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.

Questions about this item
How can I confirm the 29/64 in drill bit is drilling correctly after I start using it?
The 118 degree radial point should centre itself and produce clean, round holes in steel without wandering when the bit is sharp and running at the proper speed.
What comes in the box with the Chicago-Latrobe 49729 taper length drill bit and what must I purchase separately?
The box contains the single 29/64 in high-speed steel bit with black oxide finish; a drill chuck, cutting fluid and workpiece clamping are not included.
Which version of the Chicago-Latrobe 49729 should I choose for general-purpose drilling in steel?
The listed 29/64 in size with 118 degree radial point and black oxide coating is the only version offered and is intended for general-purpose steel drilling.
