USER GUIDE Single Flute Gundrill ISCAR's gundrill consists of a single piece carbide head, a streamlined shank and a driver through which coolant flows to the working end where it is most needed. Chips are evacuated along the V-shaped external flute. Carbide Tipped Gundrill Range Drill Diameter 2.50 to 3.09 3.10 to 5.99 6.00 to 11.39 11.40 to 40.00 Max. Flute Length 1100 2500 3000 3500 Drilling Head The carbide head is tapered on its length to reduce friction. The taper angle depends on the type of material to be drilled. For high precision drilling, the taper should be reduced to a minimum Note that when the head is resharpened, the diameter of the drill changes, affecting the hole tolerance. Overall length=flute length+driver length Shank The cross-section of the shank is V-shaped with coolant holes. It is made of hardened steel that is highly resistant to twisting (for information on carbide shanks, see next page). This crosssection provides the optimal conditions for twist resistance, coolant flow and chip evacuation. Driver Driver The driver ensures the connection between the gundrill and the machine tool. Shank Drilling Head Advantages • Drilling precision of IT7 to IT9 tolerances can be reached. • Excellent straightness and concentricity. • Maintains high precision hole center alignment. • Surface roughness of R 0.4-1.6mm is easily obtained. • Reboring operations are often unnecessary. ISCAR’s advanced gundrill technology provides superior geometric and dimensional quality for both deep and shallow drilling. The drills are available in the range of 2.5 to 40mm. C14 ISCAR

USER GUIDE ISCAR Single Flute Solid Carbide Gundrills Another type of gundrill is made with integral tip and shank, made of solid carbide with either a steel or a carbide driver. These drills are designed for conventional machines, machining centers and lathes. This style of gundrill is available from 0.9-16.00mm and can be used on various types of materials. It provides superior rigidity and optimal coolant flow rates. As a result of its rigidity, up to 100% higher feed rate can be reached. When using the small diameter drills, it is crucial to adhere closely to recommended drilling parameters. Solid Carbide Gundrill Range (with or without brazed steel driver) Drill Diameter 0.9 to 16.00 Max. Flute Length 300 Standard Gundrill Head Sharpening Angles Subject to the required tolerance, cutting performance and desired chip shape, the following standard sharpening angles are recommended (shown in figures 1-3).
