Chicago-Latrobe 43793 Drill Bit
This Chicago-Latrobe 43793 is a jobber length drill bit made from high speed steel with a TiCN coating. It is designed for general purpose drilling tasks where a durable, heavy-duty cutting tool is required. The split point design helps to reduce walking and improves starting accuracy on contact.
Suited for metal drilling with 135 degree angle
Machinists and maintenance technicians drilling into metal will find the 135 degree point angle effective for harder materials. The split point aids centring without a centre punch. Buyers needing coolant-through capability or a different point geometry should look at other tooling options.
0.3860 inch diameter with split point
The decimal equivalent diameter is .3860 inches, corresponding to letter size W. This specific dimension determines compatibility with the required hole specification. Verify the exact size needed for the application before ordering this bit.

Questions about this item
What size drill chuck or collet accepts the 0.3860 inch shank of the 43793 bit?
The 43793 has a 0.3860 inch decimal-equivalent shank; choose a chuck or collet that grips this diameter securely.
How do I start the 135-degree split-point 43793 bit without it walking, and what step do users often skip?
Centre-punch the workpiece first, then apply steady axial pressure — skipping the centre-punch lets the bit wander on hard material.
When should the TiCN-coated 43793 bit be replaced or re-sharpened?
Replace or re-sharpen when the split point no longer self-centres or when cutting edges show visible rounding after drilling abrasive alloys.
