Chicago-Latrobe 49731 Taper Length Drill Bit
This Chicago-Latrobe 49731 drill bit is a general-purpose cutting tool manufactured from high-speed steel with a black oxide finish. It is designed for machinists and maintenance technicians who require a longer flute length for deeper hole drilling in metal, wood, or plastic.
118 Degree Radial Point Geometry
The 118-degree radial point angle is a standard geometry suited for a wide range of materials but is not specialised for hard alloys or high-performance drilling. Its taper length design provides extended reach compared to jobber-length bits, though it lacks the rigidity of shorter stub-length alternatives for precision work.
31/64 Inch Diameter Specification
The drill bit diameter is exactly 31/64 inch, which determines the final hole size and tap compatibility for the application. Buyers needing a different fractional size, metric equivalent, or a split-point design for reduced walking must select a different part number.
Highlights
- 31/64 in diameter drills precise holes
- 118-degree point angle centres quickly on contact
- Radial point geometry improves chip evacuation
- High-speed steel construction resists heat buildup
- Black oxide finish reduces friction and wear

Questions about this item
Should I choose the 31/64 in size or a different drill bit diameter?
Select the 31/64 in diameter when your project requires that exact hole size; other diameters are separate items.
What does the 118 degree point angle mean when drilling?
The 118 degree point angle is a general-purpose geometry suited for drilling mild steel, aluminium and similar materials in a standard machine.
Does the taper length shank fit a standard drill chuck or a taper socket?
The taper length shank is designed for a Morse taper socket; it will not grip securely in a standard three-jaw drill chuck.
