Chicago-Latrobe 49742 Taper Length Drill Bit

The Chicago-Latrobe 49742 is a 21/32 in taper length drill bit designed for general purpose drilling tasks. It suits machinists and technicians who need extended reach for deeper holes in metal, wood, or plastic materials.

High Speed Steel Construction

The bit is made from high speed steel with a black oxide coating that resists corrosion and reduces friction during operation. Its 118 degree radial point geometry allows for accurate centering without a pilot hole on most common workpiece surfaces.

Replaces Shorter Jobber Length Bits for Deep Hole

This taper length bit upgrades from standard jobber drills when hole depth exceeds the shorter flute length capacity. The switch is worth it when drilling through thick plate, pipe walls, or stacked materials where extra flute length prevents frequent bit withdrawal.

Questions about this item

What drill chuck capacity does the 21/32-inch bit require?

The bit has a 21/32-inch straight shank, so the drill chuck must open wide enough to grip that diameter securely.

How much flute length does the taper-length design add over a jobber bit?

The taper-length body provides extra flute length for deeper holes without changing the 21/32-inch cutting diameter.

What is the correct speed and feed for the 118-degree high-speed-steel point?

Run the bit at standard high-speed-steel speeds for the workpiece material and apply steady pressure to keep the 118-degree radial point cutting cleanly.
