan American Tool drills affect performance?
The straw/bronze finish on Pan American Tool drills is a result of the heat treatment process, not a coating. It indicates that the tool has been processed to achieve the desired hardness and toughness. This finish can aid in chip flow and provide some resistance to wear and galling. It is not a lubricant, but it can help reduce friction between the drill and the workpiece. The finish is typical for cobalt drills and does not affect the dimensional accuracy. It is a visual indicator of the tool's metallurgical condition.
Can Pan American Tool double margin drills be used in CNC machining centers?
Yes, Pan American Tool double margin drills are suitable for use in CNC machining centers. The 135° split point and double margin design help with self-centering and reduce the need for spot drilling in many applications. They can be used in both rotating and stationary applications, depending on the machine setup. The cobalt construction allows for higher cutting speeds and feeds compared to standard high-speed steel drills. However, users should follow recommended speeds and feeds for the specific material being drilled. Proper coolant usage is also recommended to maximize tool life.
