Value Collection 01188424 No. 42 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188424 is a No. 42 wire-gauge jobber-length drill bit machined from high speed steel (HSS) with an oxide coating for added surface hardness and basic corrosion resistance. The bit features a 118-degree standard point angle, a regular spiral flute with a tapered web configuration, and a web-thinned tip that reduces thrust load at drill entry. Overall length is 2.25 inches with a 1.25-inch flute length. The straight cylindrical shank diameter matches the wire-size decimal equivalent of 0.0935 inches. This is a right-hand cutting bit suited for general-purpose drilling in steel, cast iron, and similar ferrous materials. Machinists, maintenance technicians, and fabricators install this style of bit in standard drill presses, hand drills, and CNC machines.

The No. 42 jobber drill is a standard general-purpose bit used across light manufacturing, maintenance and repair, and metal fabrication operations. Its compact 2.25-inch overall length suits close-tolerance work and benchtop drill press applications. Primary workpiece materials include steel and cast iron. The bit does not support coolant-through delivery, making it appropriate for conventional flood or mist cooling where required by the operation.

Key Features

• Wire size No. 42, decimal equivalent 0.0935 inches for precision hole sizing
• 118-degree standard point angle for general-purpose drilling in ferrous metals
• High speed steel construction provides hardness and wear resistance at elevated cutting temperatures
• Oxide coating adds surface hardness and provides basic lubricity
• Web-thinned tip with tapered web configuration reduces entry thrust and walking
• Regular spiral flute promotes chip evacuation during drilling operations

Compatibility

Designed as a general-purpose jobber-length drill bit for use in any standard drill chuck accepting a 0.0935-inch straight cylindrical shank, including benchtop drill presses, hand drills, and compatible CNC toolholders.

Installation Notes

This bit is installed and removed by a qualified machinist or technician using a standard Jacobs-style or keyless drill chuck rated for the shank diameter. Ensure the spindle is fully stopped and power is isolated before changing bits. Secure the shank fully into the chuck jaws to the depth recommended by the chuck manufacturer to prevent slippage and runout. Use appropriate cutting fluid or mist cooling when drilling ferrous materials to extend tool life and maintain hole quality.
