The two flute gundrill design incorporates two cutting edges which reduces chip load and increases penetration rate up to 100% over single flute drills in various nonferrous applications. They can be used in conventional gundrilling machines and in CNC lathes and machining centers.
Two flute gundrill features include:
• Sub-micro grain carbide tips for greater tool life
• 4135 aircraft grade shanks
• Dual oil holes for optimum chip evacuation
| Solid carbide tip with tube (shank) manufactured from 4135 aircraft grade tubing. Diameters available from .375" (4.75mm) to .6299 " (16mm) and lengths to 84" (2133mm) |
 |
These tools are run under the same princeples as the crimped two flute drill, but offer a milled tube (shank), which allows higher penetration rates. They are usually applied to special applications, such as intersecting holes or when extremely high penetration rates are required.
| Solid carbide tips with a tube (shank) are manufactured from solid steel construction. The flutes are milled, resulting in a very rigid tool. Diameters available from .375" (9.525mm) to .6299 " (16mm) and lengths to 36" (914mm) |
