Chicago-latrobe 50358 Taper Length Drill Bit 0.0310 in Hss

Product Description

The CHICAGO-LATROBE 50358 is a taper length twist drill bit designed for precise small-diameter drilling in metalworking applications. Built from high speed steel (HSS) with a coated finish for improved wear resistance, this bit measures 0.0310 inches in diameter with a 2-inch overall length and a 3/4-inch flute length. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and improve centering accuracy. The straight shank at 0.0310 inches in diameter seats securely in standard drill chucks, making this bit a reliable choice for production shops and tool-room setups that require consistent results in small-bore work.

This bit is suited for drilling alloy steel, carbon steel, and cast iron in both light manufacturing and maintenance environments. Series 120 taper length geometry provides a longer flute and overall length than jobber bits, giving better reach in deeper setups or fixture work. Right-hand spiral flute cutting clears chips efficiently during through-hole and blind-hole operations. Machinists, tool-and-die professionals, and maintenance mechanics working with drill presses, CNC machines, or hand-held equipment will find this bit appropriate for general-purpose small-diameter work.

Key Features

• High speed steel construction for durability in ferrous metal drilling
• Coated finish extends cutting life and reduces friction
• 118-degree standard point angle for general-purpose entry performance
• Web-thinned tapered web reduces thrust and improves chip evacuation
• Right-hand spiral flute promotes efficient chip clearing
• Straight shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill presses, CNC drilling setups, and hand-held drilling equipment accepting a 1/32-inch straight shank. Suitable for use in alloy steel, carbon steel, and cast iron workpieces.

Installation Notes

Install this bit in a properly sized drill chuck, ensuring the shank is fully seated and the chuck is tightened securely before operation. Apply appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain hole tolerance. Use recommended spindle speeds for the 0.0310-inch diameter to avoid overheating and premature wear. Inspect the cutting edges before each use and replace the bit if chipping or dullness is observed.
