Drills & Drill Bits

The 180°-point angle makes the DC118 Supreme ideal for plunging into inclined or round surfaces because the drill is guided quickly on the margins and centered accurately. At the same time, burr formation remains extremely low. The protective corner chamfer on the cutting edges protects against rapid wear, which significantly increases tool life compared to drills without a protective chamfer.

DrillMeister drill sleeves are available in 16, 25, and 32 millimeters in diameters for metric sizes and 3/4 inches and one inch for imperial sizes that fit the drill holders of the same sizes equipped in Swiss lathes. All drill sleeves have a threaded connecting port on the sleeve end for easy coolant hose connection.

The DMH drill head features a fracture resistant design that is suitable for applications that involve drilling holes through thin-walled sections of workpieces. In normal circumstances, thin walls tend to spring back on the drill after the drill pierces through and exits the hole.

Tungaloy America's DeepTri-Drill indexable gundrill series is easy-to-handle and capable of delivering outstanding performance, exceptional efficiency and stability in deep hole drilling.

The machining improvements are achieved by a special cutting drill contour with an added rear contour configuration that acts like a guide pad while the drill remains in the bushing, keeping the tool on location. Once the drill is in the cut, these guide pads continue to force the tool to cut a straight path for the remainder of operation.

In a field study on an aluminum cylinder head, the application of the extended drill was able to achieve a tool life of 2,000 parts per drill when machining holes of 8 mm diameter at 5,000 RPM in the cut and a feed rate of 1200mm/minute.

The drills are coolant-through, straight flute (G-drills), with emulsion or oil and coolant pressure of 145-580 PSI (10-40 bar). They are offered in cylindrical shank configuration and have a 120° point angle with tolerance of m7.
