Chicago-latrobe 68818 Taper Length Drill Bit 9/32 in

Product Description

The CHICAGO-LATROBE 68818 is a taper length, high speed steel drill bit designed for demanding metal drilling applications in industrial and trade environments. It measures 9/32 inch (0.2812 inches) in diameter with a 135-degree split point that self-centers on contact, reducing the need for a center punch and minimizing walking on hard surfaces. The parabolic flute geometry promotes efficient chip evacuation, especially useful when drilling deeper holes in alloy and carbon steels. A bright, uncoated finish keeps friction low during entry. Machinists, maintenance mechanics, and fabrication professionals specify this bit for production and repair work where standard-length bits fall short.

The 68818 suits applications in metal fabrication shops, maintenance and repair operations, and light industrial production environments. Its taper length profile gives more reach than a jobber bit without sacrificing rigidity. The split point and web-thinned construction make it practical for drilling alloy steel, carbon steel, aluminum, and other non-ferrous metals without a pilot hole. The tanged shank provides a positive drive connection in compatible Morse taper holders, making it a common choice for drill press and tapping machine setups where slippage under load is a concern.

Key Features

• 135-degree split point with web thinning for self-centering entry without a center punch
• Parabolic flute design accelerates chip evacuation in deeper cuts
• High speed steel (HSS) construction for durability across a range of metal workpieces
• Tanged shank for positive drive in Morse taper drill holders
• Tapered web configuration maintains core strength along the full flute length
• Right-hand cut, 5-inch flute length with 6.25-inch overall length for extended reach

Compatibility

Rated for use in alloy steel, aluminum, carbon steel, and non-ferrous metals. Designed as a taper length replacement or upgrade for applications where jobber-length HSS drill bits lack sufficient reach. Tanged shank fits standard Morse taper drill chucks and holders sized for a 0.2812-inch shank diameter.

Installation Notes

Install and remove this bit only with the machine fully powered down and the spindle at a complete stop. Secure the tanged shank firmly in the Morse taper socket before applying any feed pressure to prevent shank pullout under load. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole-diameter tolerance. Inspect the cutting edges and flutes for chips or wear before each use; a damaged split point will produce oversized or off-center holes.
