Chicago-latrobe 44876 Taper Length Drill Bit Wire 26 Cobalt

Product Description

The CHICAGO-LATROBE 44876 is a taper length drill bit from the Series 520 line, manufactured from M42 cobalt high-speed steel (HSS-CO 8%) with an oxide gold coating. It is sized to wire gauge 26 (0.1470 inches decimal) and features a 135-degree split point for fast, accurate starts with minimal walking on hard or abrasive materials. The spiral flute, right-hand cut geometry produces a 3-inch flute length within a 5-3/8-inch overall length. This bit is sold individually and is typically installed and used by machinists, maintenance technicians, and trade professionals working with ferrous and high-strength alloys.

This bit is engineered for demanding material applications including cast iron, high-tensile steel, manganese steel, and titanium. The taper length body provides added reach compared to a jobber-length bit, making it well suited for drilling deeper holes without repositioning or using an extension. The web-thinned, tapered web configuration reduces thrust requirements in tough materials. Straight cylindrical shank accepts standard drill chucks without requiring special collets or adapters, making it compatible with common bench drill presses, hand drills, and CNC machine spindles.

Key Features

• M42 cobalt HSS-CO 8% construction for heat and wear resistance in high-tensile and abrasive alloys
• 135-degree split point reduces walking and lowers entry thrust on hard workpieces
• Oxide gold coating improves lubricity and surface hardness
• Web-thinned tapered web reduces cutting resistance and chip loading
• Taper length body at 5-3/8 inches OAL provides extended reach beyond standard jobber bits
• Right-hand spiral flute for efficient chip evacuation in through-hole and blind-hole drilling

Compatibility

Designed for use in cast iron, high-tensile steel, manganese steel, and titanium workpieces. Straight cylindrical shank fits standard drill chucks in bench drill presses, hand-held drills, and compatible CNC spindles accepting a 0.1470-inch diameter bit.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or trade technician familiar with proper drilling practices. Secure the workpiece firmly before drilling and confirm the chuck is fully tightened on the straight shank before starting the spindle. Use appropriate cutting fluid or coolant for the material being drilled to extend bit life, as coolant-through capability is not available on this bit. Inspect the cutting edges for wear before each use and replace when the point shows signs of chipping or dulling to avoid workpiece damage.
