Chicago-Latrobe 49729 29/64 in 118 Degree Taper Length Drill Bit

Chicago-Latrobe 49729 29/64 in Drill Bit

The Chicago-Latrobe 49729 is a taper length drill bit designed for general purpose drilling tasks. It features a 29/64 inch diameter and a 118 degree radial point angle. The bit is constructed from high speed steel with a black oxide finish for durability. It suits professionals and DIY users needing a standard tapered shank bit.

Standard Shank Installation and Common Issues

Installation requires a compatible taper length chuck or collet that matches the bit's shank configuration. Ensure the shank seats fully and securely to prevent runout during operation. A common issue arises from using incorrect chuck types, leading to slippage or misalignment. Dulling can occur rapidly if used on hardened materials without proper cooling.

Capacity Headroom for General Drilling

The 29/64 inch size handles medium diameter hole requirements in wood, plastic, and mild steel effectively. High speed steel construction provides adequate wear resistance for repetitive drilling in softer alloys. The bit reaches its limit in abrasive or high tensile strength materials where cobalt or carbide tooling becomes necessary. The 118 degree point is optimised for standard drilling rather than specialised angled entry.
