Coolant-Fed Drills Enable Deep Drillling
Cobra Carbide’s Blackmamba series of coolant-fed drills are designed to enable drilling to a depth of eight times the tool diameter.
Cobra Carbide’s Blackmamba series of coolant-fed drills features a flute design and cutting edge geometry that enables drilling to a depth of eight times the tool diameter. The drills are said to feature enhanced self-centering characteristics, optimized chip flow, high cutting rates and high productivity. They also eliminate the pecking cycle, reducing drilling time compared to conventional drilling, the compan says.
Consider these alternatives when conventional drilling can't do the job.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
