Chicago-latrobe 69015 Jobber Drill Bit Size 15 Hss 135 Degree

Product Description

The CHICAGO-LATROBE 69015 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, this bit features a 135-degree split point that reduces walking and requires no center punch on flat surfaces. The parabolic flute geometry clears chips aggressively, reducing heat buildup and improving feed rates in deep-hole applications. At 0.1800 inches in diameter (wire gauge size 15) with a 3-3/8 inch overall length, this bit fits standard drill chucks and is well suited for production or service work where consistent hole quality matters. Licensed trades and metalworking shops are the primary installers.

This bit is rated for right-hand cutting in steel alloy as its primary workpiece material, making it a go-to choice for HVAC, plumbing, and electrical trades drilling through steel framing, sheet metal, and structural members. The straight-cylindrical shank at 0.1800 inches in diameter fits standard 3-jaw chucks on both handheld and bench-mounted drills. The Series 150DH designation indicates a heavy-duty grade within the CHICAGO-LATROBE lineup, appropriate for repetitive production drilling where bit longevity is a factor.

Installation Notes

This bit is installed and used by machinists, pipefitters, electricians, and general trade professionals performing metal drilling operations. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before drilling. Use cutting fluid or lubricant when drilling steel alloy to extend bit life and maintain hole tolerance. Inspect the cutting edges before each use and replace the bit if the point shows signs of heat discoloration or edge breakdown.
