Westward 4UL57 19/64" HSS Black Oxide 118° Jobber Drill Bit

Precise 19/64" Jobber Drill Bit

The Westward 4UL57 is a fractional-inch jobber drill bit sized at 19/64 inch with a decimal equivalent of 0.2969. It suits machinists and maintenance technicians who need a specific intermediate diameter for general-purpose drilling in metal, wood or plastic.

High-Speed Steel with Black Oxide Finish

Constructed from high-speed steel, the bit resists wear during repetitive use while the black oxide coating reduces friction and helps retain lubricant. The conventional 118-degree point centres quickly without a pilot hole, and the jobber-length flute clears chips efficiently in handheld or press operations.

Replaces Worn or Undersized Bits

This bit replaces dull, chipped or undersized drills when a precise 19/64-inch hole is required for tap clearance, bolt fitting or reaming preparation. The jump is worthwhile when existing bits no longer hold tolerance or when a fractional step between standard sizes eliminates the need for secondary reaming.
