Ratio Drill with Oil Feed

	Type RT 100 C DIN 6537
Manufacturing specifications	Point grinding: relieved cone with secondary flank Point angle: greater than standard (140º) Web thinned: ratio web thinning form S Helix angle: normal Web thickness: greater than standard Web taper: smaller than standard Flute form: special Tolerance on diameter: m7 Oil feed: spiral through the body Shank: reinforced, with whistle notch flat, according DIN 6537 HE, h6 tolerance Other manufacturing specifications to DIN 6540.
Range of applications	High-performance drill for the drilling of carbon steels, structural and case hardened steels, unalloyed cast steels as well as heat-treatable steels with a tensile strength of up to approx. 850 N/mm˛. The specially conceived cutting point geometry produces a best possible chip fracture even with soft, long-chipping materials. Advantages, Suggestions Highest speed and feed rates possible (see Guroguide), high alignment accuracy with small diameter tolerance and excellent surface finish. Excellent self-centering qualities as well as producing short chips thanks to a concave cutting point geometry with special point grind and web thinning. Pre-conditions for use Powerful machines. No play in spindle bearings. Alignment accurate tool holders. Max. concentricity error of clamped tools: 0.02 mm. Chatterfree, mechanical feeds. The tools are available without whistle notch flat for the application in hydraulic chucks.
