It carries an 11\/64-inch drill diameter, a 135-degree split point for self-centering entry without a center punch, and a titanium nitride (TiN) coating that reduces friction and extends cutting life. The overall length measures 3.25 inches, with a flute length of 2.125 inches. Hardness is rated at 80 HRC, indicating a high-speed steel construction hardened for demanding production and service work. This bit is a standard choice for HVAC technicians, electricians, plumbers, and general trade professionals who drill pilot holes, mounting holes, and clearance holes in the field and in the shop.\u003c\/p\u003e\u003cp\u003eThe IR63911 fits standard 3-jaw drill chucks and is suited for both bench-mounted drill presses and handheld cordless or corded drills. Its jobber-length shank makes it practical for close-quarters work encountered in equipment rooms, electrical panels, and mechanical chases. The 135-degree split point geometry is particularly useful when drilling into harder steel, such as equipment housings, electrical enclosures, and strut channel, without the bit walking off-center.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point eliminates the need for a center punch and reduces walking on hard surfaces\u003c\/li\u003e\n\u003cli\u003eTitanium nitride coating lowers surface friction and increases bit longevity compared to uncoated HSS\u003c\/li\u003e\n\u003cli\u003e80 HRC hardness rating for durability in high-speed drilling applications\u003c\/li\u003e\n\u003cli\u003eJobber length at 3.25 inches overall provides versatility across drill press and handheld use\u003c\/li\u003e\n\u003cli\u003e2.125-inch flute length supports efficient chip evacuation during drilling\u003c\/li\u003e\n\u003cli\u003eSold individually, compatible with standard 3-jaw chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-length drill bit compatible with any drill press or handheld drill accepting a round-shank bit at the 11\/64-inch diameter size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the bit firmly in the drill chuck before operation and verify the chuck key is removed before starting the drill. When drilling metal, use appropriate cutting fluid or lubricant to reduce heat buildup and extend bit life. Always wear eye protection when drilling.
