Precision Twist Drill 5999284 No. 68 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5999284 is a jobber-length drill bit in wire gauge size No. 68, equivalent to 1/32 inch (0.0310 inches decimal). Built from high speed steel (HSS) with a bright, uncoated finish, it features a standard 118-degree point angle and a regular spiral flute with right-hand cut. The two-flute design clears chips efficiently during through-hole and blind-hole drilling operations. Overall length is 1.375 inches with a flute length of 0.5 inches. This bit belongs to the R18P series and conforms to ANSI standards. It is suited for general-purpose drilling in a wide range of materials encountered in machining, fabrication, and maintenance work.

This bit is intended for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The small diameter makes it well suited for precision hole work, pilot holes, and fine drilling tasks in tool-and-die, sheet metal, electronics assembly, and general machining environments. Maximum drilling depth is 0.5 inches. The straight cylindrical shank fits standard drill chucks across benchtop drill presses, CNC machines, and handheld power tools. No coolant-through capability is required for general-purpose use at this diameter.

Key Features

• Wire gauge No. 68 size, 1/32 inch diameter (0.0310 inches decimal)
• High speed steel construction for general-purpose durability across multiple material types
• 118-degree standard point angle with web-thinned, tapered web geometry for easier starting
• Right-hand spiral flute promotes efficient chip evacuation during drilling
• Bright, uncoated finish provides consistent surface finish and dimensional accuracy
• Conforms to ANSI standards; R18P series designation

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 1/32-inch straight cylindrical shank. Suitable for use in handheld power drills, benchtop drill presses, and CNC drilling applications.

Installation Notes

Installation and use of this bit should be performed by machinists, fabricators, or qualified trade professionals familiar with rotating cutting tools. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before beginning any drilling operation. At this small diameter, reduce feed pressure to avoid bit deflection or breakage, particularly in hard materials. Always wear appropriate eye protection and follow applicable shop safety guidelines when operating drilling equipment.
