Chicago-latrobe 68911 Jobber Drill Bit 11/64 in Hss

Product Description

The CHICAGO-LATROBE 68911 is a jobber-length drill bit designed for precision drilling in steel alloy and similar ferrous materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this bit features a 135-degree split point that reduces walking and allows drilling to begin without a center punch in many applications. The parabolic flute geometry promotes aggressive chip evacuation, reducing heat buildup and extending tool life in production and maintenance drilling environments. At 3.25 inches overall length and 11/64 inch diameter, it fits standard drill chucks and is suited for use in handheld drills, drill presses, and magnetic base drills.

The 68911 is appropriate for drilling steel alloy in residential, commercial, and light industrial settings. Its heavy-duty grade and web-thinned, tapered web construction make it a practical choice for HVAC technicians, plumbers, electricians, and general tradespeople who drill sheet metal, structural steel, and mechanical assemblies as part of routine installation or fabrication work. The straight-cylindrical shank seats securely in both keyed and keyless chucks across a wide range of drill equipment.

Key Features

• 135-degree split point reduces bit walking and improves starting accuracy on flat and curved metal surfaces
• Parabolic flute design accelerates chip removal and reduces heat in the cut zone
• High-speed steel construction provides toughness and wear resistance for ferrous materials
• Web-thinned, tapered web lowers thrust requirements and eases penetration in heavy-duty drilling
• Bright uncoated finish maintains consistent diameter tolerance of -0.0007 to 0.0000 inches
• Straight-cylindrical shank is compatible with standard keyed and keyless drill chucks

Compatibility

Designed as an OEM-style replacement or direct-use jobber-length drill bit within the CHICAGO-LATROBE Series 150DH line, suitable for drilling steel alloy and comparable ferrous materials in the 0.1500 to 0.2000 inch diameter range.

Installation Notes

Installation of this drill bit should be performed by qualified tradespeople familiar with rotary cutting tools and applicable shop or jobsite safety practices. Always power down and secure the drill or drill press before changing bits, and confirm the shank is fully seated and the chuck is tightened before operation. Use appropriate cutting fluid or lubricant when drilling steel alloy to extend bit life and improve hole quality. Wear appropriate eye protection in accordance with jobsite safety requirements.
