Osg 15113005 Cobalt Jobber Drill Bit Wire 33 Tin

Product Description

The OSG 15113005 is a cobalt jobber-length drill bit in wire gauge size 33, with a decimal diameter of 0.1130 inches (2.87 mm). It carries a Titanium Nitride (TiN) coating applied over a cobalt steel body, which adds surface hardness and extends tool life in demanding drilling applications. The 130-degree split point reduces walking on entry and lowers thrust requirements at the spindle. With an overall length of 2-15/16 inches and a 1-1/2 inch flute length, this bit fits standard drill chucks and is suited for use in drill presses, CNC machines, and hand-held power drills. The straight cylindrical shank measures 3/16 inch in diameter. Machinists, tool-and-die workers, and maintenance technicians are the primary users.

This bit is designed for drilling in steel and alloy steel, including blind holes, cross holes, and self-centering applications. The regular spiral flute and right-hand cutting direction are consistent with standard metalworking drilling operations. The X-thinned web reduces cutting resistance in tougher ferrous materials. Sold individually, this bit is well suited for job-site or shop use where a single replacement bit in wire gauge size 33 is needed without purchasing a full index set.

Key Features

• Cobalt steel construction with TiN coating for extended tool life in steel and alloy steel
• 130-degree drill point angle reduces walking and lowers entry thrust
• X-thinned, tapered web for reduced cutting resistance
• Right-hand cut, regular spiral flute for standard metalworking applications
• Straight cylindrical shank compatible with standard drill chucks
• Rated for blind hole, cross hole, drilling, and self-centering tool applications

Compatibility

Designed as an OEM-style replacement or direct substitute for wire gauge size 33 jobber-length drill bits used in metalworking, maintenance, and general-purpose drilling setups.

Installation Notes

Installation of this bit is performed by machinists or maintenance technicians familiar with drill press or CNC machine operation. Power down and lock out the spindle before changing bits. Secure the straight cylindrical shank fully in the chuck before applying cutting force. Always use appropriate cutting fluid or cooling method when drilling steel or alloy steel to prevent premature coating wear.
