Osg 15177005 Cobalt Jobber Drill Bit Wire Size 16

Product Description

The OSG 15177005 is a cobalt jobber length drill bit designed for high-performance drilling in steel and alloy steel. It carries a Titanium Nitride (TiN) coating that extends cutting edge life and reduces friction during operation. The bit measures 3-5/8 inches overall length with a 2-3/16 inch flute length and a 3/16 inch straight-cylindrical shank. The 130-degree drill point angle and R-thinned web reduce entry force and improve self-centering. Two spiral flutes in a regular helix evacuate chips efficiently. This is a professional-grade cutting tool installed by machinists, maintenance mechanics, and metalworking trade technicians.

This drill bit is suited for use in steel and alloy steel workpieces across a range of production and maintenance applications. Its wire size 16 designation corresponds to 0.1770 decimal inch (4.50 mm) diameter, placing it in the 0.1500 to 0.2000 inch diameter range of the OSG Series 1500 line. Typical applications include blind hole drilling, cross hole drilling, through drilling, and self-centering operations on ferrous metals in both shop and field environments.

Key Features

• Titanium Nitride (TiN) coating reduces friction and extends tool life
• 130-degree split point with R-thinned web reduces walking and entry thrust
• Right-hand cut with regular spiral flutes for efficient chip evacuation
• Straight-cylindrical shank fits standard keyed and keyless drill chucks
• Diameter tolerance of +0 to -0.018 mm for consistent hole sizing

Compatibility

Designed for use in steel and alloy steel workpieces. Fits standard drill chucks accepting a 3/16 inch straight-cylindrical shank. Part of the OSG Series 1500 jobber length cobalt drill bit line covering the 0.1500 to 0.2000 inch diameter range.

Installation Notes

This drill bit is intended for use by qualified machinists and metalworking technicians. Secure the shank fully in the drill chuck before operation and verify chuck tightness. Coolant-through is not supported on this bit; use external cutting fluid on the workpiece as appropriate for the material. Inspect the cutting edge for wear before each use and replace the bit if chipping or excessive wear is observed.
