Value Collection 01189083 Letter H Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01189083 is a Letter H jobber-length drill bit designed for general-purpose drilling in steel, cast iron, and similar ferrous materials. Built from high speed steel (HSS) with an oxide coating for surface protection, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves penetration. The straight cylindrical shank measures 0.2660 inches in diameter, matching the Letter H decimal equivalent. A right-hand, regular spiral flute design clears chips efficiently during through-hole and blind-hole work. Machinists, fabricators, and maintenance technicians reach for this type of bit as a reliable everyday cutting tool.

This drill bit is suited for use in drill presses, lathes, and handheld power drills across light industrial, maintenance, and fabrication environments. Its general-purpose grade makes it appropriate for production and repair work where standard tolerances apply. The 2.875-inch flute length provides adequate chip clearance for most jobber-depth holes, and the 4.125-inch overall length fits standard drill chucks without modification. Primary workpiece materials include steel and cast iron.

Installation Notes

This bit is installed and removed by a licensed machinist or qualified technician following standard tooling procedures. Secure the shank fully in the chuck and confirm concentricity before operation. Use appropriate cutting fluid or coolant when drilling steel at higher feed rates to extend tool life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
