Chicago-Latrobe 47375 17.50mm HSS 118° Jobber Drill Bit

17.50 mm Jobber Drill Bit

The Chicago-Latrobe 47375 is a metric jobber length drill bit made from high speed steel with a black oxide finish. It is intended for general-purpose drilling in metal, wood and plastic where a 17.50 mm hole is required. The conventional 118 degree point angle suits a wide range of materials and standard drilling machines.

118 Degree Conventional Point

The 118 degree point angle provides reliable centring and chip evacuation in common ferrous and non-ferrous materials. It is not a split-point or self-centring geometry, so a centre punch mark is recommended for accurate hole placement on hard or smooth surfaces. The bit has no coolant-through holes and is not designed for internal coolant delivery.

17.5 mm Capacity and Headroom

The bit produces a 17.50 mm diameter hole, decimal equivalent 0.6890 inch, suitable for clearance or tapping operations at that size. High speed steel construction offers good wear resistance in mild steel and aluminium but will dull quickly in hardened alloys or abrasive composites. For larger diameters or production volumes, carbide tooling or a different drill geometry would be required.
