The \"RT 100 T\" designation identifies this as a right-hand twist drill from Guhring's versatile Universal series, ground to DIN 1869 extra-long proportions with a black oxide steam-tempered surface treatment for improved corrosion resistance and lubricity. The drill features a standard cylindrical shank (reduced shank is not indicated), 118° point angle typical for this series, and is engineered for drilling steel, cast iron, aluminum, and non-ferrous metals across a wide range of materials — consistent with its \"Universal\" classification. Internal Guhring catalog number 6511-7.940 and item number 23944323 confirm this is a new, individually packaged unit (qty. 1) in the original Guhring clear plastic tube. Compatible with standard drill chucks and collet-style toolholders accepting a cylindrical shank in the 7.94 mm \/ 5\/16\" range.\u003c\/p\u003e\n\u003ch3
