Osg 8612258 Jobber Length Drill Bit Wire Size 38

Product Description

The OSG 8612258 is a jobber length drill bit designed for high-performance metal drilling in professional machining and fabrication applications. Built from powdered metal with a V coating, this bit delivers extended tool life and wear resistance compared to standard high-speed steel. It carries a 130-degree split-point (X-thinned) tip that reduces walking on entry and minimizes the need for a center punch on most setups. The straight-cylindrical shank measures 3.00 millimeters in diameter, and the overall length is 62.00 millimeters with a flute length of 30.00 millimeters. The two-flute spiral design promotes chip evacuation in both through and blind hole applications.

This bit is suited for drilling steel, alloy steel, cast iron, and nickel alloys in production and maintenance environments. The X-thinned web and regular spiral geometry make it effective for blind hole drilling, cross hole operations, self-centering starts, and general drilling tasks. It is used by machinists, tool-and-die technicians, and maintenance professionals working with ferrous and nickel-based workpiece materials. The wire gauge size 38 corresponds to a decimal inch diameter of 0.1015 inches (2.58 millimeters), placing it in the 0.1000 to 0.1500 inch range category. Coolant-through capability is not available on this model.

Key Features

• Powdered metal construction with V coating for extended wear resistance in ferrous materials
• 130-degree drill point angle with X-thinned web reduces thrust and improves self-centering
• Two-flute regular spiral design promotes consistent chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Tapered web configuration adds rigidity along the flute length
• Diameter tolerance held to plus 0 to minus 0.014 millimeters for close-tolerance hole work

Compatibility

Designed for use on steel, alloy steel, cast iron, and nickel alloy workpieces. Compatible with standard drill chucks and collet systems accepting a 3.00 millimeter straight-cylindrical shank. Suitable for CNC machining centers, drill presses, and hand-held power tools where the shank diameter is supported.

Installation Notes

Secure the shank fully in the chuck or collet before operation to prevent runout. Machinists should verify spindle speed and feed rate are appropriate for the workpiece material and hole depth before starting. Inspect the cutting edge for wear or chipping before each use, particularly in production drilling of hardened alloys. Dispose of worn bits according to applicable shop safety procedures.
