Guhring 6068-3.800 3.8mm WN R-RTG Ratiobohrer Solid Carbide Straight Flute Drill

The Guhring No. 6068-3.800 is a new 3.8 mm diameter Ratiobohrer ("ratio drill") — Guhring's proprietary series of carbide-tipped straight-flute drills optimized for short-hole drilling in cast iron, non-ferrous metals, and other materials where a straight-flute geometry provides superior chip control and rigidity over spiral designs. The label designation WN R-RTG identifies this as a right-hand cutting (R), straight-flute (WN) drill with Guhring's RTG (Ratio-Tip Geometry) carbide tip brazed into a steel body, delivering the wear resistance of solid carbide at the cutting zone with the toughness of a steel shank — confirmed by the two-tone appearance visible in the product photo, where the silver steel body transitions to the uncoated carbide tip at the cutting end. The Ø 3.8 25 marking on the label confirms the 3.8 mm cutting diameter and indicates a 25 mm flute/cutting length; the cylindrical shank is sized to suit standard collet chucks or drill chucks accepting 3.8 mm (or nearest standard) shanks. This drill is new, unused, and sourced directly in its original Guhring packaging (K 20699765 batch code), making it suitable for precision hole-making operations on machining centers, CNC drills, or conventional drill presses.
