2 RT 10 GG for cast iron facet point & new carbide grade deliver top performance in cast iron Available in 4xD, xd and 10xD lengths, the newest additions to Guhring s popular line of RT 10 GG coolant-through straightfluted carbide drills feature an aggressive, self-centering facet point and a new, more wear-resistant carbide grade. These design modifications deliver higher cutting speeds and longer tool life when machining short-chipping cast materials and other highly abrasive metals. KEY FEATURES: Aggressive, self-centering facet point. This point generates considerably less thrust and heat than conventional point styles. The combination of primary cutting lip and secondary heel clearance facets results in a naturally self-centering point. Performance enhancements include increased cutting edge life and accuracy. DK 2 F (K20) carbide. Developed in-house by Guhring, this carbide grade features a higher cobalt content than K grades, giving DK 2 F better wear resistance. This translates into significantly longer tool life, especially when machining abrasive materials such as cast iron. Rigid, straight-flute design. This design eliminates the spring effect coon with helical flutes and significantly increases tool rigidity. As a result, the RT 10 GG can be fed more aggressively, while delivering hole concentricity and straightness up to x better than standard HSS twist drills and up to 2x better than carbide twist drills. Double margin. Hole quality is further enhanced by the RT 10 GG s double margin effect, which provides minimal deviation from straightness and excellent self-centering performance. This feature enables the RT 10 GG to produce near-burnished hole finish, eliminating the need for secondary operations such as reaming or boring.

4 RT 10 GG/GN for aluminum 120 cone-relief point & super-tough carbide grade deliver top performance in aluminum Designed for accurate, high penetration rate holemaking in aluminum and high silicon-content aluminum, the original RT 10 GG is a soolant-through, straight-flute carbide drill that can achieve reamer-class hole quality (IT) when drilling from solid. Offered in 4xD, xd and 10xD lengths, the original RT 10 GG is now joined by a new negative-helix RT 10 GN version capable of drilling hole depths to 1xD. KEY FEATURES: Self-centering 120 cone-relief point. The steeper point angle results in a longer cutting edge, which improves the tool s selfcentering performance while delivering better hole straightness, especially in short-chipping materials such as aluminum and high silicon-content aluminum alloys. DK UF (K) carbide. This ultra-fine grain carbide was developed in-house by Guhring specifically for cutting tool applications and is 0-0% tougher than coon carbide grades. In particular, it delivers improved cutting edge strength and stability, preventing premature chipping and material loading. The ultra-fine grain size also allows tools to be given sharper cutting edges. Significantly improved tool life, better holemaking consistency and broader tool application are among the key benefits of DK UF. Rigid, straight-flute design. This design eliminates the spring effect coon with helical flutes and significantly increases tool rigidity. As a result, the RT 10 GG can be fed more aggressively, while delivering hole concentricity and straightness up to x better than standard HSS twist drills and up to 2x better than carbide twist drills. Double margin. Hole quality is further enhanced by the RT 10 GG s double margin effect, which provides minimal deviation from straightness and excellent self-centering performance. This feature enables the RT 10 GG to produce near-burnished hole finish, eliminating the need for secondary operations such as reaming or boring. Negative helix (RT 10 GN # 3). The negative helix increases the drill s dynamic stability, allowing greater holemaking depths while delivering optimum surface quality and dimensional accuracy.

6 Application recoendations Prerequisites for the application of RT10 GG/GN drills: Powerful machines No play in spindle bearings Alignment-accurate toolholders (Hydraulic or shrinkfit chucks recoended) Max. concentricity error of clamped tools 0.02 High coolant pressure Safety notice Pilot Holes Pilot holes are absolutely necessary when drilling >xd. If the tools are not properly supported, the centrifugal forces can break these long drills before they reach the workpiece surface. Operating speed should be kept below,000 RPM until the tool is securely inside the pilot hole. Short, rigid drills can be used to machine a pilot hole larger than the diameter of the RT 10 GG/GN drill. Pilot hole depth should be at least 1.xD. Alternatively, the drills themselves can be used to produce their own pilot holes. Cutting speed and feed must be reduced 30-% until the pilot depth is achieved.
