Value Collection 01166172 Letter Q Jobber Drill Bit Hss

Product Description

The VALUE COLLECTION 01166172 is a Letter Q jobber-length drill bit ground from high speed steel (HSS) with a bright uncoated finish. It cuts a 0.3320 inch diameter hole with a standard 118 degree split-point geometry and a web-thinned, tapered web configuration that reduces thrust on entry. The flute length runs 3.4375 inches and the overall length is 4.75 inches. The straight cylindrical shank seats directly in a standard drill chuck. General-purpose grade construction makes this bit suitable for production and maintenance drilling in a wide range of shop and field settings.

This bit is designed for drilling aluminum, non-ferrous metals, and other general-purpose workpiece materials. The two regular-spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling operations. It is a practical choice for HVAC techs, plumbers, electricians, and general tradespeople who need a reliable letter-size bit for panel knockouts, conduit entry points, bracket holes, and similar tasks. No coolant-through capability is required for the materials this bit targets.

Key Features

• Letter Q size — 0.3320 inch diameter for precise letter-series hole sizing
• 118 degree standard point angle with web-thinned tapered web reduces entry thrust

• Straight cylindrical shank fits standard keyed and keyless drill chucks

Compatibility

Designed as a general-purpose jobber drill bit compatible with any standard drill press, hand drill, or drill driver equipped with a chuck sized to accept a 0.3320 inch straight shank.

Installation Notes

Installation is performed by machinists, fabricators, and trade technicians using a drill press or portable drill. Secure the workpiece before drilling to prevent movement and ensure a clean hole. Match spindle speed to the workpiece material — lower speeds are appropriate for harder stock, higher speeds for aluminum and soft non-ferrous metals. Inspect the cutting edges before use and replace the bit if chipping or dulling is observed.
