Industrial 25025S-125L Indexable Spade Drill Bit

Allied Machine & Engineering's 25025S-125L is an indexable spade drill insert holder in the 2.5 Series, engineered for through-coolant holemaking in metal with a cutting range from 1-3/16" to 1-3/8" in diameter and a straight-flute geometry that aids chip evacuation and hole quality. It uses replaceable inserts as part of its indexable spade design and features a 1-1/4" shank, a body length of 12-41/64" (12.6406"), and a total length of 16" with a maximum drilling depth of 11-3/8". Through-coolant capability is implemented via an internal coolant passage and a 1/8" NPT coolant hole threaded through the body. The 2.5-series tool is documented for multiple primary workpiece materials, including codes H, K, M, N, P, and S, making it suitable for drilling in a range of common metals.
