Value Collection 01248921 Hss Jobber Drill Bit 12.30mm

Product Description

The VALUE COLLECTION 01248921 is a high speed steel (HSS) jobber-length drill bit designed for general-purpose hole drilling in metalworking applications. It measures 12.30 mm (0.4843 inch) in diameter with an overall length of 149.00 mm (5.87 inches) and a flute length of 111.00 mm (4.37 inches). The 118-degree standard point angle is the industry-standard geometry for drilling into steel and cast iron. An oxide coating provides a layer of surface protection and helps reduce friction during cutting. This bit features a straight cylindrical shank and right-hand spiral fluting, making it compatible with standard drill chucks. It is used by machinists, pipefitters, ironworkers, and general trades.

This jobber drill bit is suited for drilling steel and cast iron in both shop and field environments. Its general-purpose grade and standard geometry make it appropriate for production drilling, maintenance work, and fabrication tasks where a reliable, mid-range HSS bit is required. The web-thinned, tapered web design reduces the thrust needed at the drill point, which is useful when drilling harder ferrous materials. It is sold individually and is sized within the 10.00 mm to 12.50 mm range class.

Compatibility

Designed for general-purpose drilling in steel and cast iron. Compatible with any standard drill press or handheld drill with a chuck capable of accepting a 12.30 mm straight shank.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with metal drilling procedures. Secure the workpiece and ensure the drill chuck is properly tightened before operation. Use appropriate cutting fluid or coolant when drilling steel to extend bit life and improve hole quality, noting that this bit does not support coolant-through delivery. Inspect the cutting edges for wear before each use and replace the bit if the point is chipped or burned.
