Chicago-Latrobe 49716 Taper Length Drill
The Chicago-Latrobe 49716 is a taper length drill bit designed for general purpose drilling applications. It features a 1/4 inch size and a 118 degree point angle with a radial point geometry. The bit is constructed from high speed steel with a black oxide finish.
Suited for general purpose drilling tasks
This bit suits users drilling deeper holes in metal, wood, or plastic where a standard jobber length is insufficient. The high speed steel construction handles common ferrous and non-ferrous materials. It is not intended for hardened steel, stainless steel, or high-volume production drilling requiring cobalt or carbide substrates.
1/4 inch diameter with taper length flute
The taper length design provides greater flute length and overall reach compared to jobber drills, allowing deeper hole drilling in a single pass. The 118 degree point centers well in general materials. The black oxide finish aids chip flow and corrosion resistance. High speed steel limits tool life in abrasive or high-heat applications where premium materials are needed.
Highlights
- 118-degree point angle centres the bit quickly
- Taper length reaches deeper holes without extension
- High-speed steel resists heat during prolonged drilling
- Black oxide finish reduces friction and chip welding

Questions about this item
What size drill chuck do I need for the 1/4 in shank on this 49716 bit?
A standard 1/4 in or larger three-jaw chuck will grip the straight shank securely; keyless or keyed models both work.
Will the 118 degree point cut cleanly in the mild steel I usually drill with older high-speed steel bits?
Yes, the 118 degree radial point is designed for general-purpose steel and produces similar chip formation to conventional HSS bits.
How can I confirm the black oxide coating is intact after the first few holes?
The surface should remain a uniform dark grey with no bright steel showing on the flutes or margins after drilling.
