Value Collection 01220110 Left Hand Jobber Drill 11/64 in

Product Description

The VALUE COLLECTION 01220110 is a left-hand jobber-length drill bit ground from high speed steel (HSS) for general-purpose drilling applications. It measures 11/64 inch (0.1719 inch) in diameter with a standard 118-degree point angle and a bright, uncoated finish. The bit features a regular spiral flute and a straight cylindrical shank. Overall length is 3-1/4 inches with a flute length of 2-1/8 inches. Left-hand cutting direction makes this bit well-suited for reverse-rotation operations, commonly used to back out broken fasteners or extract damaged studs without additional tooling.

This bit is used in metalworking, maintenance, and mechanical service environments where left-hand rotation is required or advantageous. Typical applications include extraction of broken bolts, sheared screws, and seized fasteners in metal substrates. It is sized for use in standard drill chucks that accept a straight shank. The general-purpose HSS construction handles steel, aluminum, brass, and similar materials at moderate cutting speeds. It is sold individually and is appropriate for use by machinists, maintenance technicians, HVAC service techs, and plumbers working with metal components.

Key Features

• Left-hand cutting direction for reverse-rotation drilling and broken fastener extraction
• 11/64 inch (0.1719 inch) diameter with matching straight cylindrical shank
• 118-degree standard point angle for general-purpose entry into metal
• Regular spiral flute with tapered web and web-thinned geometry for improved chip evacuation
• Bright, uncoated HSS finish — no coating to chip or peel during regrinding
• 3-1/4 inch overall length with 2-1/8 inch flute length for jobber-standard reach

Compatibility

Designed as a general-purpose left-hand jobber drill bit compatible with any standard drill chuck accepting a straight cylindrical shank sized at 0.1719 inch diameter.

Installation Notes

Left-hand drill bits require a drill or driver set to reverse rotation before use. Secure the workpiece firmly before drilling to prevent movement. Use cutting fluid on harder metals to extend bit life and reduce heat buildup. Regrinding is possible given the uncoated HSS construction — follow standard drill grinding procedures.
