Value Collection 01188077 No 7 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188077 is a No. 7 wire size jobber-length drill bit ground from high speed steel and finished with an oxide coating for improved lubrication and heat resistance during drilling. The bit measures 3.625 inches overall with a 2.4375-inch flute length and a 0.2010-inch diameter. The 118-degree standard point angle is suited for general-purpose drilling in a wide range of common shop and field applications. Two regular spiral flutes evacuate chips efficiently, and the tapered web with web thinning reduces thrust and walking at the start of a cut. Licensed tradespeople and journeymen machinists are the typical installers of this tooling.

This jobber drill bit is intended for right-hand rotation in standard drill presses, hand drills, and CNC machines used in maintenance, fabrication, and repair work. Primary workpiece materials include steel and cast iron. The straight cylindrical shank accepts standard three-jaw chucks without modification. Coolant-through capability is not available on this bit, making it appropriate for light- to medium-duty applications where flood or through-tool coolant is not required.

Key Features

• No. 7 wire size, 0.2010-inch diameter for precise fractional and wire-gauge drilling
• 118-degree standard point angle with web thinning reduces entry thrust and improves centering
• High speed steel construction provides hardness and wear resistance across general-purpose materials
• Oxide coating acts as a mild lubricant and provides corrosion resistance during storage
• Regular spiral flute geometry promotes efficient chip evacuation in steel and cast iron
• Straight cylindrical shank fits standard three-jaw chucks on handheld and bench-mounted equipment

Compatibility

Designed as a general-purpose replacement or stock jobber drill bit for use in any right-hand drill press, cordless or corded hand drill, or CNC spindle equipped with a standard three-jaw chuck sized to accept a 0.2010-inch straight shank.

Installation Notes

Installation and use should be performed by qualified machinists, maintenance technicians, or tradespeople familiar with rotating cutting tool safety. Secure the shank fully in the chuck and confirm concentricity before beginning a cut. Always wear appropriate eye protection and ensure the workpiece is properly clamped or fixtured before drilling. Do not exceed the recommended speed and feed ranges for the workpiece material and bit diameter.
