Chicago-latrobe 50329 Taper Length Drill Bit 0.0995 in

Product Description

The CHICAGO-LATROBE 50329 is a taper length twist drill bit designed for general-purpose drilling in metal and ferrous materials. Built from high speed steel (HSS) with a coated finish, it features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip clearance at the cutting tip. The bit measures 0.0995 inches in diameter with a spiral flute length of 2.5 inches and an overall length of 4.625 inches. The straight shank and right-hand cut make it compatible with standard drill chucks. Licensed HVAC techs, machinists, plumbers, and general tradespeople reach for this size when drilling pilot holes, clearance holes, or precision-sized openings in tight tolerances.

The 50329 is suited for drilling alloy steel, carbon steel, and cast iron in both shop and field applications. The taper length design provides extra reach compared to jobber-length bits, making it useful where standard-length bits cannot access a worksite geometry. The 0.0995-inch diameter corresponds to wire gauge size 39, a common reference size in precision metalworking, HVAC bracket fabrication, and plumbing rough-in work. General-purpose grade performance covers production drilling and maintenance drilling at moderate speeds without specialized coolant systems, since coolant-through is not supported on this bit.

Key Features

• High speed steel construction for durability in ferrous and alloy steel applications
• Coated finish to reduce friction and extend cutting life
• 118-degree standard point angle for general-purpose entry on flat and curved stock
• Web-thinned tapered web reduces cutting resistance and improves chip evacuation
• Taper length body (4.625 inches overall) provides extra reach over jobber-length bits
• Right-hand spiral flute with straight shank fits standard three-jaw drill chucks

Compatibility

Designed as a general-purpose taper length drill bit rated for alloy steel, carbon steel, and cast iron. Compatible with any standard drill chuck accepting a 0.0995-inch straight shank.

Installation Notes

A licensed machinist or qualified tradesperson should secure workpieces firmly before drilling to prevent rotation and bit breakage. Power down or de-energize any equipment before drilling into it for maintenance or modification. Use appropriate cutting fluid or lubricant when drilling into hard alloy steel to extend bit life, even though this bit does not support coolant-through delivery. Dispose of metal chips safely and wear eye protection per applicable shop safety standards.
