Value Collection 01189067 Letter F Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01189067 is a Letter F jobber-length drill bit ground from high speed steel (HSS) with a black oxide finish. It cuts a 0.2570-inch diameter hole and runs a standard 118-degree split-point angle suited for general-purpose drilling in steel, cast iron, and similar ferrous materials. The two-flute, regular spiral design clears chips efficiently during through-hole and blind-hole operations. Web thinning at the tip reduces thrust load and helps the bit self-center without a pilot hole. At 4.125 inches overall with a 2.875-inch flute length, this is a standard jobber reach for most bench, drill-press, and handheld operations encountered in metalworking and fabrication shops.

This drill bit is intended for right-hand rotation and is sold as a single piece, with a minimum order of six units. It suits production and maintenance shops that drill steel plate, cast iron housings, structural members, and similar workpieces at moderate speeds. The straight cylindrical shank fits standard 3-jaw chucks across drill presses, milling machines, and hand drills without requiring a collet or adapter. General-purpose grade designation makes this bit appropriate for everyday shop work rather than specialty alloy or hardened-material applications.

Key Features

• Letter F diameter: 0.2570 inches for close-tolerance layout and tapping prep
• 118-degree standard point angle with web thinning for reduced entry thrust
• High speed steel construction handles moderate heat generated in steel and cast iron
• Black oxide coating provides light corrosion resistance and reduces friction at the cutting edge
• Regular spiral, two-flute design promotes efficient chip evacuation
• Straight cylindrical shank seats directly in standard 3-jaw chucks

Compatibility

Designed as a general-purpose jobber drill bit for use in drill presses, milling machines, and handheld drills equipped with a standard 3-jaw chuck accepting a 0.2570-inch straight shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists, maintenance technicians, or trade professionals familiar with rotating cutting tools. Secure the workpiece firmly before drilling and confirm the chuck is fully tightened on the shank. Select cutting speed appropriate for the workpiece material and bit diameter per standard machining references; excessive speed generates heat that degrades HSS tooling. Always wear appropriate eye protection and follow shop safety protocols when operating drilling equipment.
