Chicago-latrobe 69049 Jobber Drill Bit Size 49 Hss 135 Degree

Product Description

The CHICAGO-LATROBE 69049 is a heavy-duty jobber length drill bit designed for precision drilling in steel alloy and similar metalworking applications. Built from high speed steel with a bright uncoated finish, this bit features a 135-degree split point that reduces walking on contact and allows drilling without a center punch in most setups. The parabolic flute geometry promotes faster chip evacuation and cooler cutting, extending tool life during production runs. At 2 inches overall length with a 0.0730-inch diameter, it fits the wire gauge size 49 standard. The straight-cylindrical shank seats cleanly in standard drill chucks without slippage.

This bit is suited for metalworking operations in fabrication shops, maintenance and repair environments, and production drilling setups. The Series 150DH designation indicates a heavy-duty grade intended for drilling steel alloy workpieces where tool life and hole accuracy matter. The web-thinned, tapered web construction reduces thrust requirements and makes this bit a practical choice for hand drills, drill presses, and CNC drilling applications where small-diameter precision bits are required.

Key Features

• Wire gauge size 49 — 0.0730-inch diameter for tight-tolerance hole work
• 135-degree split point reduces drill walk and lowers thrust required to start a hole
• Parabolic flute design improves chip evacuation and reduces heat buildup
• Web-thinned, tapered web lowers cutting resistance in steel alloy materials
• High speed steel construction delivers durability in metalworking applications
• Bright uncoated finish — no coating buildup to affect hole diameter tolerance

Compatibility

Designed as an OEM-style jobber length drill bit for use in standard drill chucks accepting straight-cylindrical shanks in the 0.0500 to 0.1000-inch diameter range.

Installation Notes

Installation of small-diameter drill bits should be performed by qualified machinists or maintenance technicians familiar with metalworking equipment. Secure the shank fully in the drill chuck and verify concentricity before drilling. Power down and lock out all equipment before changing bits. Avoid excessive feed pressure on small-diameter bits — let the split point geometry and cutting speed do the work to prevent breakage.
