Chicago-Latrobe 78704 Drill Bit

This Chicago-Latrobe 78704 screw machine drill bit has a 1/8 in size and a 118 degree point angle. It features a 4 facet point design made from carbide material with a bright uncoated finish. The decimal equivalent is .1250 and it cuts in a right hand direction. It is a non-coolant through type accessory.

Installation requires standard drill chuck

The bit installs into a compatible drill chuck by tightening the jaws securely around the shank. Ensure the chuck is clean for proper grip. The bright uncoated surface may require lubrication depending on the workpiece material. The 118 degree point angle is suited for general purpose drilling but may walk on very hard surfaces without a centre punch.

Check chuck capacity and material suitability

Verify your drill chuck accepts a 1/8 in shank diameter before ordering. Confirm the carbide construction matches the hardness of the material you intend to drill. The right hand cutting direction requires a standard clockwise rotation drill. This bit lacks coolant through holes so external cooling may be needed for deep holes.
