Chicago-latrobe 68976 Letter G Hss Jobber Drill Bit

Product Description

The CHICAGO-LATROBE 68976 is a jobber-length drill bit in the Series 150DH, designed for heavy-duty drilling in steel alloy and similar materials. Sized at Letter G (0.2610 inches), it features a 135-degree split point that reduces walking and minimizes the need for a center punch. The parabolic flute geometry clears chips aggressively, making it well suited for deep-hole applications and interrupted cuts. The bright, uncoated high speed steel construction maintains edge integrity across a wide range of shop and field conditions. Licensed HVAC, plumbing, and electrical contractors as well as general tradespeople rely on this bit for metal fabrication, conduit work, and bracket drilling.

This bit fits standard jobber-length applications where a 0.2610-inch diameter hole is required in steel alloy workpieces. The straight-cylindrical shank seats in 3-jaw chucks and quick-change drill drivers without adapters. The overall length of 4.125 inches and a flute length of 2.875 inches give it reach for most standard panel, strut, and sheet-metal drilling tasks encountered in mechanical and electrical trades. It is sold individually.

Key Features

• Letter G diameter: 0.2610 inches, with a tolerance of -0.0010 to 0.0000 inches for consistent hole sizing
• 135-degree split point reduces thrust and eliminates center-punch requirements on most steel alloy stock
• Parabolic flute design accelerates chip evacuation in deep or stacked-material drilling
• Web-thinned, tapered web lowers cutting resistance and extends tool life in heavy-duty use
• Bright uncoated high speed steel finish allows easy visual inspection of edge condition
• Right-hand cut, straight-cylindrical shank fits standard drill chucks without modification

Compatibility

Designed as a jobber-length replacement or production drill bit for use in standard 3-jaw chucks and compatible drill drivers where a Letter G (0.2610-inch) straight-shank bit is specified for steel alloy workpieces.

Installation Notes

Installation should be performed by qualified tradespeople familiar with rotary cutting tools and applicable shop-safety practices. Secure the shank fully in the chuck and verify concentricity before drilling. Disengage power and allow the spindle to come to a complete stop before changing bits or clearing chips. Do not exceed the recommended RPM range for the workpiece material and bit diameter as specified by the drill manufacturer.
