Irwin IR60520 Hss Jobber Drill Bit 5/16 Inch

Product Description

The IRWIN IR60520 is a high speed steel jobber-length drill bit with a 5/16-inch diameter and a standard 118-degree point angle. Built from HSS material with a straight shank, it is designed for general-purpose drilling in metal, wood, and plastic. The overall length is 4.5 inches with a flute length of 3.1875 inches. This bit is sized and proportioned for use in hand drills, drill presses, and cordless drivers across a wide range of trade and light industrial applications. Electricians, plumbers, HVAC techs, and general contractors keep jobber-length bits like this in regular rotation for everyday hole-making tasks.

The IR60520 is suited for residential and light commercial work where a versatile, mid-length drill bit is needed. Its jobber-length proportions make it compatible with standard 3-jaw chucks on both corded and cordless tools. The 5/16-inch diameter is a common size for anchor bolt clearance holes, conduit knock-out prep, and through-hole work in sheet metal and wood framing. Sold individually, it fits easily into existing bit sets or works as a direct replacement for a worn or broken bit of the same size.

Key Features

• 5/16-inch drill diameter for a widely used trade size
• 118-degree standard point angle for general-purpose material entry
• HSS construction provides heat resistance during extended drilling
• Jobber length at 4.5 inches overall balances reach and rigidity
• Straight shank fits standard 3-jaw chucks without adapters

Compatibility

Designed as a standard jobber-length HSS drill bit compatible with any power drill, drill press, or cordless tool equipped with a 3-jaw chuck accepting a straight-shank bit.

Installation Notes

Ensure the drill or driver is powered off and the bit is fully seated and tightened in the chuck before use. Use appropriate cutting speed for the material being drilled and apply consistent feed pressure to avoid overheating the bit. Eye protection and work-holding appropriate to the material are standard practice. Replace the bit if the cutting edges show signs of glazing or the point angle is worn.
