Chicago-Latrobe 77647 Carbide Jobber Drill
This 5/32 inch jobber-length drill bit features a 118-degree conventional point and carbide-tipped construction. The bright uncoated finish suits general-purpose drilling in ferrous and non-ferrous materials. Decimal equivalent is 0.1563 inch for precise hole sizing.
Suited for abrasive materials.
Carbide tips resist wear when drilling cast iron, composites or hardened steel where high-speed steel dulls quickly. The 118-degree point centres easily without a pilot hole. Shops needing coolant-through capability or coated bits for extended life in stainless steel should consider other tooling.
118-degree carbide-tipped point defines
The conventional 118-degree point angle provides reliable self-centring in rigid setups. Carbide construction allows higher cutting speeds in abrasive alloys but is more brittle than cobalt or coated high-speed steel. Match the point geometry and substrate to the workpiece material and machine rigidity.

Questions about this item
Which drill bit size should I choose for a 5/32 inch hole?
This bit is sized at 5/32 in with a decimal equivalent of .1563, so it matches that exact diameter.
What does the 118 degree point angle mean when drilling?
The 118 degree conventional point is a general-purpose geometry that centres well in steel, cast iron and other common metals.
How does the carbide tip affect drilling in hard materials?
The carbide tip resists wear and holds its edge longer than high-speed steel when cutting abrasive or hardened workpieces.
