Chicago-latrobe 68930 Jobber Drill Bit 15/32 Inch Hss

Product Description

The CHICAGO-LATROBE 68930 is a jobber-length drill bit designed for heavy-duty drilling in steel alloy and similar ferrous materials. Built from high speed steel with a bright uncoated finish, it measures 15/32 inches (0.4688 inches decimal) in diameter with a 5-3/4 inch overall length. The 135-degree split point reduces walking on entry and lowers the thrust force needed to start a hole. The parabolic flute geometry evacuates chips efficiently, which is especially important in deeper holes and gummy materials. This bit is a workhorse for machinists, ironworkers, pipefitters, and general fabrication tradespeople who need consistent, accurate holes in structural and alloy steels.

The 68930 fits standard jobber-length drilling applications in fabrication shops, mechanical rooms, and field service environments. Its straight cylindrical shank seats in any standard three-jaw drill chuck, making it compatible with handheld drills, drill presses, and magnetic base drills. The Series 150DH designation places it in CHICAGO-LATROBE's heavy-duty line, intended for production and repetitive-use scenarios where a general-purpose bit would wear prematurely. Right-hand cut geometry is standard for all conventional drilling equipment.

Key Features

• 135-degree split point reduces walking and lowers entry thrust on hard materials
• Parabolic flute design improves chip evacuation in deep holes and alloy steels
• High speed steel construction rated for heavy-duty Series 150DH service
• Web-thinned, tapered web reduces cutting resistance and heat buildup
• Straight cylindrical shank fits standard drill chucks without adapters
• Right-hand cut, 2-flute configuration suits conventional drilling equipment

Compatibility

Designed for drilling steel alloy as the primary workpiece material. The straight cylindrical shank fits any standard three-jaw drill chuck accepting a 15/32-inch shank. No specific OEM equipment compatibility was provided by the manufacturer for this SKU.

Installation Notes

Install this bit in a properly tightened drill chuck before applying power. Secure the workpiece firmly before drilling to prevent rotation or movement. Apply cutting fluid or coolant when drilling alloy steels to extend bit life and maintain tolerance. Inspect the cutting edges for wear or chipping before each use, and replace the bit if the split point or flute edges are damaged to avoid out-of-tolerance holes.
