Irwin IR63932 Hss Drill Bit 1/2 Inch Titanium Nitride

Product Description

The IRWIN IR63932 is a jobber-length, high-speed steel twist drill bit designed for drilling through metals, plastics, and wood in demanding trade and production environments. It carries a titanium nitride (TiN) coating that increases surface hardness to 80 HRC, reducing friction and extending service life compared to uncoated HSS bits. The 135-degree split point allows the bit to self-center on contact, eliminating the need for a center punch on most surfaces. At 1/2 inch in diameter with a 6-inch overall length and 4.5-inch flute length, this bit suits hand drills, drill presses, and magnetic base drills commonly used by electricians, plumbers, HVAC techs, and pipe fitters.

This bit is suited for jobsite and shop use where a 1/2-inch diameter hole is required in ferrous and non-ferrous metals, structural steel, pipe, conduit, and similar materials. The jobber-length geometry balances rigidity with reach, making it practical for general-purpose boring tasks in mechanical and electrical rough-in work. It fits any 1/2-inch or larger chuck.

Key Features

• Titanium nitride (TiN) coating increases surface hardness to 80 HRC for extended bit life
• 135-degree split point self-centers on contact, reducing walking without a center punch
• High-speed steel (HSS) construction withstands the heat generated during metal drilling
• Jobber-length proportions provide rigidity while allowing sufficient reach for most applications
• 4.5-inch flute length promotes efficient chip evacuation during deep drilling passes

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any 1/2-inch or larger keyed or keyless drill chuck on hand drills, drill presses, and magnetic base drills.

Installation Notes

Install and remove this bit with the drill unplugged or the tool battery removed. Secure the workpiece before drilling to prevent rotation. Use appropriate cutting fluid when drilling hardened steel or stainless to manage heat buildup. Follow applicable OSHA and site safety requirements for rotating tools and eye protection.
