Chicago-latrobe 68824 Taper Length Drill Bit 3/8 in Hss

Product Description

The CHICAGO-LATROBE 68824 is a taper length drill bit engineered for heavy-duty drilling in metalworking applications. It carries a 3/8 inch (0.3750 inch) diameter and a 135-degree split point that self-centers on contact, reducing the need for a center punch on most metal surfaces. The parabolic flute geometry promotes fast chip evacuation and keeps the bit running cool during deep drilling passes. Constructed from high speed steel with a bright, uncoated finish, the 68824 is a go-to bit for machinists, tool-and-die technicians, and maintenance trades who need reliable performance on ferrous and non-ferrous stock.

This bit is suited for production and job-shop drilling in alloy steel, carbon steel, aluminum, and other non-ferrous metals. The taper length body provides extra reach compared to a jobber-length bit, making it practical for drilling deeper holes without repositioning or using extensions. The tanged shank seats securely in taper-shank drill press spindles and compatible chuck adapters. It fits typical drill press and CNC drilling setups where a taper shank interface is specified.

Key Features

• 135-degree split point for self-centering starts without a center punch
• Parabolic flute design accelerates chip removal in deep-hole drilling
• High speed steel construction rated for heavy-duty service in steel and non-ferrous metals
• Tanged taper shank provides positive drive and easy drift-key removal
• Web-thinned, tapered web configuration reduces thrust and heat buildup
• Bright/uncoated finish allows easy visual inspection for wear or damage

Compatibility

Designed for use in taper-shank drill press spindles and compatible adapters that accept a 0.3750 inch tanged shank. Suitable for drilling alloy steel, carbon steel, aluminum, and non-ferrous metals as stated in manufacturer specifications for Series 120DH.

Installation Notes

Installation is performed by machinists or qualified maintenance technicians using a drill press or CNC drilling machine equipped with a matching taper-shank spindle. Secure the tanged shank fully into the spindle socket before applying power, and use the appropriate drift key for removal — never strike the bit directly. Ensure the workpiece is clamped or fixtured to prevent rotation before beginning a drilling pass. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speeds and feed rates based on material type.
