High Speed Steel TMX Taper Shank Core Drill. HSS Taper Shank 4 Flute TMX Core Drill, 1-17/32" cutting diameter x 9-3/8" flute length x 16-3/8" overall length (OAL) with # 5 MT shank. Core drills can enlarge a hole up to 40% of it's original diameter

Large size general-purpose drills with three-flatted 1/2" reduced shank. Manufactured from high-speed steel substrate. 118° split point for easier, more precise penetration. Standard 6" overall length and 3-1/8" flute length for increased rigidity, less deflection and better hole accuracy. Standardized lengths result in minimal adjustment during tool changes in screw machines and machining centers. Three flats on shank for a more positive grip in the drill chuck; flats reduce drill slippage under high loads. Ideal for portable drilling due to increased rigidity. Black and gold ...

The shorter length provides extra rigidity and strength in tough materials. They are ideal for Bridgeport, and hand-held applications. Includes: 5/8" Reamer 11/16" Reamer 3/4" Reamer 13/16" Reamer 7/8" Reamer 1" Reamer Wood Block
