Chicago-Latrobe 78596 140° solid carbide drill

The Chicago-Latrobe 78596 is a straight-flute drill bit made from solid carbide. It targets machinists and maintenance technicians who need a rigid tool for short-hole drilling in hardened or abrasive materials.

Check shank fit and coolant setup

Verify that your toolholder or collet accepts a 3/16 inch shank before ordering. The bright uncoated finish and straight-flute design perform best with flood coolant or mist lubrication to evacuate chips from the 1 1/8 inch flute length.

Four-facet point changes starting behaviour

The 140-degree four-facet point is ground to self-centre without a pilot hole, reducing walk on flat surfaces. The uncoated carbide substrate keeps the edge sharp for regrinding, extending service life in repeat production runs.

Questions about this item

What comes in the box with the 78596 drill and is anything else needed to use it?

The box contains the 140° solid carbide straight flute drill bit itself; no extra components are included and no separate purchase is required to operate it in a compatible chuck.

Which version of the 78596 should I choose for a 3/16 in hole?

The 78596 is a single 3/16 in (0.1875 decimal) drill with a 140° point and 1 1/8 in flute length; there are no alternate diameters or lengths for this part number.

What does the 140° point angle mean when the 78596 is in a machine?

The 140° point with four-facet geometry centres the bit quickly in hard materials and reduces thrust, so the carbide drill starts cleanly and holds size in abrasive alloys.
