Osg 200-1130 Solid Carbide Jobber Drill Bit No. 33

Product Description

The OSG 200-1130 is a solid carbide jobber-length drill bit sized to wire gauge No. 33, with a decimal diameter of 0.1130 inches (2.87 mm). It features a 140-degree web-thinned point and a straight flute geometry, making it well suited for drilling precise, small-diameter holes in ferrous materials. The bright, uncoated carbide construction provides consistent performance in general-purpose drilling applications. With an overall length of 1.874 inches (47.60 mm) and a flute length of 0.874 inches (22.20 mm), this bit fits standard drill chucks and CNC spindles. It is typically installed by machinists, tool-and-die technicians, and maintenance professionals.

This drill bit is designed for use in steel and cast iron workpieces, covering primary material codes P and K. It handles blind hole drilling, cross hole drilling, through-hole drilling, and self-centering applications. The straight-cylindrical shank and two-flute configuration make it compatible with standard collets and keyless chucks used in manual drill presses, CNC machining centers, and hand-held power drills. General-purpose performance classification means it is appropriate for production runs and repair work where consistent hole quality in ferrous materials is required.

Key Features

• Solid carbide construction for wear resistance in steel and cast iron
• 140-degree web-thinned point reduces thrust and improves self-centering
• Straight flute design suitable for short-chip materials
• Bright uncoated finish for use with or without coolant (coolant-through not applicable)
• Diameter tolerance of +0 to -0.013 mm for consistent hole sizing
• Two-flute straight geometry supports blind hole and cross hole operations

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide jobber drill bit for general-purpose machining in steel and cast iron; compatible with standard straight-cylindrical shank collets and chucks accepting a 2.87 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with small-diameter carbide tooling. Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the spindle speed required by the workpiece material before operation. Carbide tooling is brittle — avoid side loads, interrupted cuts without proper setup, and dropping or impacting the cutting edges. Verify spindle runout is within tolerance before use to prevent premature breakage of this small-diameter bit.
