Gühring 304198259 40mm HSS Stiftlochbohrer 495x355mm Taper Shank Drill Bit

This is a new Gühring Stiftlochbohrer (pin-hole/stub-bore twist drill) in 40.0 mm diameter, catalog number 304198259, with serial/order reference 23563739 and tool serial 23571113, manufactured in Germany. The drill is constructed from HSS (High Speed Steel) with a black oxide surface treatment visible on the flute body, providing corrosion resistance and reduced friction during entry. Total length is 495 mm with a flute/cutting length of 355 mm, as labeled on the packaging, making it suitable for deep-bore applications in steel, cast iron, and similar ferrous workpiece materials. The taper shank (Morse taper, consistent with DIN 345 standard for 40 mm diameter drills — MT5) allows direct mounting in machine spindles, tailstocks, or taper-shank drill chucks on radial arm drills, floor-standing pillar drills, and horizontal boring mills. The tool is unused and stored in its original Gühring protective tube/container.
