Value Collection 01243104 Jobber Drill Bit 3.10 Mm Hss

Product Description

The VALUE COLLECTION 01243104 is a high speed steel (HSS) jobber-length drill bit designed for general-purpose drilling in steel, cast iron, and similar ferrous materials. The bit features a 118-degree standard point angle with web thinning for easier center penetration and reduced walking on entry. An oxide coating provides mild lubricity and corrosion resistance during use. With an overall length of 2.75 inches and a flute length of 1.6094 inches, this bit fits standard drill chucks and benchtop or handheld drill presses used daily in trade and fabrication settings.

This jobber drill bit is suited for metalworking tasks in HVAC, plumbing, electrical, and mechanical trades where clean, accurate holes in ferrous stock are required. The 3.10 mm (0.1220 inch) diameter falls within the 3.00 to 4.00 mm size range, making it a practical choice for pilot holes, sheet metal work, and light structural drilling. The straight cylindrical shank seats securely in keyless or keyed chucks across standard drill presses and hand drills. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole operations.

Installation Notes

Install and service performed by machinists, pipefitters, electricians, or HVAC technicians using a bench drill press or handheld drill. Secure the shank fully in the chuck before operation and confirm the workpiece is clamped or fixtured. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is present.
