Chicago-Latrobe 49724 Taper Length Bit
The Chicago-Latrobe 49724 is a general-purpose taper length drill bit manufactured from high-speed steel with a black oxide finish. It features a 118-degree radial point designed for conventional drilling tasks in a variety of materials. This tool suits machinists and maintenance crews needing extended reach for deep-hole applications. It arrives new and ready for immediate workshop use.
Best for deep holes, not precision starts
This bit suits operators drilling deep holes where the taper length provides necessary flute clearance and reach. The 118-degree point handles general-purpose materials effectively without specialised geometry. Buyers who need a split point for self-centring on hard surfaces or a different point angle for specific alloys should look at other tooling. The black oxide finish aids chip flow and reduces galling in steel.
118-degree radial point angle decides fit
The single specification determining suitability is the 118-degree radial point angle. This geometry is standard for general-purpose drilling in mild steel, cast iron and non-ferrous metals. If the application demands a flatter or steeper angle for hard steel, stainless steel or non-metallic composites, this bit will not perform correctly. Match the point angle to the workpiece material before ordering.

Questions about this item
How do I install the 3/8 in drill bit in my drill chuck, and what step do people often miss?
Open the chuck jaws wide enough, insert the shank fully until it seats against the back of the jaws, then tighten securely — the step many miss is fully seating the shank before tightening.
What maintenance or replacement will the high-speed steel bit with black oxide finish need later?
Resharpen the 118-degree radial point when cutting edges dull; the black oxide coating wears off over time and does not need replenishment.
What limit appears first during sustained drilling with the 118-degree point angle?
Heat buildup at the cutting edges reduces hardness and dulls the point fastest, especially in harder materials or without coolant.
