Irwin IR63914 Hss Jobber Drill Bit 7/32 in 135 Deg Split Point

Product Description

The IRWIN IR63914 is a high speed steel jobber-length drill bit with a titanium nitride (TiN) coating and a 135-degree split point. Designed for metal drilling applications in trade and industrial settings, this bit delivers consistent hole quality across a range of ferrous and non-ferrous materials. The 7/32-inch drill diameter, 2.5-inch flute length, and 3.75-inch overall length make it a standard jobber-length option. Hardness is rated at 80 HRC, and the split point geometry reduces walking at the start of a cut without requiring a center punch. Electricians, plumbers, HVAC technicians, and general contractors routinely use jobber-length bits like this for panel knockouts, conduit holes, and bracket installations.

This drill bit is suited for use in handheld drills, drill presses, and magnetic base drills on job sites and in shop environments. The jobber-length format fits standard 3-jaw chucks and is commonly used in both residential and light commercial construction for drilling through steel studs, brackets, sheet metal, and similar materials. The TiN coating extends tool life compared to uncoated HSS bits under sustained use.

Key Features

• 7/32-inch drill diameter for standard hole sizes in metal and wood substrates
• 135-degree split point reduces bit walking and eliminates the need for center punching in most applications
• Titanium nitride coating increases surface hardness and extends service life versus uncoated HSS
• 80 HRC hardness rating for durability under repeated use
• 2.5-inch flute length provides adequate chip clearance in jobber-length drilling tasks
• Jobber-length format fits standard 3-jaw drill chucks

Compatibility

Designed as a standard jobber-length HSS drill bit compatible with 3-jaw chucks on handheld drills and drill presses accepting a 7/32-inch shank.

Installation Notes

Secure the workpiece firmly before drilling to prevent movement and bit breakage. Use appropriate cutting fluid or lubricant when drilling hardened steel to reduce heat buildup and extend bit life. Always wear eye protection. Inspect the bit for chipping or wear before each use and replace if the cutting edges are damaged.
